UPDATE
Which device would cost more to run continuously for 1 hr? - ANSWER-A television that
uses a 120 V potential difference to draw 1.25 A of current
A battery connects to a resistor with resistance R, and the resulting current is
measured. The resistor is removed, and a new resistor with a resistance of 2R is added.
As a result, - ANSWER-None of the above options are correct.
Use the following voltage versus current data to determine the resistance of a particular
resistor. - ANSWER-16 Ω (rise over run with two points not the lines)
Which of the following correctly shows the equipotentials near a negative point source?
- ANSWER-C (the one that looks like a tree ring with just the circles)
A particle with a mass of 0.01 kg and a net charge of -0.05 C accelerates from rest
through a uniform electric field. If the strength of the field is 2000 V/C, what is the speed
of the particle after traveling for 0.5 m? - ANSWER-100 m/s
