Page 146 - Archimedes stated that a body immersed in a fluid is buoyed up by a force equal to the weight of the displaced fluid.
Page 145 - A body immersed in a liquid is buoyed up by a force equal to the weight of the liquid displaced by it.
Page 13 - IMPENETRABILITY is that property by virtue of which no two bodies can occupy the same place at the same time. This property is self-evident, although phenomena are observed which would seem to conflict with it. Thus, when a pint of alcohol is mixed with a pint of water, the volume of the resulting mixture is less than a quart. This...
Page 184 - ... air and the smallness of the tube. The bulb is therefore heated, when the air within expands, and a portion escapes in bubbles through the mercury. On cooling, the pressure of the external atmosphere forces a quantity of mercury through the tube into the bulb. By repeating this operation a few times, the bulb and a portion of the tube are filled with mercury. The whole is then heated till the mercury boils, thus filling the tube, when the funnel is melted off and the tube hermetically sealed...
Page 36 - 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.
Page 160 - Sounds are propagated better in calm than in stormy weather, also with more intensity in the direction of the wind than in the contrary direction. A modification of the law, that the intensity of sound varies inversely as the square of the distance, takes place when sound is caused to travel through long smooth tubes. The sound moves like the rings produced in a pool of water by a falling stone: they...
Page 271 - The following definitions apply equally to concave and convex mirrors : The middle point of the mirror is called its vertex. The centre of the sphere, of which the mirror forms a part, is called the optical centre.
Page 437 - Two wires, one connected with the positive, and the other with the negative pole of a...
Page 280 - ... 1. The planes of incidence and refraction coincide, both being normal to the surface separating the media, at the point of incidence. 2. The sine of the angle of incidence is equal to the sine of the angle of refraction multiplied by a constant quantity.
Page 215 - The heat which is expended in changing a body from the solid to the liquid state, or from the liquid to the gaseous state, is called latent heat.
