Density and pressure — practice question
The coin has the form of a thin cylinder, as illustrated in Fig. 2.1. Fig. 2.2 presents the measurements taken to find the density \(\rho\) of the substance from which the coin is made.
(a)[3]
Calculate the density \(\rho\), in \(\text{kg m}^{-3}\).
(b(i))[3]
Calculate the percentage uncertainty in \(\rho\).
(b(ii))[1]
State the value of \(\rho\) together with its absolute uncertainty.
(main)[1]
Calculate the resultant force acting on the box.
