Can a simple pendulum clock be used in an artificial satellite? Why?
(N/A) No,a simple pendulum clock cannot be used in an artificial satellite. The time period of a simple pendulum is given by $T = 2\pi \sqrt{\frac{l}{g_{eff}}}$. In an artificial satellite,objects experience a state of weightlessness,which means the effective acceleration due to gravity $(g_{eff})$ is $0$. As $g_{eff} \to 0$,the time period $T \to \infty$. This implies that the pendulum will not oscillate,and the clock will stop working.
