Two friends A and B are standing a distance x apart in an open field and wind is blowing from A to B.A beats a drum and B hears the sound `t_1` timed after he sees the event. A and B interchange their positions and the experiment is repeated. This time B hears the drum `t_2` time after he sees the event. Suppose A and B in the previous problem change their positions in such a way that the line joining them becomes perpendicular to the direction of wind while maintaining the separation x. What will be the time lag B finds betweenseeing and hearing the drum beating by A?

Two friends A and B are standing a distance x apart in an open field and wind is blowing from A to B. A beats a drum and B hears the sound t_1 timed after he sees the event. A and B interchange their positions and the experiment is repeated. The velocity of sound in still air is v and the velocity of wind is u . This time B hears the drum t_2 time after he sees the event. Suppose A and B change their positions in such a way that the line joining them becomes perpendicular to the direction of wind while maintaining the separation x . What will be the time lag B finds between seeing and hearing the drum beating by A?

Two friends A and B are standing a distance x apartin an open field and wind is blowing from A to B.A beats a drum and B hears the sound t_1 timed after he sees the event. A and B intechange their positions and te experiment is repeated. This time B hears teh drum t_2 time after he sees the event. Calculte teh velocity of sound in still air v and the velocity of wind u. Neglect the tiem light takes in travelling between the friends.

Two friends A and B are standing a distance x apart in an open field and wind is blowing in a direction perpendicular to .the line joining AB. A beats a drum and finds a time lag between seeing and hearing the drum beating by A. Find this time lag.

Suppose A and B are two events.Event B occurred and it is known that P(B)<1

A coin is tossed three times. Event A: two heads appear Event B: last should be head Then identify whether events A and B are independent or not.
