Yes, and please specify what kind of power source I should use. Is a 9-volt battery enough? How about three button cells?

I am supposed to make an open circuit and let the current pass through the body in order to close it. I do not know which is appropriate: 9-volt battery powering a buzzer OR three button cells powering LEDs.

I am afraid of giving myself an electric shock though; I do wish to be careful at least.

A spring used in an introductory physics laboratory stores 14 J of elastic potential energy when it is compressed 0.20 m. Suppose the spring is cut in half. When one of the halves is compressed by 0.20 m, how much potential energy is stored in it?

Somewhere between the earth and the moon, gravity from these two bodies on a space pod would cancel. Is this location nearer to the earth or to the moon?
2.- SECOND PROBLEM
The earth and the moon are atracted to each other by gravitational force. Does the more massive earth attract the less massive moon with a force that is greater, smaller, or the same as the force with which the moon attracts the earth?.

PLEASE SPECIFY WHICH ANSWER IS FOR WHAT QUESTION

So, I want a 15amp circuit breaker on the headlights of my vintage car (12 volt). I have two 7.5 amp circuit breakers. I could put one circuit breaker on each headlight, but what would happen if I wired the two circuit breakers together in parallel? Could I draw 15amps through the pair of them, or would they trip at 8amps?

Finally, and just out of interest, if you wired a 10amp breaker and aa 5 amp breaker together in parallel, when would they trip?
