a cylinder of gas has a Mass of 10kg and a pressure of 8 atm at 27°C when some gas is used in Cold room at –3°C the gas remaining in the cylinder at this temperature has a pressure of 6.4 atm calculat the Mass of gas used.​

Spend time observing or thinking about events that involve matter and energy. which events can you explain? which events can’t you explain?

You are traveling in a car going at a constant speed of 100km/h down a long, straight highway. you pass another car going in the same direction which is traveling at a constant speed of 80km/h. as measured from your car's reference frame this other car is traveling at −20km/h. what is the acceleration of your car as measured from the other car's reference frame? what is the acceleration of the other car as measured from your car's reference frame?

The system is released from rest with the cable taut, and the homogeneous cylinder does not slip on the rough incline. determine the angular acceleration of the cylinder and the minimum coeffi cient s of friction for which the cylinder will not slip.
