2. A compressed gas is held inside a canister with a moveable lid. The temperature of the gas is significantly higher than the air temperature outside the canister. When weight is removed from the lid, the gas
expands to lift it. For this expansion to be as nearly adiabatic as possible, which condition should be met?

Two particles of masses m and 2m are placed on a smooth horizontal table. a string, which joins these two masses, hangs over the edge supporting a pulley, which suspends a particle of mass 3m. the pulley has negligible mass. the two parts of the string on the table are parallel and perpendicular to the edge of the table. the hanging parts of the string are vertical. find the acceleration of the particle of mass 3m.

Which two objects have the greatest gravitational force acting between them

Acoyote chasing a rabbit is moving 8.00 m/s due east at one moment and 8.80 m/s due south 4.25 s later. let the x axis point due east and the y axis point due north. find the direction of the coyote's average acceleration during that time.
