Question

Any 4 important of pressure

Answer 1

Answer:

1. In knives

2. In Syringes

3. In Studs

4. In Skis

Explanation:

1. The area of the edge of a knife's blade is extremely small. This creates a pressure high enough for the blade to cut through a material.

2. Syringes are used to take blood for blood tests. The pressure of the liquid (blood) forces it to move into the syringe when it's plunger is withdrawn.

3. The pressure under the studs on the soles of football shoes is high enough for them to sink into the ground, which gives extra grip.

4. Skis have a large area to reduce the pressure on the snow. This ensures that the skis do not sink into the snow.
