Page 161 - Principle states that a body wholly or partially immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by it.
Page 92 - 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 298 - ... to that required to raise the temperature of the same weight of water one degree from the temperature of maximum density 39.1 is commonly called the specific heat of the substance.
Page 163 - The specific gravity of a substance is the ratio between the weight of any volume of the substance and...
Page 527 - ... round one set of coils of the galvanometer, the other part of the current being made to flow through the known resistances and then round the other set of coils in the opposing direction. When we have succeeded in matching the unknown resistance by one equal to it from amongst the known resistances, the currents in the two branches will be equal, and the needle of the differential galvanometer will show no deflexion.
Page 3 - ... laboratory as it is in the ordinary recitation or lecture room. The great utility of the laboratory note-book is emphatically stated. To the objection that the kind of instruction described requires much time and effort on the part of the teacher, the Conference reply that to give good instruction in the sciences requires of the teacher more work than to give good instruction in mathematics or the languages ; and that the sooner this fact is recognized by those who have the management of schools...
Page 334 - When a small object is at the center of curvature, the image is real, inverted, of the same size as the FIGURE 236.
Page 478 - Six cells, each having an emf of 2 volts and an internal resistance of 0.3 ohms, form a series battery to send a current through a resistance of 50 ohms.
Page 163 - To Find the Density of a Solid Heavier than Water. — The most common way of determining the density of such a body, if it is insoluble in water, is to find its weight in air (w); find its weight when immersed in water («,'); divide the weight in air by the loss of weight in water.
Page 201 - E is now foremost, and A finishes the row behind. I suddenly push A ; A pushes B, and regains his upright position; B pushes c; C pushes D ; D pushes E ; each boy, after the transmission of the push, becoming himself erect. E, having nobody in front, is thrown forward. Had he been standing on the edge of a precipice, he would have fallen over ; had he stood in contact with a window, he would have broken the glass ; had he been...
