Assuming that voltage remains constant, what happens to the current in a wire if the length of the wire decreases?

Aplane travels 1000 miles in 5 hours .what is the planes average speed?

If jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, is being done.

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e
