We just started this stuff in my AP Physics class and I'm not catching on to it too quickly... At least problem solving-wise. I thought I had all the concepts down, but maybe not.
Here's a question I'm having problems with:
How do I go about this one? I'm sure it's a pretty simple problem because it's at the beginning of the chapter, but I guess I'm missing a connection or something.
Here's a question I'm having problems with:
Just as you touch a metal door knob, a spark of electricity (electrons) jumps from you hand to the knob. The electric potential of the knob is 2.0 X 10^4 V greater than that of your hand. The work done by the electric force on the electrons is 1.5 X 10^-7 J. How many electrons jump from your hand to the knob?
