This shows that the length of a pendulum that makes one full swing in 2.2 seconds is 392.71 feet.
Given the formula for calculating the length of the pendulum expressed as:
where:
L is the length of the pendulum
T is the period of the pendulum
Given the following parameters:
Period T = 2.2 seconds
Substitute the given parameters into the formula will give;
So, this shows that the length of a pendulum that makes one full swing in 2.2 seconds is 392.71 feet.

The runner's displacement and average velocity are both zero. (I hope this answer is on the list of choices that you neglected to share.)
Answer:
1. Simply τ = m x g x r = 54kg x 9.8m/s² x 0.050m = 26 N·m
2. The bucket creates a torque
τ = 75kg x 9.8m/s² x 0.075m = 55 N·m,
so we must create the same torque with the handle.
55 N·m = F x 0.25m
F = 220 N

Hope this is helpful
The answer would be a bicycle as it uses both wheels and an axel
Answer:
It would be (a)
Explanation:
A theory is something that can be proved through rigorous and repeated experimentation, while choice (b) sounds tempting i believe it fails at the fact that it says that a theory is an "agreement", sure an agreement could be reached by while trained scientists but that does not necessarily mean that what the scientists agree upon is rigorously tested and repeatable, and so therefore cannot be assumed
That is what I think
Hope this helps :)
