331. lappuse - When a ray of light passes from one medium to another, it is refracted so that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the velocities in the two media.
33. lappuse - Every body continues in its state of rest or of uniform motion in a straight line, except in so far as it may be compelled by impressed forces to change that state.
222. lappuse - Resistance Inversely Proportional to Cross-Section. The resistance of a conductor is inversely proportional to its cross-sectional area. Hence the greater the cross-section of a wire the less is its resistance. Therefore, if two wires have the same length, but one has a cross-section three times that of the other, the resistance' of the former is one-third that of the latter.
50. lappuse - Newton generalized the law of attraction into a statement that every particle of matter in the universe attracts every other particle with a force which varies directly as the product of their masses and inversely as the square of the distance between them; and he thence deduced the law of attraction for spherical shells of constant density.
33. lappuse - Change of motion is proportional to the impressed force and takes place in the direction of the straight line in which the force acts.
228. lappuse - The strength of the current is proportional to the tangent of the angle of deflection.
112. lappuse - The loss of weight of a body immersed in a fluid is equal to the weight of the displaced fluid, or a body immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by it.
315. lappuse - AC (Fig. 124), the greater part of it is reflected in a definite direction. The angle that the incident ray makes with the normal PB to the reflecting surface at the point of incidence is called the angle of incidence, as IBP ; and the angle between the reflected ray and this normal is the angle of reflection, as RBP.
329. lappuse - The incident ray, the reflected ray, and the normal to the surface at the point of incidence, all lie in the same plane. When a ray of light is refracted, n sin <t> = n...
49. lappuse - All that we know about matter relates to the series of phenomena in which energy is transferred from one portion of matter to another, till in some part of the series our bodies are affected, and we become conscious of a sensation.
