An object of the same mass has three different weights at different times. Which statement is possible?
The object gains matter and then loses it.
The object started on Earth, was transported to space, and was deposited on the moon.
The object started at the bottom of a hill, then moved to the top of the hill, and then moved back down to the bottom of the hill.
The object changes shape, which changes its weight.

Engines for propeller-driven aircraft are limited in their maximum rotational speed by the fact that the tip speed of the propeller must not approach the speed of sound in air (mach i). taking 6 ft as a typical diameter for a propeller of a light airplane and 1100 fils as the speed of sound, find the upper limit on the rpm (revolutions per minute) of the propeller shaft.
