Electromagnetic waves ARE radiation.

A wave always carries energy.

Hunter-Best [27]3 years ago
6 0

Answer:

Thermal or Heat energy

Explanation:

There are three ways through which heat transfer, it include conduction, convection and radiation, so radiation is the type of heat transfer.

Electromagnetic waves are those waves which travel with the speed of light. These are generated as the result of vibration between magnetic and electric field and these fields transfer heat or thermal energy through a medium or across vacuum by the process of electromagnetic radiation.

Give proof that mass is constant and weight keeps changing.​
shutvik [7]

The mass of an object stays the same wherever it is, but its weight can change. This happens if the object goes where the gravitational field strength is different from the gravitational field strength on Earth, such as into space or another planet.

★ Principal focus - A number of rays parallel to the principal axis after reflection from a concave mirror meet at a point on the principal axis or appear to come from a point after reflection from a convex mirror on the principal axis. This is called principal focus.

Which of these properties of an object best quantifies its inertia: velocity, acceleration, volume, mass, or temperature?
LuckyWell [14K]

Answer:

Mass

Explanation:

Inertia is essentially an object's tendency to stay in motion or at rest unless it is forced to do otherwise (pun intended). It only makes sense to me that mass would best quantify an object's inertia, because an object with more mass would be harder to move and/or stop from moving.
