Four gram-moles of an ideal monatomic gas initially at temperature 300 K is compressed adiabatically from a volume of 1200 cm3 to a volume of 350 cm3.
a) How much heat was transferred to the gas?
b) What is the final temperature of the gas?
c) What is the work done by the gas?
A 2.30 cm diameter tungsten sphere is heated to a temperature of 2000 degree C. At this temperature tungsten radiates only 30% of the energy radiated by a blackbody of the same size and temperature.

In a certain RLC circuit, the RMS current is 6.42 A, the RMS voltage is 235 V, and the current leads the voltage by 55.6°. Calculate the average power dissipated in the circuit
Consider a disk of radius R = 41.0 cm and thickness t = 1.1 cm, with a nonuniform volume charge density given by ? = A, If A = 510 ?C/m4, what is the total charge of this disk
A spotlight is coated so that it won't transmit magenta light from its white-hot filament. What colour emerges from coated spotlight.
A positive charge of 0.800? C is located in a uniform field of 1.20×105 N/C. A negative charge of -0.400? C is brought near enough to the positive charge that the attractive force between the charges just equals the force on the positive charge du..
