Page 50 - 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.
Page 129 - When a number of resistances are connected in series, the total resistance is equal to the sum of the separate resistances.
Page 3 - To every action there is always an equal and contrary reaction ; or the mutual actions of any two bodies are always equal and oppositely directed.
Page 72 - Dalton's law. — The pressure of a mixture of several gases in a given space is equal to the sum of the partial pressures which each gas would exert if it were confined alone in the space.
Page 32 - Pressure exerted anywhere upon a mass of liquid is transmitted undiminished in all directions, and acts with the same force on all equal surfaces, and in a direction at right angles to those surfaces.
Page 3 - Change of motion is proportional to the impressed force and takes place in the direction of the straight line in which the force acts.
Page 69 - Heat can never pass from a colder to a warmer body without some other change, connected therewith, occurring at the same time.
Page 69 - If the total actual heat of a homogeneous and uniformly hot substance be conceived to be divided into any number of equal parts, the effects of those parts in causing work to be performed are equal.
