An astronaut experiences a gravitational field strength of 9.60 N/kg. The distance between Earth's surface and the astronaut is km. (Record your three-digit answer on the answer sheet.) Answer: A newly discovered planet, 581c, has a mass that is five times greater than Earth's mass and a diameter one and a half times larger. If Earth's gravitational field strength is 9.81 N/kg, planet 581c's gravitational field strength is _N/kg. (Record your three-digit answer on the answer sheet.) Answer: Which of the following statements concerning true weight, , and apparent weight, w, are correct for a person in an elevator? If the elevator is at rest or moving up or down at constant speed, the person has an apparent weight equal to her true weight. If the elevator is moving up with decreasing speed or moving down with decreasing speed, the person has an apparent weight less than her true weight. 111 If the elevator is moving down with decreasing speed or moving up with increasing speed, the person has an apparent weight larger than her true weight.
