Let omega be a complex cube a root of unity with omega != 1 . A fair die is thrown three times . If r_(1),r_(2) and r_(3) are the numbers obtained on the die , then the probability that omega^(r_(1))+omega^(r_(2))+omega^(r_(3))= 0 is :

In changing the state of a gas adiabatically from an equilibrium state A to another equilibrium state B, an amount of work equal to 22.3 J is done on the system. If the gas is taken from state A to B via a process in which the net heat absorbed by the system is 9.35 cal, how much is the net work done by the system in the latter case ? (Take 1 cal = 4.19 J)
