What is the specific latent heat of a
0.75kg object that transfers 251kJ during a change of state?

During the power stroke of an engine, the work produced is 2520 kj/kg and the heat rejected through the cylinder is 570 kj/kg. If the internal energy increased by 120 kj/kg, determine the amount of heat received in kj/s if the working fluid flow at the rate of 3 kg/s.

) Given, E ̅ = E ̅m sin(x) sin (t) a ̂y and H ̅ = E ̅m/µo cos(x) cos (t) a ̂z. Determine whether these fields satisfy Maxwell’s equations or not.

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

Find the steady-state temperature in a bar whose ends are located at x = 0 and
x = 15, if these ends are kept at 200°C and 100°C respectively. (Use Fourier series)
