If a ramp were coated with a smoother surface, the ramp’s efficiency would increase because friction would decrease decrease because friction would increase increase because friction would increase decrease because friction would decrease

Increase because friction would decrease.

Coating the ramp with a smoother surface will decrease the friction. A decrease in friction will help to slide any object up the ramp easily. Thus, a lesser energy will be spent as compare to earlier. Hence, the ramp's efficiency will increase.

hail is a solid form of precipitation composed of large, layered ice particles called pellets that often have spherical shapes. this phenomenon occurs during thunderstorms in the could type known as cumulus

hope this you out ^w^

specific latent heat of fusion, lf, of a substance is defined as the amount of heat required to change a unit mass of the substance from solid to liquid state, without any change in the temperature.
