One-half mole of a monatomic ideal gas expands adiabatically and does 520 J of work.
(a) By how many kelvins does its temperature change?
(b) Specify whether the change is an increase or a decrease.
A stone is shown at rest on ground. at. The vector shows the weight of the stone. Complete vector diagram showng another tha results in zero net force on the stone. b. What is the conventional name of the vector you have drawn.
An event occurs at x′ =60m, t′ =8×10-8 sec in a frame S′ (with y′ =0, z′ = 0). The frame S′ has a speed of 3c/5 in the x direction with respect to frame S. The origins of S and S′ coincide at t = 0, t′ = 0. What are the spacetime coordinates of th..
