Answer: Atmosphere and geosphere.
Geo-sphere is the solid part of the earth. Hydrosphere is the water part. The living things on the earth make up the biosphere. The gases, water vapors etc make up the atmosphere. When a volcanic eruption adds carbon dioxide to the air, the carbon-dioxide is being added from geosphere to the atmosphere. Hence, there is interaction between atmosphere and geosphere.

Explanation:
<u>Uniform Circular Motion
</u>
The cork is performing a circular motion which we assume to be uniform (constant angular speed or angular acceleration zero)
The centripetal force applied to it is given by
![F_c=m\ a_c](https://tex.z-dn.net/?f=F_c%3Dm%5C%20a_c)
where m is the mass and
is the centripetal acceleration. This acceleration appears since the tangent speed is constantly changing direction. If w is the angular speed and r is the radius of rotation
![a_c=w^2r](https://tex.z-dn.net/?f=a_c%3Dw%5E2r)
The speed of the cork can be found with the formula
![v=wr](https://tex.z-dn.net/?f=v%3Dwr)
We can compute w since we know the rotation period <em>T=1.25 sec
</em>
![w=\frac{2\pi}{T}=\frac{2\pi}{1.25}=5.027\ rad/sec](https://tex.z-dn.net/?f=w%3D%5Cfrac%7B2%5Cpi%7D%7BT%7D%3D%5Cfrac%7B2%5Cpi%7D%7B1.25%7D%3D5.027%5C%20rad%2Fsec)
Now, since r=0.30 m, let's compute v
![v=wr=(5.027)(0.3)=1.5081\ m/s](https://tex.z-dn.net/?f=v%3Dwr%3D%285.027%29%280.3%29%3D1.5081%5C%20m%2Fs)
![a_c=5.027^2(0.3)=7.58\ m/sec^2](https://tex.z-dn.net/?f=a_c%3D5.027%5E2%280.3%29%3D7.58%5C%20m%2Fsec%5E2)
And finally
![F_c=(0.025)\ (7.58)=0,189\ Nw](https://tex.z-dn.net/?f=F_c%3D%280.025%29%5C%20%287.58%29%3D0%2C189%5C%20Nw)
