Two spherical bodies A (radius 6 cm) and B (radius 18 cm) are at temperatures T1 and T2, respectively. The
maximum intensity in the emission spectrum of A is at 500 nm and in that of B is at 1500 nm. Considering
them to be black bodies, what will be the ratio of total energy radiated by A to that of B ? A stationary source is emitting sound at a fixed frequency f0, which is reflected by two cars approaching the
source. The difference between the frequencies of sound reflected from the cars is 1.2% of f0. What is the
difference in the speeds of the cars (in km per hour) to the nearest integer ? The cars are moving at constant
speeds much smaller than the speed of sound which is 330 ms–1.
