Question # 1

Why does a piece of stone sink in water but a ship with a huge weight floats.

Ans 1: Ships and boats float on water because the weight of an equal volume of water is greater than the weight of ships and boats. A stone sinks in water because the weight of an equal bolume of water is smaller than the weight of stone.

Question # 1

What is atmospheric pressure? How can we measure the atmospheric pressure?

Ans 1: Atmospheric Pressure:
The earth is surrounded by a cover of air is called atmosphere. It extends to a few hundred kilometers above sea level. Just as certain sea creature live at the bottom of ocean, we live at the bottom of a huge ocean of air.Air is the mixture of gases.
The density of air in the atmosphere is not uniform . It decreases continuously as we go up.

Question # 1

Differentiate between strain and tensile srain.

Ans 1: Tensile strain: A comparison of a change caused by the stress with original length is called tensile strain. The ratio of change in length to original length is called tensile strain.
Ans 2: Formula Tensile strain= change in length/originallength
Ans 3: Unit: Strain has no units as it is simply a ratio between shape caused by the stress is called as strain.
