← Suppose the Earth spun faster and faster about its axis. Things at the equator would weigh less and less, because more of gravity's pull would be used to keep them moving in their circle. Taking the Earth's radius as 6400 km and g = 10 m/s², how long would a day have to be for objects at the equator to feel weightless?One mole of an ideal monatomic gas at temperature T₀ expands adiabatically (no heat in or out) until its volume is 8 times larger. Its final temperature, and the work done by the gas, are →
