It can be proved by an experiment given below. Arrange two pieces of cardboard, having pin holes at the centre of each, vertically, one behind the other. They should be arranged in What is Sextent ? http://www.allinterview.com/showanswers/21562.html It is an instrument used to determine the Sun?s altitude at a given place. 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 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 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 Where is Vikram Sarabai Space Research Centre? http://www.allinterview.com/showanswers/29465.html a) bangalore b) Hyderabad c) Mumbai d) kerala 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 Is exothermic reaction useful in Lasing process? give reasion of ur http://www.allinterview.com/showanswers/36508.html Yes. The exothermic reaction is useful in lasing process. As a laser is emitted by the process of stimulated emmision . so to stimulate the electrons we nedd some external stimulating energy . the heat given up by the exothermic reaction can Explain the Velocity and Acceleration ? http://www.allinterview.com/showanswers/21565.html Rest and motion:-A body is said to be at rest when it does not change its position with respect to its surrounding objects or when it dies not change its position with time The body is said to be in motion when it changes its position with resp What is the normal pulse beat of a human body? http://www.allinterview.com/showanswers/21135.html 78 beats per minute. 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. 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 Why is lighting conductor used ? http://www.allinterview.com/showanswers/21094.html Because it provide an easy passage to the charge from the clouds to the earth and this protects the building grin the destructive effect if the lighting. What is the difference between Centigrade thermometer and a Reaumer t http://www.allinterview.com/showanswers/21144.html The water freezes at Oo C and boils at 100 o C in the Centigrade thermometer while it freezes at Oo R and boils at 80o R in the Reaumer thermometer. At what temperature does the filament of electric bulb glows ? http://www.allinterview.com/showanswers/21126.html Between 2000-2500 o C
