A floating photovoltaic panel, measuring 10m x 3m is anchored in an estuary. Each side can be treated like a flat plate. The wind passes at 30 mph over the top and approaches squarely at the 3m-side. The water flows in the opposite direction at 1 m/s. What is the net frictional force on the floating PV

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
