    Power Point that explains the physics of a rainbow. What is a rainbow? What will affect if you see a rainbow or two? What do dispersion, refraction, and reflection have to do with rainbows?
    Technical violations of parole, such as failing to inform a parole officer about a change in residence, contribute significantly to prison overcrowding. Evaluate the effectiveness of returning parolees to prison for technical violations. Should there be more leniency in handling these cases, or is strict enforcement necessary to maintain public safety and the integrity of the parole system? Discuss the benefits and problems associated with strict enforcement of technical violations, considering the potential impact on recidivism rates, prison overcrowding, and the successful reintegration of parolees into society. Be sure to include examples from the textbook in your answer.

    Objectives:

    The objective of this activity is to investigate the relationship between the equivalent resistance

    and individual resistors connected in series and parallel. We will also investigate the voltage

    across and current through resistors connected in series and parallel using simulation software.

    Theory:

    Before starting the experiment, there are a few concepts and equations that need to be known in

    order to perform the lab:

    •A combination of resistors in a circuit can be replaced with an equivalent (total) resistor that

    does not alter the circuit and has the same total current and potential difference as the actual

    resistors.

    •The relationship between the current, voltage, and resistance is given by Ohm’s law:

    𝑽 = 𝑰𝑹

    • Where:

    o V = voltage or potential difference (V)

    o I = current (A)

    o R = resistance (Ω)

    •Resistors connected in series have the same current flowing through them. The equivalent

    (total) resistance, current, and voltage of series combination are given by:

    • 𝑹𝑻 = 𝑹𝟏 + 𝑹𝟐 + 𝑹𝟑 +⋯

    • 𝑰𝑻 = 𝑰𝟏 = 𝑰𝟐 = 𝑰𝟑 = ⋯

    • 𝑽𝑻 = 𝑽𝟏 + 𝑽𝟐 + 𝑽𝟑 +⋯

    •Resistors connected in parallel have the same voltage applied across them. The equivalent

    (total) resistance, current, and voltage of parallel combination are given by:

    •
    𝟏

    𝑹𝑻
    =

    𝟏

    𝑹𝟏
    +

    𝟏

    𝑹𝟐
    +

    𝟏

    𝑹𝟑
    +⋯

    • 𝑰𝑻 = 𝑰𝟏 = 𝑰𝟐 = 𝑰𝟑 = ⋯

    • 𝑽𝑻 = 𝑽𝟏 + 𝑽𝟐 + 𝑽𝟑 +⋯

    •In this activity, we will simulate three resistors in various combinations in a circuit. We will

    measure the current through the resistors, and the voltage cross the resistors.

    •We will determine the experimental value of the equivalent resistance (RT Exp) using Ohm’s

    law and the accepted value of the equivalent resistance (RT Acc) using the given equations.

    = 9.38 Ω

    % Error = ( (9.35 Ω – 9.38 Ω) / 9.35 Ω ) x 100% = 0.32%

    Conclusions:

    In Trial 1 of Part A, the total experiment voltage was 120.1 V. This resulted in a 0.08% error.

    The total experimental current was calculated to be 0.81 A with a 0.00% error. The accepted

    value of the total resistance was 148 Ω, which I successfully calculated with a 0.00% error. For

    trial 2 we yielded the same results despite the same placement of each resistor. We yielded a

    voltage of 120.1 V, an experimental current of 0.81 A and the total resistance of 148 Ω.

    In Trial 1 of Part B, the total experiment voltage was 120.0 V. This resulted in a 0.00% error.

    The total experimental current was calculated to be 12.8 A with a 0.00% error. The total

    accepted resistance was calculated to be 9.35 Ω while the total experimental resistance was

    calculated to be 9.38 Ω, which I successfully calculated with a 0.32% error. For both trials we

    yielded the same results despite the same placement of each resistor. So I conclude that the

    position of the resistor doesn’t have any effect on the results as long as the values are the same in

    each trial.

    The final results obtained from the simulation do agree with the theory of this lab. The theory

    stated that through Ohm’s Law voltage, the current is directly proportional to the voltage, and

    inversely proportional to the resistance. When calculating our percent error for current and

    resistance, it remained low, ranging from 0% – 2.21%. The low percent proved that the experiment

    was accurate and precise. The placement and order of resistors has a great effect overall on all

    parts of the experiment. Because they control the control of energy, similar to a dam, the remaining

    electricity that can move throughout the system differs. This also depends on the strength of each

    resistor.

    Sources of Error:

    The sources of error in this experiment maybe from:

    • Inaccurate measurements of the voltmeter and ammeter.

    • The quality of wires could greatly affect the measured conductivity.

    • The uneven placement of the battery and resistors can also have an effect on the readings.

    • The battery’s output would affect the proper voltage to perform the lab.

    value of the total resistance was 148 Ω, which I successfully calculated with a 0.00% error. For

    trial 2 we yielded the same results despite the same placement of each resistor. We yielded a

    voltage of 120.1 V, an experimental current of 0.81 A and the total resistance of 148 Ω.

    In Trial 1 of Part B, the total experiment voltage was 120.0 V. This resulted in a 0.00% error.

    The total experimental current was calculated to be 12.8 A with a 0.00% error. The total

    accepted resistance was calculated to be 9.35 Ω while the total experimental resistance was

    calculated to be 9.38 Ω, which I successfully calculated with a 0.32% error. For both trials we

    yielded the same results despite the same placement of each resistor. So I conclude that the

    position of the resistor doesn’t have any effect on the results as long as the values are the same in

    each trial.

    The final results obtained from the simulation do agree with the theory of this lab. The theory

    stated that through Ohm’s Law voltage, the current is directly proportional to the voltage, and

    inversely proportional to the resistance. When calculating our percent error for current and

    resistance, it remained low, ranging from 0% – 2.21%. The low percent proved that the experiment

    was accurate and precise. The placement and order of resistors has a great effect overall on all

    parts of the experiment. Because they control the control of energy, similar to a dam, the remaining

    electricity that can move throughout the system differs. This also depends on the strength of each

    resistor.

    Sources of Error:

    The sources of error in this experiment maybe from:

    • Inaccurate measurements of the voltmeter and ammeter.

    • The quality of wires could greatly affect the measured conductivity.

    • The uneven placement of the battery and resistors can also have an effect on the readings.

    • The battery’s output would affect the proper voltage to perform the lab.

    Online Lab 7 – Resistors in Series and Parallel

    University Name

    PHYS 1110 – 01

    21 March 2021

    Dr. Nader Copty

    Objectives:

    The objective of this activity is to investigate the relationship between the equivalent resistance

    and individual resistors connected in series and parallel. We will also investigate the voltage

    across and current through resistors connected in series and parallel using simulation software.

    Theory:

    Before starting the experiment, there are a few concepts and equations that need to be known in

    order to perform the lab:

    •A combination of resistors in a circuit can be replaced with an equivalent (total) resistor that

    does not alter the circuit and has the same total current and potential difference as the actual

    resistors.

    •The relationship between the current, voltage, and resistance is given by Ohm’s law:

    𝑽 = 𝑰𝑹

    • Where:

    o V = voltage or potential difference (V)

    o I = current (A)

    o R = resistance (Ω)

    •Resistors connected in series have the same current flowing through them. The equivalent

    (total) resistance, current, and voltage of series combination are given by:

    • 𝑹𝑻 = 𝑹𝟏 + 𝑹𝟐 + 𝑹𝟑 +⋯

    • 𝑰𝑻 = 𝑰𝟏 = 𝑰𝟐 = 𝑰𝟑 = ⋯

    • 𝑽𝑻 = 𝑽𝟏 + 𝑽𝟐 + 𝑽𝟑 +⋯

    •Resistors connected in parallel have the same voltage applied across them. The equivalent

    (total) resistance, current, and voltage of parallel combination are given by:

    •
    𝟏

    𝑹𝑻
    =

    𝟏

    𝑹𝟏
    +

    𝟏

    𝑹𝟐
    +

    𝟏

    𝑹𝟑
    +⋯

    • 𝑰𝑻 = 𝑰𝟏 = 𝑰𝟐 = 𝑰𝟑 = ⋯

    • 𝑽𝑻 = 𝑽𝟏 + 𝑽𝟐 + 𝑽𝟑 +⋯

    •In this activity, we will simulate three resistors in various combinations in a circuit. We will

    measure the current through the resistors, and the voltage cross the resistors.

