A Bird In Air Is Diving Vertically?

The correct options for the speed of an image of a fish as seen by a bird are A and B. A fish rising vertically with speed 3 ms to the surface of water sees a bird diving vertically towards it with speed 9 ms. Given a μ w = (4 3), the actual velocity of the dive of the bird is C.

A bird in air is diving vertically downward over a tank with speed ( 6 mathrm ~cm mathrm s) while the base of the tank is silvered. A fish in the tank is rising upward along the same line with speed 2 cms. Water level is also considered when calculating the real velocity of the diving.

A fish rising up vertically inside a pond with velocity 4 cms and notices a bird diving downward with its velocity appearing to be 16 cms (to the fish). The real velocity of the diving is found relative to the bird and the velocity.

In physics, a bird flying 3 m above the surface of water has an apparent velocity as seen by a stationary fish underwater. If the bird is diving vertically down with speed = 6 ms, his apparent velocity as seen by a stationary fish underwater is either 8 ms (B) or 6 ms (C).

A bird in air is diving vertically downward over a tank with speed 5 cms while the base of the tank is silvered. A fish in the tank is rising upward along the same line.

In conclusion, the correct options for the speed of an image of a fish as seen by a bird are A and B.
