Please help me give a summary for trees lessons as I (cody) have a quiz Tommorow Sientific method

Conduction, convection, and radiation

Energy transformations

Law of conversion of energy

Conduction is heat transfer through stationary matter by physical contact. (The matter is stationary on a macroscopic scale—we know that thermal motion of the atoms and molecules occurs at any temperature above absolute zero.) Heat transferred from the burner of a stove through the bottom of a pan to food in the pan is transferred by conduction.

Convection is the heat transfer by the macroscopic movement of a fluid. This type of transfer takes place in a forced-air furnace and in weather systems, for example.

Heat transfer by radiation occurs when microwaves, infrared radiation, visible light, or another form of electromagnetic radiation is emitted or absorbed. An obvious example is the warming of Earth by the Sun. A less obvious example is thermal radiation from the human body.     I hope this helps you

Explanation:

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
