A sample of gas with $$\gamma$$ = 1.5 is taken through an adiabatic process in which the volume is compressed from 1200 cm³ to 300 cm³. If the initial pressure is 200 kPa. The absolute value of the workdone by the gas in the process = _____________ J.

At very high frequencies, the effective impendence of the given circuit will be ________________ $$\Omega$$.

Cross-section view of a prism is the equilateral triangle ABC in the figure. The minimum deviation is observed using this prism when the angle of incidence is equal to the prism angle. The time taken by light to travel from P (midpoint of BC) to A is ______________ $$\times$$ 10^$$-$$10 s. (Given, speed of light in vacuum = 3 $$\times$$ 10⁸ m/s and cos30$$^\circ$$ = $${{\sqrt 3 } \over 2}$$)

A resistor dissipates 192 J of energy in 1s when a current of 4A is passed through it. Now, when the current is doubled, the amount of thermal energy dissipated in 5s in _________ J.
