Amass is set oscillating horizontally, with an amplitude of 11.3 cm and a period of 0.702 sec. what is the velocity of the particle when the position is 1/2 the amplitude in the positive x direction and moving toward x=0?

Aforce of 200 n is applied to an input piston of cross-sectional area 2 sq. cm pushing it downward 2.8 cm. how far does the output piston of cross-sectional area 12 sq. cm move upward? show all work.

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

The diagram shows four locations in the electric field of a positive point charge m. at which location is the electric potential the greatest.
