Horizontal forces act on two boxes, initially at rest, as shown. The magnitude and direction of horizontal forces are also shown. What happens to box X and box Y as a result of the forces?

• Box X starts moving, speeding up, Box Y remains at rest.

• Box X starts moving at a constant speed, and Box Y remains at rest.

• Box X starts moving at a constant speed, and Box Y starts moving, speeding up.

• Box X starts moving, speeding up, Box Y starts moving at a constant speed.

Two positively charged particles are attached to springs. A metal sphere is placed near each charged particle, as shown in the diagram. Positive charge is slowly added to sphere A. An equal amount of negative charge is slowly added to sphere B. Assume the two systems are isolated from each other. How does the elastic potential energy change for each of the springs?

• The elastic potential energy of both springs will increase.

• The elastic potential energy of both spring will decrease.

• The elastic potential energy of the spring in set-up A will decrease and the elastic potential energy of the spring in setup B will increase.

• The elastic potential energy of the spring in set-up A will increase and the elastic potential energy of the spring in setup B will decrease.

An engineer is collecting data on four different satellites orbiting Earth. The engineer records the satellites' distances from Earth in kilometers (km) and their forces due to gravity in Newtons (N). Estimate the force due to gravity for satellite number 2.

• equal to 17,000 Newtons

• greater than 17,000 Newtons

• less than 17,000 Newtons
