Question

Explain in short :-

(a) Atmoshperic Pressure
(b) Liquid Pressure
(c) Relative Density

(d) Horse Power
(e) Density
(f) Energy conservation

(g) Alternative sources of energy​

Answer 1

Answer:

(a) Atmospheric pressure is a force in an area pushed against a surface by the weight of the atmosphere of Earth, a layer of air.

(b) Liquid pressure is the increase in pressure at increasing depths in a liquid.

(c) Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material.

(d) Horsepower, the common unit of power; i.e., the rate at which work is done. In the British Imperial System, one horsepower equals 33,000 foot-pounds of work per minute—that is, the power necessary to lift a total mass of 33,000 pounds one foot in one minute.

(e) Density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume.

(f) Energy conservation is the effort made to reduce the consumption of energy by using less of an energy service.

(g) Alternative energy generally refers to any group of non-traditional fuel sources that does not burn fossil fuels or use up any type of natural resources which will result in damage or harm to the environment.

Answer 2

Atmospheric pressure the pressure exerted by the atmosphere is called atmospheric pressure

Pressure exerted by liquid is known as liquid pressure

Density is the determination of how closely packed The atoms in a particular substance

Conservation of energy or saving of energy is known as energy conservation
