Which statement describes a surface wave?
a surface wave is a type of electromagnetic wave.
a surface wave is a wave that travels through space.
a surface wave is a wave that moves along the interface of two different materials, like air and water.

The statement which best describes a surface wave is: C. A surface wave is a wave that moves along the interface of two different materials, like air and water.

A wave can be defined as a disturbance in a medium that progressively transports energy from its source to another location, without the transportation of matter.

In Science (Physics), there are two main (2) types of wave and these are:

A surface wave can be defined as a mechanical wave that moves or propagates between the interface of two different materials such as water and air.

This ultimately implies that, a surface wave is a wave that wave that moves or propagates along the interface of two differing media.

For example, gravity waves that moves or propagates along the surface of water is a surface wave.

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