    •We will determine the experimental value of the equivalent resistance (RT Exp) using Ohm’s

    law and the accepted value of the equivalent resistance (RT Acc) using the given equations.

    Online Lab 7 – Resistors in Series and Parallel

    University Name

    PHYS 1110 – 01

    21 March 2021

    Dr. Nader Copty

    Objectives:

    The objective of this activity is to investigate the relationship between the equivalent resistance

    and individual resistors connected in series and parallel. We will also investigate the voltage

    across and current through resistors connected in series and parallel using simulation software.

    Theory:

    Before starting the experiment, there are a few concepts and equations that need to be known in

    order to perform the lab:

    •A combination of resistors in a circuit can be replaced with an equivalent (total) resistor that

    does not alter the circuit and has the same total current and potential difference as the actual

    resistors.

    •The relationship between the current, voltage, and resistance is given by Ohm’s law:

    𝑽 = 𝑰𝑹

    • Where:

    o V = voltage or potential difference (V)

    o I = current (A)

    o R = resistance (Ω)

    •Resistors connected in series have the same current flowing through them. The equivalent

    (total) resistance, current, and voltage of series combination are given by:

    • 𝑹𝑻 = 𝑹𝟏 + 𝑹𝟐 + 𝑹𝟑 +⋯

    • 𝑰𝑻 = 𝑰𝟏 = 𝑰𝟐 = 𝑰𝟑 = ⋯

    • 𝑽𝑻 = 𝑽𝟏 + 𝑽𝟐 + 𝑽𝟑 +⋯

    •Resistors connected in parallel have the same voltage applied across them. The equivalent

    (total) resistance, current, and voltage of parallel combination are given by:

    •
    𝟏

    𝑹𝑻
    =

    𝟏

    𝑹𝟏
    +

    𝟏

    𝑹𝟐
    +

    𝟏

    𝑹𝟑
    +⋯

    • 𝑰𝑻 = 𝑰𝟏 = 𝑰𝟐 = 𝑰𝟑 = ⋯

    • 𝑽𝑻 = 𝑽𝟏 + 𝑽𝟐 + 𝑽𝟑 +⋯

    •In this activity, we will simulate three resistors in various combinations in a circuit. We will

    measure the current through the resistors, and the voltage cross the resistors.

    •We will determine the experimental value of the equivalent resistance (RT Exp) using Ohm’s

    law and the accepted value of the equivalent resistance (RT Acc) using the given equations.

    Conclusions:

    In Trial 1 of Part A, the total experiment voltage was 120.1 V. This resulted in a 0.08% error.

    The total experimental current was calculated to be 0.81 A with a 0.00% error. The accepted

    value of the total resistance was 148 Ω, which I successfully calculated with a 0.00% error. For

    trial 2 we yielded the same results despite the same placement of each resistor. We yielded a

    voltage of 120.1 V, an experimental current of 0.81 A and the total resistance of 148 Ω.

    In Trial 1 of Part B, the total experiment voltage was 120.0 V. This resulted in a 0.00% error.

    The total experimental current was calculated to be 12.8 A with a 0.00% error. The total

    accepted resistance was calculated to be 9.35 Ω while the total experimental resistance was

    calculated to be 9.38 Ω, which I successfully calculated with a 0.32% error. For both trials we

    yielded the same results despite the same placement of each resistor. So I conclude that the

    position of the resistor doesn’t have any effect on the results as long as the values are the same in

    each trial.

    The final results obtained from the simulation do agree with the theory of this lab. The theory

    stated that through Ohm’s Law voltage, the current is directly proportional to the voltage, and

    inversely proportional to the resistance. When calculating our percent error for current and

    resistance, it remained low, ranging from 0% – 2.21%. The low percent proved that the experiment

    was accurate and precise. The placement and order of resistors has a great effect overall on all

    parts of the experiment. Because they control the control of energy, similar to a dam, the remaining

    electricity that can move throughout the system differs. This also depends on the strength of each

    resistor.

    Sources of Error:

    The sources of error in this experiment maybe from:

    • Inaccurate measurements of the voltmeter and ammeter.

    • The quality of wires could greatly affect the measured conductivity.

    • The uneven placement of the battery and resistors can also have an effect on the readings.

