1. A battery is manufactured to have and emf of 24V, but the terminal voltage is only 22V when the battery is connected across a 7.5ohm resistor...what is the internal resistance of the battery?
3. Ok I have the answer already which is .68ohm...but I can't find a way to get to it. At...

3. Here is my attempt:
First I figure I have to find the deceleration of the particle. So I plugged it into the v(final)^2= v(initial)^2 + 2ax. I solved for a and got a and got -240000.
I don't know if I am...

2. As you can see I already have the answers, I think I'm just doing something wrong.
3. I already know that the answer will be 'away' making it either a or c. So first I plugged the equation given (f1 =...

2. As you can see the answers are already available, I'm just having trouble trying to get to them.
3. For number 4 I've tried plugging in the k value (8000) and distance (.05) into get a force value...
