an ideal gas at 75.0 c and 760 .mm hg is contained in a flexible vessel. Its volume is doubled and the pressure remains.unchanged .determine the temperature of the gas as a consequence of these changes

5. What is the acceleration of a 20 N object that is pulled up a 30° incline by a 25 N force? The coefficient of friction is 0.30

1. A man pulls a 300 N object across a horizontal surface using a 100 N force applied at a 35° angle. What is the normal force? If the object is pulled at constant speed, what is the coefficient of friction

2. A 10 N object rests on a 10° incline. What is the normal force? What is the parallel force? A 10 kg object rests on a 10° incline. What are the normal and the parallel forces

3. A 5 N block slides down a 20° incline at constant speed. What is the frictional force?

4. What force is needed to push a 15 N object up a 20° incline at constant speed when the coefficient of friction is 0.30
