A 1200 kg car is being towed to the shop. The tow truck applies 3200 N of force in order to keep the car moving at a constant velocity. (Friction is present.) What is the horizontal Fnet and vertical Fnet? Determine the coefficient of kinetic friction between the car's tires and the road.

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.

Anybody wanna ? (picture included? )

What can change the speed of sound as it travels through the ocean? a. salinity only b. density and salinity c. salinity and distance from land d. density and distance from land
