Question 13: Will a clock using a pendulum supported on a long thin brass rod that is accurate at 20°C run fast or slow on a hot day (30°C)? Explain.
Question 10: The units for the coefficient of linear expansion \({\bf{\alpha }}\) are \({\left( {{\bf{C^\circ }}} \right)^{{\bf{ - 1}}}}\)and there is no mention of a length unit such as meters. Would the expansion coefficient change if we used feet or millimeters instead of meters? Explain.
