<h2>Answer:Radiation-3,Conduction-1,Convection-2</h2>

Explanation:

Radiation is the transfer of heat through electromagnetic waves.

These waves do not require any medium.This is the way we get heat from sun.Radiation is the quickest mode to transfer of heat.

Conduction is the transfer of heat through collisions of atomic particles.

This phenomenon largely occurs in solids like metals.The neighbour atoms sets the atoms into random motion thereby raising the temperature.

Convection is the transfer of heat through actual movement of medium particle.

This phenomenon occurs in gases an liquids.The medium particles actually traverse through the space transferring the heat.

An object that has kinetic energy must what ?
11Alexandr11 [23.1K]

An object that has kinetic energy must be <em>moving</em>.

The formula for an object's kinetic energy is

KE = (1/2) · (the object's mass) · <u><em>(the object's speed)²</em></u>

As you can see from the formula, if the object has no speed, then its kinetic energy is zero.  That's why kinetic energy is usually called the "energy of motion", and if an object HAS kinetic energy, then that tells you right away that it must be moving.
