On a hot summer day, heat waves can be seen rising from the asphalt. what type of heat transfer do the heat waves demonstrate?

There are three types of heat transfer namely convection, conduction and radiation. For this situation, the heat waves seen from the asphalt is an example of heat transfer called radiation. Radiation is the transfer of heat energy by electromagnetic radiation. The heat from the sun absorbed by the asphalt is called the radiant energy which causes it to emit heat waves.

That depends on what kind of environ meant it is in  in space it has the same force that was applied when the velocity was gained
