Instead nick hands the rope with the scale to his friend barney, who stands on the ground. barney pulls on the rope so that the spring scale again reads 320 n. what is nick's acceleration now, again using upward as positive.

True or false graphs must include scales that increase by the same amount

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.