    • The battery’s output would affect the proper voltage to perform the lab.

    Conclusions:

    In Trial 1 of Part A, the total experiment voltage was 120.1 V. This resulted in a 0.08% error.

    The total experimental current was calculated to be 0.81 A with a 0.00% error. The accepted

    value of the total resistance was 148 Ω, which I successfully calculated with a 0.00% error. For

    trial 2 we yielded the same results despite the same placement of each resistor. We yielded a

    voltage of 120.1 V, an experimental current of 0.81 A and the total resistance of 148 Ω.

    In Trial 1 of Part B, the total experiment voltage was 120.0 V. This resulted in a 0.00% error.

    The total experimental current was calculated to be 12.8 A with a 0.00% error. The total

    accepted resistance was calculated to be 9.35 Ω while the total experimental resistance was

    calculated to be 9.38 Ω, which I successfully calculated with a 0.32% error. For both trials we

    yielded the same results despite the same placement of each resistor. So I conclude that the

    position of the resistor doesn’t have any effect on the results as long as the values are the same in

    each trial.

    The final results obtained from the simulation do agree with the theory of this lab. The theory

    stated that through Ohm’s Law voltage, the current is directly proportional to the voltage, and

    inversely proportional to the resistance. When calculating our percent error for current and

    resistance, it remained low, ranging from 0% – 2.21%. The low percent proved that the experiment

    was accurate and precise. The placement and order of resistors has a great effect overall on all

    parts of the experiment. Because they control the control of energy, similar to a dam, the remaining

    electricity that can move throughout the system differs. This also depends on the strength of each

    resistor.

    Sources of Error:

    The sources of error in this experiment maybe from:

    • Inaccurate measurements of the voltmeter and ammeter.

    • The quality of wires could greatly affect the measured conductivity.

    • The uneven placement of the battery and resistors can also have an effect on the readings.

    • The battery’s output would affect the proper voltage to perform the lab.

    Online Lab 7 – Resistors in Series and Parallel

    University Name

    PHYS 1110 – 01

    21 March 2021

    Dr. Nader Copty

    Objectives:

    The objective of this activity is to investigate the relationship between the equivalent resistance

    and individual resistors connected in series and parallel. We will also investigate the voltage

    across and current through resistors connected in series and parallel using simulation software.

    Theory:

    Before starting the experiment, there are a few concepts and equations that need to be known in

    order to perform the lab:

    •A combination of resistors in a circuit can be replaced with an equivalent (total) resistor that

    does not alter the circuit and has the same total current and potential difference as the actual

    resistors.

    •The relationship between the current, voltage, and resistance is given by Ohm’s law:

    𝑽 = 𝑰𝑹

    • Where:

    o V = voltage or potential difference (V)

    o I = current (A)

    o R = resistance (Ω)

    •Resistors connected in series have the same current flowing through them. The equivalent

    (total) resistance, current, and voltage of series combination are given by:

    • 𝑹𝑻 = 𝑹𝟏 + 𝑹𝟐 + 𝑹𝟑 +⋯

    • 𝑰𝑻 = 𝑰𝟏 = 𝑰𝟐 = 𝑰𝟑 = ⋯

    • 𝑽𝑻 = 𝑽𝟏 + 𝑽𝟐 + 𝑽𝟑 +⋯

    •Resistors connected in parallel have the same voltage applied across them. The equivalent

    (total) resistance, current, and voltage of parallel combination are given by:

    •
    𝟏

    𝑹𝑻
    =

    𝟏

    𝑹𝟏
    +

    𝟏

    𝑹𝟐
    +

    𝟏

    𝑹𝟑
    +⋯

    • 𝑰𝑻 = 𝑰𝟏 = 𝑰𝟐 = 𝑰𝟑 = ⋯

    • 𝑽𝑻 = 𝑽𝟏 + 𝑽𝟐 + 𝑽𝟑 +⋯

    •In this activity, we will simulate three resistors in various combinations in a circuit. We will

    measure the current through the resistors, and the voltage cross the resistors.

    •We will determine the experimental value of the equivalent resistance (RT Exp) using Ohm’s

    law and the accepted value of the equivalent resistance (RT Acc) using the given equations.

    position of the resistor doesn’t have any effect on the results as long as the values are the same in

    each trial.

