Abicycle tire has a pressure of 7.00×105 n/m2 at a temperature of 18.0ºc and contains 2.00 l of gas. what will its pressure be if you let out an amount of air that has a volume of 100cm3 at atmospheric pressure? assume tire temperature and volume remain constant.

Afeather of mass 0.001 kg falls from a height of 2 m. under realistic conditions, it experiences air resistance. based on what you know about friction, what can you say about the kinetic energy of the feather as it reaches the ground? acceleration due to gravity is g = 9.8 m/s2. a. ke < 0.0196 j b. ke = 00196 j c. je = 0 j d. ke > 0.0196 j
