A ball is dropped from top of a tower of 100 m height. Simultaneously another ball was thrown upward from bottom of the tower with a speed of 50 m/s. They will cross each other after (g = 10 m/s\(^2\))

The driver of a car moving towards a rocket launching pad with a speed of 6 m/s observes that the rocket is moving with speed of 10 m/s. The upward speed of the rocket as seen by the stationary observer is

A satellite revolves very near to the earth surface. Its speed should be around

If the density of earth is doubled keeping its radius constant, then acceleration due to gravity g is

When a copper sphere is heated, percentage change is

Three identical thermal conductors are connected as shown in figure. Considering no heat loss due to radiation, temperature at the junction will be

r

Two bodies A and B having temperatures \( 327^\circ C \) and \( 427^\circ C \) are radiating heat to the surrounding. The surrounding temperature is \( 27^\circ C \). The ratio of rates of heat radiation of A to that of B is
