Page 34 - Every body continues in its state of rest or of uniform motion in a straight line, except in so far as it may be compelled by impressed forces to change that state.
Page 363 - As a unit of resistance, the international ohm, which is based upon the ohm equal to 10" units of resistance of the CGS system of electromagnetic units, and is represented by the resistance offered to an unvarying electric current by a column of mercury at the temperature of melting ice, 14.4521 grams in mass, of a constant cross-sectional area and of the length of 106.3 centimetres.
Page 109 - The pressure of a liquid on any surface immersed in it is equal to the weight of a column of the liquid whose base is the...
Page 369 - Under these conditions the strength of the current is proportional to the tangent of the angle of deflection.
Page 322 - The force of attraction or repulsion between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
Page 113 - A solid immersed in a liquid is buoyed up by a force equal to the weight of the liquid displaced.
Page 48 - Every particle of matter in the universe attracts every other particle, with a force whose direction is that of the line joining the two, and whose magnitude is directly as the product of their masses, and inversely as the square of their distance from each other.
Page 360 - Grasp the coil with the right hand so that the fingers point in the direction of the current in the coil, FIG.
