3) If engineers can use potential energy to calculate how fast an object moves
when it falls, in what kind of situations or places would an engineer use this
information?

increased stability in the completion of fluorine's outer shell.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
