<span>If an object is accelerating then the forces applied on them are unbalanced, balance forces will cause the object to remain stationary or move at a constant velocity.</span>
I’m pretty sure the answer is A but if you already ruled that out try B
Answer:
The best answer choice is C. either from food or sunlight
Explanation:
Humans and Animals need to eat food to get energy
Plants use sunlight to create their own food.
E=hv is an equation important when dealing with light. E refers to the energy of a photon; h is Planck's constant and v is the wavelength. According to this equation, light particles called photons travels in packets of energy. This is important in pv cells because this is the technology used to harness solar energy which is converted to electricity. The amount of energy should be estimated to know the appropriate material of construction of the pv cell to achieve optimum conditions. In this way, the pv cell could maximize the sun's energy.
