Answer:
a. You should use the thin cooking twine.
Explanation:
The velocity of wave on a rope is:
(1)
with T the tension and μ the linear density of the rope that is defined as , so (1) is:
with M the mass and L the length
Note that if L and T remain constant for bigger M velocity is going to be smaller and vice versa. So, we should chose the lighter rope that is the thin cooking twine to have the fastest wave speed.
If you meant "What does the Earths system include?" here's your answer. The Earths system includes the atmosphere, which has all the planets air in it.
How about a carousel (merry go round).
For any one horse or rider, Speed is constant but direction keeps changing, so velocity does too.
