When the temperature of a certain solid, rectangular object increases by Delta T, the length of one side of the object increases by 0.010% = 1.0 10^-4 of the original length. The increase in volume of the object due to this temperature increase is A. 0.01% = 1.0 10^-4 of the original volume. B. (0.010)^3 % = 0.0000010% = 1.0 10^-4 of the original volume. C. (1.0 10^-4)^3 = 0.0000000001% = 1.0 10^-12 of the original volume. D. 0.030% =...
