Agas is cooled from 365 k to 285 k while its volume changes from 12.8 l to 9.9 l. the initial pressure of the gas is 1.9 atm.

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

Which best represents the law of conservation of mass ?

The slope of a velocity time graph over any interval of time gives the during that interval
