Question

WHEN WE STAND NEAR A RAILWAY TRACK AND A TRAIN PASSES BY AT HIGH SPEED U FIND PAPER AND BITS OF CLOTH FLYING WITH IT.GIVE A REASON FOR THIS

Answer 1

As train passes with high speed it creates a low pressure area as pressure is inversely proportional to velocity.so due to pressure difference the wind flows frm high pressure region to low pressure region and hence the blowing wind take the light weighted objects such as pieces of cloth and paper with it.
