1# The ball flying through the air has two types of energy, kinetic from its velocity and potential from its height off the ground.
It goes from Kinetic when it is at rest to potential on its way to the bottom. There is also friction but very few people care about that.
Answer:
nuclear fusion
<h3>The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.</h3>
Answer:
the answer is the diagram B
Answer:
F3 is the equilibrant force equal in magnitude to the resultant between F1 and F2 but opposite in direction to it.
Explanation:
Given the diagram, the force F3 to make the body remain at rest or in equilibrium is the equilibrant force, this force is equal in magnitude to the resultant Fr between F1 and F2 but opposite in direction to it.
See attachment for diagram of forces.
The resultant force;
Fr =√ (F1)² + (F2)²...(1) [diagram a]
Therefore the length of F3 is Fr
F3 = -Fr
The direction (diagram b) of the resultant force Fr is given by
∆ = acrtan[(F1/F2)]
The direction of F3 is [90 + arctan(F1/F2)]
As seen in the diagram (d), the location of the force is in the fourth quadrant.
