Question # 1

Explain how a submarine moves up the waters surface and down into water

Ans 1: Submarine can also travel over and under water, when weight of water equal to its volume is greater than its weight. Submarine has a system of tanks. When tanks are filled of sea water, weight of submarine increases, As soon as weight of submarine become greater than upthrust of water, it dives into water and remains under water

Question # 1

How the working of Hydraulic press?

Ans 1: Hydralic press is a machine which works on pascal's law.
The force F2 that acts on the larger piston is greater than the force Fq acting on the smaller piston. Hydraulic systems working in this way are known as force multipliers.

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

Show that atmosphere exerts pressure

Ans 1: The atmosphere of Earth consists of gases, vapor and dust particles. All these are material particles. Due to the force of gravity of these particles, they exert pressure. So any object inside the atmosphere experience pressure which is called the atmospheric pressure.

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.
