Page 64 - It is measured by the product of the force by the force arm (the force arm is the perpendicular distance from the axis of rotation to the line of direction in which the force acts).
Page 148 - ... Evidently the same amount of heat lost by the water and calorimeter was gained by the ice and the water from the melted ice. Part of the heat was used in melting the ice; part in warming the water which resulted from melting the ice. It now remains to determine upon a unit of heat. We will adopt for our unit that amount of heat which will raise the temperature of 1 g. of water 1° C. We will call this a calorie. If one calorie will heat 1 g. of water 1° C., will one calorie be given out by 1...
Page 260 - It may also be defined as the sine of the angle of incidence divided by the sine of the angle of refraction, as light passes from air into the substance.
Page 203 - Either part of the divided circuit is considered as a shunt to the other part. Discussion The Wheatstone Bridge is an instrument for measuring an unknown resistance by comparison with a known resistance. The theoretical arrangement of the bridge is shown in Fig. 66. It consists of four resistances, a, b, d, and x, (arranged in the form of a parallelogram); a battery occupying the place of one diagonal, a galvanometer the other. When the resistances are so arranged that no current flows through the...
Page 192 - NOTE. — The unit of electrical resistance is called the ohm and is the resistance of a uniform column of mercury 106.3 cm. long and 1 sq. mm. in area (14.4521 g. in mass) at 0° C. Directions. — a. Connect the apparatus as shown in Fig. 60, setting and using the galvanometer as directed in the Discussion, p. 186. Close the circuit through the galvanometer with 1 ohm resistance in the box and record the deflection of the two ends of the pointer. How much FIG. 60.
