ANSWERS TO QUESTIONS
Q1.1 Atomic clocks are based on electromagnetic waves which atoms emit.
Also, pulsars are highly regular astronomical clocks.
Q1.2 Density varies with temperature and pressure. It would be necessary
to measure both mass and volume very accurately in order to use the
density of water as a standard.
Q1.3 (a) 0.3 millimeters (b) 50 microseconds (c) 7.2 kilograms
Q1.4 (b) and (d). You cannot add or subtract quantities of different dimension.
Q1.5 A dimensionally correct equation need not be true. Example: 1 chimpanzee = 2 chimpanzee is
dimensionally correct. If an equation is not dimensionally correct, it cannot be correct.
Q1.6 On February 7, 2005, I am 59 years and 39 days old.
