Description

John Wiley & Sons, Inc. has created a set of Java applet-based Physics Simulations in WebAssign. These questions are freely available to anyone using a Wiley Textbook. Click here for a list of all of the questions coded in WebAssign.


Instructions

This demo assignment allows many submissions and allows you to try another version of the same question for practice.

AC Circuit with only One Circuit Element

(a) Given the limits on the sliders available to you in the simulation, what are the maximum and minimum values of the "Maximum current" that can be obtained in the simulation?

The maximum possible "Maximum current" is

Enter a number.
A.

The minimum possible "Maximum current" is

Enter a number.
A.

(b) Which of the following will always result in increasing the "Maximum current" value in an AC Circuit with only one circuit element? Select all that apply.



(c) You have either a resistor, a capacitor, or an inductor connected to an AC source. As you increase the frequency of the voltage you notice that the maximum current increases linearly with frequency. What, if anything, can you conclude about what you have connected to your AC source?

Mass on a Spring

After running the simulation press the Reset button to activate the sliders. To get the total energy graph to display correctly after changing the initial velocity, hit the Reset button again.

First experiment with the simulation to see what effect changing the initial velocity and the mass has on the motion. Then consider the following four cases, which differ in the settings used in the simulation above:

Case A: Initial velocity = +v; Mass = m
Case B: Initial velocity = -v; Mass = m
Case C: Initial velocity = 0; Mass = m
Case D: Initial velocity = +2v; Mass = m

Predict the results of the questions below, and then use the simulation to verify your predictions.

(a) Rank these cases based on the oscillation amplitude, from largest to smallest (use the notation > or =, for example A>B=D>C).

Answer is not case sensitive.

(b) Rank these cases based on the time (after t=0) the mass first passes through the equilibrium position, from longest time to shortest time (use the notation > or =, for example A>B=D>C).

Answer is not case sensitive.
