A man is standing on incline which makes `theta` with horizontal and rain is falling vertically with respect to man. Now man starts walking along the incline. Mark the correct option

A

If man walks up the incline, rain may appear to come horizontally

B

If man walks down the incline, rain may appear to come horizontally

C

No matter whether man walks up or down, rain can never appear to come horizontally.

D

If man walks (up or down) along incline rain may appear to come along the incline.

A man is standing on a road and observes that rain is failing at angle 45^(@) with the vertical. The man starts running on the road with constant acceleration 0.5m//s^(2) . After a certain time from the start of the motion, it appears to him that rain is still falling at angle 45^(@) with the vertical, with speed 2sqrt(2)m//s . Motion of the man is in the same vertical plane in which the rain is falling. Then which of the following staement(s) are true.

When a man moves down the inclined plane with a constant speed 5 ms^-1 which makes an angle of 37^@ with the horizontal, he finds that the rain is falling vertically downward. When he moves up the same inclined plane with the same speed, he finds that the rain makes an angle theta = tan^-1 (7/8) with the horizontal. The speed of the rain is
