Página 165 - 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.
Página 65 - Every body continues in its state of rest, or of uniform motion in a straight line, unless it is compelled to change that state by forces impressed upon it.
Página 5 - ... 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...
Página 96 - 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.
Página 302 - ... 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.
Página 64 - A rifle-bullet is shot vertically downwards from a balloon at the rate of 400 ft. per second. How many feet will it pass through in two seconds, and what will be its velocity at the end of that time, neglecting the resistance of the air, and estimating the acceleration due to gravity at 32 P [864 ; 464 ft.
Página 524 - The coils are set parallel to the needle (ie, in the magnetic meridian). The current is then sent through the coils, deflecting the needle. The coil is then turned until it overtakes the needle, which once more lies parallel to the coil.
Página 205 - E ; each boy, after the transmission ot 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 close to a drum-head, he would have shaken the drum.
Página 480 - 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.
Página 168 - 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.
