A person is pushing a cart with a force of 12 newtons causes an acceleration of 0.6 m/s/s. What must the mass of the cart be?

How would a small bar magnet be oriented when placed at position x?

If y gets smaller as x gets bigger and y have an relationship?

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
