Answer:
No matter, what there is always the same amount of energy in the universe!
Explanation:
That is essentially what the Law of Conservation of Energy states, however, this passage. Now I don't really have an in-depth view of what your requirements are, however, the idea is that energy cannot be destroyed or created; it can only be transformed. You have most likely learned about energy transformations: potential to kinetic (being a broad category). If potential energy goes down (for an object), kinetic energy for the object goes up. The Ramsey Box is essentially stating that the less you train, the more you will suck. The total mechanical energy stays the same, and goes up or down together. The less hard work, the more failure. The more hard work, the less failure. Comment if you want more info. I'm in 8th grade too btw:)
Momentum is mass times velocity
360000 * 1.5 =540,000kg m/s
<em>IF</em> this is happening on <u>Earth</u>, then the acceleration of gravity wherever the captain and the roof are is about 9.8 m/s² downward.
<em>IF</em> his shield is not affected by air resistance, and it's free to behave under the influence of gravity alone, then its acceleration is <em>9.8 m/s² downward</em>, from the moment it leaves his hand until the moment it hits a building, a tree, a car, a bus, an evildoer, or the ground.
Whatever speed it has when it leaves his hand, in whatever direction, makes no difference.
Answer:1.27
Explanation:
Given
incident angle 
refracted angle 
Suppose 
is the refractive index of material then using Snell's law we can write
where 
=refractive index of air
