Answer:
nuclear energy.............
The sun's energy begins in the nuclear form of energy. Nuclear energy is the origin of the sun's energy.
Nuclear energy originates from the sun's energy. Nuclear fusion processes happen at the sun's core, transforming protons from hydrogen into helium and releasing a tremendous amount of energy in the process. Nuclear fusion is the term for this action.
Helium nuclei are created from the collision and fusion of hydrogen nuclei in the sun's core, which experiences extremely high temperatures and pressures. An enormous quantity of energy is released during the nuclear fusion process in the form of electromagnetic radiation, especially visible light photons and other types of electromagnetic radiation.
The intense heat and brightness of the sun are maintained by the energy generated by nuclear fusion in its core, giving it a potent source of light and heat that sustains life on Earth and powers a variety of atmospheric and climatic processes.
Hence, the sun's energy begins in the nuclear form of energy. Nuclear energy originates the sun's energy.

Answer:
When you know both the speed and direction of an object's motion, you know the velocity of the object.
When you know both the speed and direction of an object’s motion, you know the magnitude of the speed and direction in which it is moving.
What is Speed ?Speed is a rate of change of distance with respect to time. i.e. v =dx÷dt.
Speed can also be defined as distance over time
i.e. speed= distance ÷ time
it is denoted by v and its SI unit is m/s. it is a scalar quantity. i.e. it has only magnitude not direction. ( velocity is a vector quantity, it has both magnitude and direction. when we define velocity, we should know about its direction)
Speed shows how much distance can be traveled in unit time.
As speed is scalar quantity it has nothing to do with the direction. but when magnitude of speed is given and the direction as well, then we can say that a car or body is moving with this much speed at this direction(east, north, west, south).
