Question

which of the two is accompanied with high speed winds reduced air pressure or increased air pressure?

Answer 1

Dear Student ,
When we blow air into the bottle , the air near the mouth has higher speed . This decrease the pressure there .
The pressure of air inside the bottle is more than the pressure near the mouth . Therefore , the air inside the bottle pushes the ball out. This is the experiment about high speed winds are accompanied by reduced air pressure .
