Asap need right answer

why do a car's tires need more air in the winter than they do in the summer?

the temperature is lower, so the tires expand

the temperature is lower, so the tires contract

the temperature is lower, so the air inside the tires expands

the temperature is lower, so the air inside the tires contracts

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 10.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.90 m/s; (b) he is then lifted at the constant speed of 4.90 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 68.0 kg rescue by the force lifting him during each stage?
