QUESTION 34
An astronaut on the Moon simultaneously drops a feather and a hammer. The fact that they land together shows that:
OA. the feather has a greater weight on the Moon than on Earth
B. no gravity forces act on a body in a vacuum
OC. in the absence of air resistance all bodies at a given location fall with the same acceleration
OD.G=0 on the Moon
OE. the acceleration due to gravity on the Moon is less than g on the Earth
QUESTION 35
Mars has a mass of about 0.1075 times the mass of Earth and a diameter of about 0.533 times the diameter of Earth. The acceleration of a body falling near the surface of
Mars is about:
OA 2.0 m/s²
OB 1.4 m/s2
OC-0.30 m/s²
OD-26 m/s²
OE. 3.7 m/s²

QUESTION 36
In deep space, sphere A of mass 140 kg is located at the origin of an x axis and sphere B of mass 130 kg is located on the axis at x = 8.3 m. Sphere B is released from rest
while sphere A is held at the origin. What is the gravitational potential energy of the two-sphere system just as B is released?
(Gravitational constant = 6.67408 × 10-11 m³ kg-1 s-2)
OA.-1.46 x 10-7 J
O B.-2.34 x 10-7 J
OC.-7.17 x 10-7 J
O D.-3.90 x 10-7 J
O E.-4.11 x 10-7 J
