Page 93 - Show that the moment of inertia of a body about any axis is equal to the moment of inertia about a parallel axis through...
Page 99 - Elasticity is the name given to "that property by virtue of which a body requires force to change its bulk or shape, and requires a continued application of the force to maintain the change, and springs back when the force is removed ; and if left without the force, does not remain at rest except in its previous bulk and shape.
Page 92 - V is given either by the product of the charge and the potential difference or by one-half the product of the mass of the particle and the square of the final velocity. Solving (6-9) for the velocity, l2eV v = ^ — - meters/sec (6-10) \ in The energy acquired by an electron (e = 1.6 X 10~19 coulomb) in "falling" through a potential difference of 1 volt is 1.6 X 10~19 joule.
Page 70 - Or in different words, the specific gravity of a body is the ratio of its mass to the mass of an equal volume of a standard substance. Specific gravity is thus a numerical ratio, or an abstract number which is independent of the units employed.
Page 70 - The specific gravity or relative density of a substance is the ratio of its density to the density of some standard substance.
Page 68 - P = pressure for absolute temperature t and p' the pressure for t temperature also absolute, then nt P ' or if v be the volume at absolute temperature t and v' at t', then v _t v'~t'' Boyle's law states that the product of the pressure and the volume of a perfect gas remains constant if the temperature of the gas is unchanged, denoting pressure by p and volume by v. Boyle's law is pv = constant. If heat is supplied to a perfect heat engine at absolute temperature T and the absolute temperature of...
Page 8 - This line should be drawn so that there are about as many points on one side of it as on the other side.
Page 93 - The moment of inertia of a body about a given axis is 1.2 kg m2.
Page 91 - The general value of the moment of inertia of a particle of mass m about an axis distant r can be easily obtained as follows : In the same way that it is known from experiment that the T • if : , i J- Fort'?
