1. A child standing on a bus remains still when the bus is at rest. When the bus moves
forward and then slows down, the child continues moving forward at the original
speed. This is an example of
O A. an action-reaction pair.
OB. Newton's First Law of Motion.
O C. Newton's Second Law of Motion.
O D. Newton's Third Law of Motion.

Using software, a simulation of a javelin being thrown both on earth and on the moon is created. in both cases, the velocity and angle of projection are kept the same. on earth, the javelin covers a distance y. what distance would it cover on the moon? (the moon’s gravity is about 1/6th that of earth.) a. 6y b. 6/y c. y/6 d. (y+6)2

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 force it would take to accelerate an 900-kg car at the rate of 6m/s2