    The final results obtained from the simulation do agree with the theory of this lab. The theory

    stated that through Ohm’s Law voltage, the current is directly proportional to the voltage, and

    inversely proportional to the resistance. When calculating our percent error for current and

    resistance, it remained low, ranging from 0% – 2.21%. The low percent proved that the experiment

    was accurate and precise. The placement and order of resistors has a great effect overall on all

    parts of the experiment. Because they control the control of energy, similar to a dam, the remaining

    electricity that can move throughout the system differs. This also depends on the strength of each

    resistor.

    Sources of Error:

    The sources of error in this experiment maybe from:

    • Inaccurate measurements of the voltmeter and ammeter.

    • The quality of wires could greatly affect the measured conductivity.

    • The uneven placement of the battery and resistors can also have an effect on the readings.

    • The battery’s output would affect the proper voltage to perform the lab.

    discussion-  **Discussion Topic**

    Scientists such as Heinrich Hertz, Philipp Lenard, Max Planck, and Albert Einstein made scientific contributions that ultimately demonstrated that light is electromagnetic radiation, and that it has a “dual nature.” Some electromagnetic phenomena are best explained with a particle model, and some with a wave model. In a sense, “wave” and “particle” are just easy mental models for light. We employ them because we are used to seeing waves and particles—such as those in water waves and baseballs—in our daily lives. Electromagnetic radiation is a basic concept in physics, but it doesn’t fit completely into one of these neat little boxes.

    Research and discuss at least one modern technology that employs electromagnetic radiation and that can be explained by the wave model, the particle model, or a combination of the two. Some possible technologies include solar panels, burglar alarms, cameras, and cell phones.

    In this activity, you’ll use a video measurement and analysis tool called Tracker. Tracker enables you to create two different types of mathematical models: analytical and dynamic. In an analytical model, you can enter mathematical expressions for _x_ and _y_ positions as a function of time. That’s sometimes useful, but from a physics perspective, a dynamic model is much more flexible and powerful.

    With a dynamic model, you can set the initial conditions for a particular system (initial positions and velocities); then you can mathematically define any forces acting on that system. Once those are set up, the model becomes like an object in space, responding to the forces you’ve imposed on it. It might continue moving forever, if that’s what the forces would do to an object in real life. By visually matching a marker for your model to the real motion on the video, you can define and refine a mathematical model for a wide range of real-world situations.

    In this activity, you’ll use Tracker to observe the displacement, velocity, and acceleration of a mass on a spring. Tracker is a free scientific tool available through the Open Source Physics Project.

    **Preparation – Creating a Dynamic Particle Model**

    If you’ve never built a dynamic model before using Tracker, you’ll need to prepare a bit and find out where you can get help in creating your models. In Tracker, you can always access illustrated Help. For this project, you’re going to need to check out the Tracker Help instructions for creating a dynamic model.

    In Tracker, just click on the **Help** **menu**, then, click **Tracker** **Help**. In the Tracker Help window, click **Particle** **Models**. This short, illustrated document tells you everything you need to know to create a dynamic particle model in Tracker. You can print this Help document, but it is available from Tracker anytime you need to refer to it.

    **Instructions – Building your Dynamic Model**

    Start your activity by opening this Tracker experiment: [Spring Wars model](https://app.edmentum.com/redirect//343215)

    You’ve seen the motion of a mass on a spring where the motion is largely “undamped”; that is, it continues for a very long time at about the same amplitude. There are two common ways to slow down an object in harmonic motion:

    – kinetic friction – directly proportional to weight and opposite the direction of velocity
    – spring damping – directly proportional to velocity and opposite the direction of velocity

    Both of these damping forces are at work in this video, but the frictional force is by far the most significant here.

    A dynamic model is already started for you in this file. Follow the two steps in the screen captures below to open the model setup and begin your modeling work.

