1.) Compare the magnitude of Earth's rotational momentum about its axis to that of the Moon about Earth. The period of the Moon's rotation about Earth is 29.5 days, the mass of the Moon is 7.35×10^22kg, the radius of the Moon's orbit is 3.84×10^8m, Earth's mass is 5.98×10^24kg, and Earth's radius is 6370 km. Lm/Le=?

2.) The tides exert a torque on Earth and Moon so that eventually they rotate with the same period. The object with the greatest rotational momentum will experience the smallest percent change in the period of rotation. Will Earth's solar day increase more than the moon's period of rotation decreases?
(A.) Earth's solar day increases more than the moons period of rotation decreases by the tidal effect.
OR
(B.) Earth's solar day increases less than the moons period of rotation decreases by the tidal effect.

An astronaut in space cannot use a scale or balance to weigh objects because there is no gravity. but she does have devices to measure distance and time accurately. she knows her own mass is 77.4 kg , but she is unsure of the mass of a large gas canister in the airless rocket. when this canister is approaching her at 3.50 m/s , she pushes against it, which slows it down to 1.30 m/s (but does not reverse it) and gives her a speed of 2.60 m/s . what is the mass of the canister?
