Either theory or evidence
Who knows. Noone does. That question is way to hard I'm only in 6th grade
To find instantaneous velocity given a position vs. time graph is find the derivative at that given point. In other words, find the slope at that point.
So at t = 1s, the velocity is 5/2 m/s.
Hope this helps!
The one with the majority of its mass furthest away from its center will reach the bottom last. The thin walled cylinder has all of its mass at the edge of itself, meaning its mass is the furthest from its center. If we take a look at the solid cylinder, it has some mass at its edge, but it also has a lot of mass very close to its center so it will roll faster than the thin walled cylinder. And the thin walled cylinder will be slower than the normal hollow cylinder because even though the hole cylinder doesn't have any mass at its center it does have some mass closer to its center than the thin walled cylinder.
So the last one to reach the bottom is the thin walled cylinder.
Answer:
1st one is dependent
2nd is independent
3rd is dependent
4th is dependent
Explanation:
independent clauses are sentences that can be on their own and make sense dependent clauses don't make sense on their own
