Ameter stick is held vertically above your hand, with the lower end between your thumb and first finger. on seeing the meter stick released, you grab it with these two fingers. you can calculate your reaction time from the distance the meter stick falls, read directly from the point where your fingers grabbed it. if the measured distance is 18.3 cm, what is the reaction time?

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
