Ball 4 because the higher the elevation is the greater the potential energy it has
Answer:
The angle of launch of the rubber band affects the initial velocity. The more the rubber band is stretched the more force it applies to return to equilibrium and the more kinetic energy that results in.
No, there are not any carbon atoms inside this compound.
The compound is
. This means there are 3 "Ca" atoms and 2 "N" atoms.
- Ca is calcium
- N is nitrogen
Thus, none of the elements in this compound are carbon, meaning there are no carbon atoms. Let me know if you need any clarifications, thanks!

Answer:
k = 104.46 N/m
Explanation:
Here we can use energy conservation
so we will have
initial gravitational potential energy = final total spring potential energy
as we know that she falls a total distance of 31 m
while the unstretched length of the string is 12 m
so the extension in the string is given as
![x = L - L_o](https://tex.z-dn.net/?f=x%20%3D%20L%20-%20L_o)
![x = 31 - 12 = 19 m](https://tex.z-dn.net/?f=x%20%3D%2031%20-%2012%20%3D%2019%20m)
so we have
![mgH = \frac{1}{2}kx^2](https://tex.z-dn.net/?f=mgH%20%3D%20%5Cfrac%7B1%7D%7B2%7Dkx%5E2)
![62(9.81)(31) = \frac{1}{2}k (19^2)](https://tex.z-dn.net/?f=62%289.81%29%2831%29%20%3D%20%5Cfrac%7B1%7D%7B2%7Dk%20%2819%5E2%29)
![k = 104.46 N/m](https://tex.z-dn.net/?f=k%20%3D%20104.46%20N%2Fm)
