Question

Explain why life belts and buoys are used by swimmers to float

Answer 1

Anything with its Density lighter than that of water can float on it.

• The Life Belts and Buoyas use the same principle.

• They are filled with AIR which makes their density soo much less than water .

• So that even if Heavy Weights (Human Beings) can't increase its density more than water,which in turn, help swimmers to Float on Water.
