• 49-N block is pulled by a horizontal force of 50.0 N along a rough horizontal surface at a constant acceleration of 6 m/s². What is the coefficient of friction? Explain your answer.

The speed of light can be used to measure the

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

Acar travels in reverse. it covers 150 meters in 12 seconds what is the velocity of the car what is the speed of the car
