Page 83 - It has been found by experiment that the weight of a body varies inversely as the square of its distance from the center of the earth. If a...
Page 219 - The logarithm of a number is the exponent of the power to which it is necessary to raise a fixed number, in order to produce the first number.
Page 29 - The hypotenuse of a right triangle is the side opposite the right angle. The sides including the right angle are sometimes called the arms of the right triangle.
Page 298 - The characteristic of a number less than 1 is found by subtracting from 9 the number of ciphers between the decimal point and the first significant digit, and writing — 10 after the result.
Page 81 - The velocity of a falling body varies as the time during which it has fallen from rest. If the velocity of a falling body...
Page 87 - It has been found by experiment that the distance a body falls from rest varies as the square of the time.
Page 45 - P = mean effective pressure in pounds per square inch; L = length of stroke in feet; A =area of piston in square inches; N = number of strokes per minute = revolutions per minute x 2.
Page 83 - The Volume of a Gas. The volume of a gas varies inversely as the height of the mercury in the barometer.
Page 242 - The logarithm of a fraction is equal to the difference obtained by subtracting the logarithm of the denominator from the logarithm of the numerator : log (os/6) = log a — log b. For, if 10' = a and 10£ •= b, then IQI-L — a _}.
Page 100 - Glasgow had already discovered in 1830 his "law of gaseous diffusion" ( the relative rates of diffusion of gases are inversely proportional to the square roots of the densities) when he began his work on the phosphoric acids.
