14g of nitrogen gas at 0°C and 1 atm is compressed in an isochoric process to an pressure of 20 atm.
a) What is the final temperature of the gas?
b) What is the work done on the gas?
c) How much heat is inputted into the gas?
d) Show the process in a p-V diagram
A baseball pitcher throws a fastball at a speed of 45.00m/s. The acceleration occurs as the pitcher holds the ball in his hand and moves it throughout an almost straight-line distance of 4.0 m. compute the acceleration; assume that it is constant ..
