A5.0 kg dog sits on the floor of an elevator that is accelerating downward at 1.20 m/s^2 .?
a) what is the magnitude of the normal force of the elevator floor on the dog?

b) what is the magnitude of the force of the dog on the elevator floor?

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
