Potential energy is energy that an object possesses due to its position or condition. Examples of potential energy include a stretched rubber band (d.), a car parked at the top of a hill (A.), and rushing water used to turn a turbine (b.).

Sound waves travel fastest through steel due to its high density and stiffness, allowing sound waves to propagate quickly.

Red light is the least bent in a rainbow arc because it has the longest wavelength, causing it to bend the least when passing through a prism.

One statement that is not true about heat and temperature is: B. Temperature is energy in transit while tempervi
