Air containing gasoline vapor is admitted into the cylinder of an internal combustion engine at 1.00 atm pressure and 30 °C. The piston rapidly compresses the gas from 500 cm3 to 50 cm3, a compression ratio of 10. This type of compression is too rapid for heat to be transferred from the gas to the environment, so it can be modeled as an adiabatic compression. (a) What are the final temperature and pressure of the ? (b) Show the compression process on a pV diagram. (c) How much work is done to compress the gas? [air is a mixture of N2 and O2, diatomic gases, so use yair 1.4 L7. as 0]

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j

Give me some answer choices and i will be happy to

How are period and frequency related to each other? dperiod is the reciprocal of frequency.
