A person can jump to a height of 3 m at the equator of the Earth. Considering the same initial velocity for jumping, to what height can he jump at the poles? The radius of the Earth at the poles and the equator is 6357 km 6378 km, respectively. Given, (6357)/(6378) = 0.9967

A man at the bottom of a pool wants to signal to a person lying at the edge of the pool. The man should beam his water proof light ___________ .

A boy standing on a weighing machine notices his wight as 400 N. When he suddenly jumps upward the weight shown by the machine becomes 600 N. The acceleration with which the boy jumps up is : (Take g=10m//s^(2) )

A circular swimming pool is surrounded by a concrete wall 4m wide. If the area of the concrete wall surrounding the pool is (11)/(25) that of the pool, then the radius (in m) of the pool is :

The maximum vertical distance through which a fully dressed astronaut can jump on the earth is 0.5 m . If mean density of the Moon is two-third that of the earth and radius is one quarter that of the earth, the maximum vertical distance through which he can jump on the Moon and the ratio of the time of duration of the jump on the Moon to hold on the earth are
