A bird is flying `3m` above the surface of water,If the bird is diving vertically down with speed `=6m//s`his apparent velocity as seen by a stationary fish underwater is:

A bird is flying 3m above the surface of water. To a fish underwater, the height of the bird from the water surface appears to be

A fish rising vertically up towards the surface of waterwith speed 3ms^(-1) observes a bird diving vertically down towards it with speed 9ms^(-1) The actual velocity of bird is (Given mu_ water =4/3

A fish rising up vertically toward the surface of water with speed 3ms^(-1) observes a bird diving down vertically towards it with speed 9ms^(-1) . The actual velocity of bird is

A fish rising up vertically toward the surface of water with speed 3ms^(-1) observes a bird diving down vertically towards it with speed 9ms^(-1) . The actual velocity of bird is

A fish rising up vertically toward the surface of water with speed 3ms^(-1) observes a bird diving down vertically towards it with speed 9ms^(-1) . The actual velocity of bird is

A swimmer is diving in a swimming pool vertically down with a velocity of 2 ms^(-I) . What will be the velocity as seen by a stationary fish at the bottom of the pool right below the diver? Refractive index of water is 1.33

In a lake, a fish rising vertically to the surface of water uniformly at the rate of 3 m/s, observes a bird diving vertically towards the water at the rate of 9 m/s. The actual velocity of the dive of the bird is (given, refractive index of water = 4/3)

In a lake, a fish rising vertically to the surface of water uniformly at the rate of 3 m/s, observes a bird diving vertically towards the water at the rate of 9 m/s. The actual velocity of the dive of the bird is (given, refractive index of water = 4/3)
