Exam (elaborations) PHYS 195 graded A+ 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 People have different size hands. Defining the unit precisely would be cumbersome. Q1.4 (a) 0.3 millimeters (b) 50 microseconds (c) 7.2 kilograms Q1.5 (...

Using a calculator to multiply the length by the width gives a raw answer of 6783 m2, but this answer must be rounded to contain the same number of signifi cant fi gures as the least accurate factor in the product. The least accurate factor is the length, which contains either 2 or 3 signifi cant fi gures, depending on whether the trailing zero is signifi cant or is being used only to locate the decimal point. Assuming the length contains 3 signifi cant fi gures, answer (c) correctly expres...
