Answer:
37500 J
Explanation:
Law of conservation of energy: Its states that energy can neither be created nor destroyed but it can be transformed from one form to another.
Applying the law of conservation of energy.
The change in kinetic energy for the truck = Net work done by the truck skids
ΔK.E = F×d.................... Equation 1
Where ΔK.E = Change in kinetic energy, F = Force, d = distant.
Given: F = 1500 N, d = 25 m
Substitute these values into equation 1
ΔK.E = 1500×25
ΔK.E = 37500 J
Answer:
No, false.
Explanation:
You may use it to power a light bulb if you desired. The reason it isn't is because it's inconsistent not predictable.
On a clear cloudless day, the sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we visually perceive red and orange colors because the blue light has been scattered out and away from the line of optical discernment.
Hope this helps! :)
