Answer:
a round shape. It has its own gravity to pull itself into a round shape
Answer:
C Don't worry if you thought it was D. I almost answered that.
Explanation:
Remark
You can get this just by learning the vocabulary.
Efficiency = Work Out / Work In * 100%
Work in = 30J That's you swinging the hammer.
Work out = 10 J That's how much of the hammer's work gets to the nail.
Efficiency = (10/30)*100
Efficiency = 1/3 * 100
Efficiency = 33%
Answer:
do explain what u need help with?
Because they are larger planets the gravitational pull is heavier and they attract more celestial bodies
One
All objects, every one, as long as the object is not at absolute zero (not very many objects are -- like no common object) emit electromagnetic radiation because they possess thermal (heat) energy.
The answer, surprisingly, is A.
Two
This is just an example of Snells law. The angles are with the normal.
Index of Refraction = sin(input angle) / sin(outgoing angle)
Index of Refraction = sin(angle incidence)/sin(angle of refraction)
Index of Refraction = Sin (36)/Sin(27.5)
Index = 1.28 (rounded)
