In other words it is the angle which the line joining the observer and the sum makes with the horizontal. It us used by sailors Why does the specific gravity of milk increase, when cream is removed http://www.allinterview.com/showanswers/21055.html The cream has a lower specific gravity(density) than milk and density of a mixture depends upon its constituents, depending upon their relative proportions. A decrease on the proportion of lighter constituent will result in the increase of the sp Why is it easier to swim in sea water than in the river water? http://www.allinterview.com/showanswers/21023.html It us easier to swim in sea water than in river water, because sea water is denser than river water and the body sinks less in it Explain the Real and Virtual Image ? http://www.allinterview.com/showanswers/21556.html When a pencil of ray, diverging from a point, after reflection and refraction, actually passes through a second point that second point is called the real image of the first point. When a pencil of rays after reflection; and refraction only ap Why do we not feel the enormous weight of the atmosphere above our he http://www.allinterview.com/showanswers/21038.html We do not feel the enormous weight of the atmosphere above our heads, because the pressure is same on all the sides. What is the normal pulse beat of a human body? http://www.allinterview.com/showanswers/21135.html 78 beats per minute. How does the electricity travel ? http://www.allinterview.com/showanswers/21133.html It travels in wires of metal by conduction, in solutions by a kind of connection and through space by radiation. Explain the Reflection of Light ? http://www.allinterview.com/showanswers/21555.html The point where a ray of light strikes the surface of a mirrors is called the point of incidence. If a normal is drawn to the surface at this point, the angle4 which the incident ray makes with it is called the angle of incidence. The angle name of the ten satellite launched from india and year of launch. http://www.allinterview.com/showanswers/77020.html 1. Aryabhata(1975) 2. Bhaskara-I(1979) 3. Bhaskara-II(1981) 4.

Explain the refraction of light ? http://www.allinterview.com/showanswers/21557.html Refraction:-When a pencil of light passes obliquely from one transparent medium into another, it undergoes some deflection from its straight path. This change in direction is called refraction Law of Refraction:- 1. The incident ray the refr