    1. Select the point mass **Model**.

    (from the blue pull-down control in the top menu)

    ![Selecting model from pull-down option in the top menu.](https://cdn.app.edmentum.com/EdAssets/f6cebd462aaf4162bafec1db7164a036?ts=636101174434130000)

    1. Open the **Model Builder**.

    (from the “Model” mass pull-down menu)

    ![Selecting model builder from the upper pull-down menu.](https://cdn.app.edmentum.com/EdAssets/af451b92e2ea461fa157237d74e0ce50?ts=636101174724430000)

    1. Once you’ve opened the Model Builder screen, use the **Tracker Help** documentation to begin filling out the basic information about this motion. You only have complete data table information starting at time _t_ = 0.00 seconds, so use that as your initial time. Enter data in each of the three sections:

    – parameters –Set m = 0.250 kilograms. Add a parameter _k_ for the spring constant and a parameter _mk_ for the coefficient of kinetic friction.
    – initial values – From the data table, enter those that apply to this _x_-direction motion: _t_, _x_, and _vx_.
    – force functions – It will be easier and cleaner to enter the force function as a sum of two forces, the spring force and the frictional force: _**fx**_: _Fs_ + _Ff_. (Notice that this section turns red after you enter the force functions, since you have not defined _Fs_ and _Ff_ yet.)
    – Add a new force function for _Fs_, the spring force. Note that the equilibrium point is at _x_ = 0, so this force law should be pretty easy for you.
    – Add a new force function for _Ff_, the frictional force.

    Frictional force is defined as _Ff_ = _µkmg_, where _µk_ is the coefficient of kinetic friction. Since this force has to be opposite the direction of motion, though, and since the direction of motion keeps changing, you must use a little creativity to define it. You basically just need something that will output +1 or -1, depending on the direction of your velocity.

    v⁢x|v⁢x|can be your “magic factor” here: +1 if velocity is (+) and -1 if velocity is (-).

    So, you just need to figure out how to write the following expression into the Tracker model:

    Ff=−μk⁢m⁢g⁡(v⁢x|v⁢x|)

    1. Finally, to make your model work, you’ll have to find values for the spring constant _k_ and the coefficient of friction _μk_. You’ll just have to play around with _μk_, but you can get close to the spring constant value by looking at some of your data. The first question below will help you with that.

    ## **Part A**

    Calculate the spring constant.

    – Look at the graph of _x_ vs. _t_ graph. (You may want to double-click on it to examine it in the **Data Tool** view.)
    – From the graph, determine the period _T_.
    – The first video frame lists the mass.
    – Use the equation below to solve for the spring constant _k_. Show your work below.

    T=2⁢π square root ⁢mk

    15pxSpace used(includes formatting): 0 / 30000

    ## **Part B**

    Enter into the table your calculated value for the spring constant, then play with different values of mk until you get a close match to the motion. (Note: It will never be perfect. Remember that there are two kinds of spring damping. Both are at work here, but we are not going to model both.) Once you’re satisfied with your model, record your model values in the table below.

        Variables               Expression

    parameter: _m_

    parameter: _k_

    parameter _: mk_

    initial value: _t_

    initial value: _x_

    initial value: _vx_

    _fx_

    _Fs_

    _Ff_

    10ptSpace used(includes formatting): 1376 / 30000

    ## **Part C**

    Describe how your model works compared to the actual spring motion. When are they close together? When are they not so close?

    15pxSpace used(includes formatting): 0 / 30000

    ## **Part D**

    Now that you’ve had some experience with damped harmonic motion, describe two different real-world harmonic motions you’ve seen—one with very little damping and the other with noticeable damping. Describe how those two motions differ and are the same.

    ## **Amusement Park Physics**

    Amusement parks provide many hours of fun, but did you know you can also practice your physics there? Yes, parks rides rely on physics to function. Let’s look at rides that travel in a circular path, such as a roller coaster or carousel. These rides illustrate the concept of centripetal force. We will also consider the sensation of being pulled to the outside of these rides, which we call centrifugal force.

    ## **Part A**

    Why do we experience centripetal force and acceleration on a carousel?

    15pxSpace used(includes formatting): 0 / 30000

    ## **Part B**

    Many people believe that it is centrifugal force that causes the sensation of being pulled to the outside on a carousel. What accounts for this common misconception?

    15pxSpace used(includes formatting): 0 / 30000

    ## **Part C**

    Research how a centrifuge works. Relate the mass of an object to its centripetal force, and give examples of how centrifuges are used. Include at least two authoritative research sources to support your response. Record these sources at the end of your response.
