A travelling wave passes a point of observation. At this point, the time interval between successive crests is 0.2 seconds and

Time interval between two successive heart beat is in the order of ……………

What is the time interval between two successive tides at a given place on the earth?

What is the phase difference between two successive crests in the wave

Mean solar day is the time interval between two successive noon when sun passes through zenith point (meridian). Sidereal day is the time interval between two successive transit of a distant star through the zenith point (meridian). By drawing appropriate diagram showing the earth's spin and orbital motion, show that mean solar day is 4 min longer than the sidereal day. In other words, distant stars would rise 4 min early every successive day.

If a satellite is travelling in the same direction as the rotation of earth i.e., west to east, what is the interval between two successive times at which it will appear vertically overhead to an observer at a fixed point on the equator? (R = 6400 km, h = 1400 km)

A satellite revolves in the geostationary orbit but in a direction east to west. The time interval between its successive passing about a point on the equator is:
