Stokes' law describes sedimentation of particles in liquids and can be used to measure viscosity. particles in liquids achieve terminal velocity quickly. one can measure the time it takes for a particle to fall a certain distance and then use stokes' law to calculate the viscosity of the liquid. suppose a steel ball bearing (density 7.8 ✕ 103 kg/m3, diameter 2.4 mm) is dropped in a container of motor oil. it takes 10 s to fall a distance of 0.75 m. calculate the viscosity (in kg/(m·s)) of the oil.

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.
