Question

When we blow over a paper strip it goes upward. Why?

Answer 1

Answer:

When we blow air above the paper strip, low pressure is created above the strip, because high speed winds are always accompanied by reduced air pressure. Therefore, because of the higher air pressure below the strip, it is pushed upwards.

Answer 2

Answer:

Coz a low area is created above the paper and high pressure is created below the paper. This high pressure pushes the paper up. when we blow above the strip the air above it gets pushed so the air below it takes place that is why the strip moves upwards. high speed winds are accompanied by low speed winds.
