When 5.30* 10^5 J of heat is added to a gas enclosed cylinder fitted with a light frictionless piston maintained at atmospheric pressure, the volume is observed to increase from 1.9 m^3 to 4.1m^3. Calculate
a) the work done by the gas, and
b) the change in internal energy of the gas.
c) graph this process on a PV diagram.
An 8-g bullet is fired into a 170 g block that is initially at rest at the edge of a table of 1m height. The bullet remains in the block, and after the impact the block lands d = 2.10 m from the bottom of the table. Determine out the initial speed..
