Question # 1

Define elasticity and stress

Ans 1: Density: Density of a substance is defined as its mass per unit volume.
Unit: SI unit of density is kilogram per cubic metre
Ans 2: Formula: density= Mass of substance/Volume of that substane
Ans 3: Density of gold: The value of density of gold is
Elasticity: Elasticity is the property of a body to restore it original size and shape as the deforming force ceases to act is called elasticity.
TStress: The force acting on unit area at the surface of a body is called stress
Ans 4: Formula: stress= force/Area
Ans 5: Unit: in SI the unit of stress in Newton per square meter

Question # 1

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

Ans 1: Submarine floats over water when the weight of the water equal to its volume is greater than its weight Under this condition it is similar to a ship and remain partially above water level When the tanks of submarine are filled the weight of the submarine increases. As soon as its weight becomes greater than the upthrust, it dives into water and remains under water To comes up on the surface the tanks re emptied from seawater.
