explain molar specific heat.

A runner starts from rest and accelerates uniformly to a speed of 8.0 meters per second in 4.0 seconds. What is the magnitude of the acceleration of the runner?

A frictionless piston is used to provide a constant pressure of 400 kPa in a cylinder containing steam originally at 200 degree C with a volume of 2 m3. If 3500 kJ of heat is added.Calculate the final temperature

A moving train travels through station P with a speed of 20 meter per seconds anf accelerate uniformly for 2 seconds reaching a speed of 48 meter per second, it continue with this speed for 5 seconds and then retardate uniformly for another 3 seconds and comes to rest at station Q. Find the distance from P to Q
