A small rock bounces off the windshield of a moving car and experiences a large change in velocity. How does the car’s momentum change?(1 point) It has a change in momentum equal to that of the rock, in the opposite direction.

It has a much smaller change in momentum than that of the rock, in the opposite direction.

It has a much smaller change in momentum than that of the rock, in the opposite direction.

It has a change in momentum greater than that of the rock, in the opposite direction.

It does not change.

Which of Newton’s laws of motion states that an object at rest stays at rest and an object in motion stays in motion with the same speed and the same direction unless acted upon by an unbalanced force?(1 point)

Newton’s third law of motion

Newton’s second law of motion

Newton’s fourth law of mo

What is magnetic flux? explain faraday's law of induction.

1. consider the case in which air fills air shocks on a truck trailer. the pressure in the shocks is 2 mpa. the temperature is 300 k. the diameter of the shock piston is 10 cm and the initial length of the cylindrical cavity containing the compressed air is 40 cm. a. the truck is gradually loaded over a period of a day in a static setting. the temperature is held constant for the atmosphere and thus for the gas shock. calculate the compressibility of the air in the shock for this condition when the truck is initially being loaded. b. if the shocks were loaded in a dynamic setting by driving over bumps, what would be the compressibility? state your assumption. c. what is the initial load on the shock if the shock is in an atmospheric 100 kpa? d. if the shock is compressed using the process described in part a, and the air shock compressed air cavity length decreases to 20 cm, what is the additional load applied to the shock?
