The Change mass of fuel during a nuclear reaction
is 2.0 x 102kg calculate the
amount of energy released.
I speed of light = 2.0x108mg)

2kg of refrigerant 134a undergoes a polytropic process in a piston-cylinder assembly from an initial state of saturated vapor at 2 bar to a final state of 12 bar, 80 degree c. a)determine the work for the process in kj. b)sketch the process on a p-v diagram.

The diagram shows four locations in the electric field of a positive point charge m. at which location is the electric potential the greatest.

What sort of waves exhibit the doppler effect?
