Answer:
Explanation:
We just have to calculate what angular displacement a ball with an average angular velocity of 290 rev/min experiments in 0.64s. By definition, angular velocity 
is the angular displacement 
divided by the time elapsed:
Since 
and 
, we can covert:
Where the terms between parenthesis are equal to 1, so they just change the units. Then for our values we have:
8 seconds, because if you use the formula distance divided by speed it would give you the time. So, if you divide 112 by 14 your answer would be 8. Hope this helped. Mark as brainliest if you can pls?
The cell theory states that:
1) All living organisms are composed of one or more cells.
2) The cell is the basic unit of structure and organization in organisms.
3) Cells arise from pre-existing cells.
Your statement is not present, so the answer would be no.

Answer:
To summarize, potential energy is the energy that is stored in an object due to its position relative to some zero position.
Explanation:
An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.
Answer:
ΔL=0.14m
Explanation:
The period of oscillations of simple pendulum is
Here L is length of pendulum and g is acceleration due to gravity
So the length of pendulum is:
So increase in length is:
ΔL=L₂-L₁
![=\frac{T_{2}^{2}g }{4 \pi^{2} }-\frac{T_{1}^{2}g }{4 \pi^{2} }\\=\frac{g}{4 \pi^{2} }[T_2^{2} -T_1^{2} ]\\ =\frac{9.8}{4 \pi^{2}}[(1.15+0.22)^{2}-(1.15)^{2} ] \\=0.14m](https://tex.z-dn.net/?f=%3D%5Cfrac%7BT_%7B2%7D%5E%7B2%7Dg%20%7D%7B4%20%5Cpi%5E%7B2%7D%20%7D-%5Cfrac%7BT_%7B1%7D%5E%7B2%7Dg%20%7D%7B4%20%5Cpi%5E%7B2%7D%20%7D%5C%5C%3D%5Cfrac%7Bg%7D%7B4%20%5Cpi%5E%7B2%7D%20%7D%5BT_2%5E%7B2%7D%20-T_1%5E%7B2%7D%20%5D%5C%5C%20%3D%5Cfrac%7B9.8%7D%7B4%20%5Cpi%5E%7B2%7D%7D%5B%281.15%2B0.22%29%5E%7B2%7D-%281.15%29%5E%7B2%7D%20%20%5D%20%5C%5C%3D0.14m)
