Question
One end of a cylindrical rod is kept in steam chamber and the other end in melting Ice. Now 0.5 gm of ice melts in 1 sec. If the rod is replaced by another rod of same length, half the diameter and double the conductivity of the first rod, then rate of melting of ice will be
- 0.25gm/sec
- 0.5gm/sec
- 1gm/sec
- 2gm/sec
The correct answer is: 0.25gm/sec

By observing an alternating Doppler shift of a spectral line, the astronomers can deduce the existence of a binary star system, which otherwise cannot be resolved visually. Suppose that an astronomical observation shows that the source of light is eclipsed once every 18h. The wavelength of the spectral line observed changes for a maximum of 563 nm to a minimum of 539 nm. Assume that the binary system consists of two identical stars. Determine the mass of each object.

has a circular running track of radius a/2 with its centre coinciding the centre of the ground. A man is running on the track with an angular velocity 
while a car is moving on a road adjacent to ground as shown in the figure. The car moves in such away that the car, the man and the centre of the ground always lie on the same straight line. If a source of sound of frequency v=300 Hz is being placed at the centre of the ground find the minimum frequency received by the man in the car. Assume velocity of sound in air is v=330 m/s.
