Σελίδα 32 - Change of motion is proportional to the impressed force and takes place in the direction of the straight line in which the force acts.
Σελίδα 91 - 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.
Σελίδα 147 - The Specific Gravity of a substance is the ratio of its weight to that of an equal volume of water.
Σελίδα 143 - ... of the compressed air; in other respects the working of the pump is similar to that of the lifting pump. The advantage of the air chamber is that it produces a steady stream from the nozzle instead of an intermittent one. 74. The Siphon. The siphon (Fig. 44) is an instrument for transferring liquids from one vessel to another at a lower level. It consists of a bent tube, with arms of unequal length filled with liquid and inverted with the shorter arm in the vessel from which the liquid is to...
Σελίδα 228 - It will be seen from the above that the number of beats per second is equal to the difference in the vibration numbers of the two forks.
Σελίδα 136 - ... Pascal's Vases. pressure exerted on the disc detaches it from the ring. An indicator marks the level of the liquid when this takes place. Let the experiment be repeated with the two other vases, and the disc will be detached when the water has reached the same height; showing plainly that the pressure on the bottom of a vessel is independent of the shape of the vessel. But...
Σελίδα 260 - The quotient found by dividing the sine of the angle of incidence by the sine of the angle of refraction, is called the index of refraction. As different bodies have different refractive powers, they will present different indices, but in the same substance it is always constant. Thus, the refractive index of water is 1.335, of flint glass, 1.55, of the diamond, 2.487.
Σελίδα 138 - ... barometer. The barometer. The principle of the barometer is as follows: A tube more than 30 inches long, closed at one end, is filled with mercury. The open end of the tube is then placed in a dish of mercury (Fig.
Σελίδα 173 - The ratio of the quantity of heat required to raise the temperature of a given mass of any substance 1° to the quantity of heat required to raise the temperature of an equal mass of water 1° is called the specific heat of the substance.
Σελίδα 199 - The frequency is the number of waves that pass a given point in one second.
