Question

give an experiment to show that increased wind speed is accompanied by reduce air pressure​

Answer 1

Answer:

Explanation:

Crumple a small piece of paper into a ball of smaller size than the mouth of an empty bottle.

Hold the empty bottle on its side and place the paper ball just inside its mouth.

Now try to blow on the ball to force it into the bottle.

When we blow into the mouth of the bottle the air near the mouth has higher speed. This decreases the pressure there. The air pressure inside the bottle is higher than near the mouth. The air inside the bottle pushes the ball out.
