When a 219.39-kg crate is pulled across a frictionless horizontal floor with a force of 800 N, directed 30° above the horizontal, the magnitude of the normal force of the floor on the crate is:a. 1560 Nb. 380 Nc. 680 Nd. 580 Ne. 1750 N

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

In order to do work, the force vector must be question 1 options: in a different direction than the acceleration vector. in a different direction than the displacement vector. in the same direction as the displacement vector and the motion. in the same direction as the acceleration vector.
