Question

E.) Answer briefly :
a.) Why do deep-sea divers have to wear special suits before going for diving at the depths?
b.) Why the tools meant for cutting and piercing always have sharp edges?​

Answer 1

Answer:

1.At deep waters, the column of water above the diver exerts a pressure. The pressure is very high due to the weight of water above the diver upto the surface. The diving suits are required to enable diver with stand these pressures and swim comfortably.

2.because the more the surface area the less the pressure and the less the surface area the more the pressure. We will need more pressure to cut and pierce objects that is why the tools meant for cutting and piercing have sharp edges.

Answer 2

Explanation:

A) Because the pressure of water increases with depth. so the divers wear a special type of suit to protect themselves against the pressure
