A bird flies for `4 s` with a velcoty `v=t (-2) ms^(-1) in a stralght line. Calculate the displacement of the bird ans distance travelled by the bird.

A bird flies for 4s with a velocity V=(t-2) m//s in a straight line where t= time in second Calculate the displacement and distance covered by the bird

A bird flies for 4s with a velocity V=(t-2) m//s in a straight line where t= time in second Calculate the displacement and distance covered by the bird

A bird flies for 4 sec with a velocity of |t-2| m/s in a straight line, where t= time in seconds. It covers a distance of :

A bird flies for 4 seconds with a velocity of |t-2|m//sec. In a straight line, where t= time in seconds. It covers a distance of

A bird flies for 4s with a velocity of |t-2| m/s in a straight line, where time, t in seconds. It covers a distance of

A bir is singing on a tree and a man is hearing at a distance r from the bird. Calculate the displacement of the man towards the bird so that the loudness heard by man increases by 20dB . [Assume that the motion of man is along the joining the bird and the man].

A bird in air looks at a fish directly below it inside in a transparent liquid in a tank. If the distance of the fish as estimated by the bird is h_1 and that of the bird as estimated by the fish is h_2, then the refractive index of the liquid is
