Object Located Between the Focal Point and the Mirror
Ray diagrams are meaningful tools for denoting the location of an image as generates through a concave mirror. To denote the location of an image by using a ray diagram, at least two sets of incident and reflected rays should be constructed for strategic positions on the object. The image of an object is the location while light rays from in which object intersect upon reflecting from a mirror. Through constructing at least two sets of incident and reflected rays and this image location can simply be found.
how to get the formula ?.
A boy throws a ball of mass 20 kg vertically upwards.It raises to a maximum height of 100 m.At what height will the kinetic energy be reduced to 70%?
Q. Give the differences between hard X-rays and soft X-rays.
Thevenin's Theorem can be stated as follows: Any two terminal network having a number of e.m.f. sources and resistances can be changed by equivalent simple series circuit of singl
Ans) In the first one..... F=ma...the only force which acts is F...which causes an acc. of ''a'' to the body of mass m... and as the force=>F=ma but on the second... let .
Coulomb: Coulomb is the fundamental unit of charge. It is explained as the charge required to obtain 9?109 newton of force among two equal charges separated at a distance of one m

Heat may be transmitted from one body to the other by any of three possible ways: conduction, radiation and convection. In the conduction, convection phenomena, a medium is essent
Refractive index: The most important optical measurement for any transparent material is its refractive index (n). The refractive index is the ratio of the speed of light (c)
