Answer:
Frequency is the number of wavelengths, which is measured in hertz.
Explanation:
I have my ways ;)
Answer:
The ratio is 
Explanation:
Generally the Moment of inertia of a spherical object (shell) is mathematically represented as

Where m is the mass of the spherical object
and r is the radius
Now the the rotational kinetic energy can be mathematically represented as

Where
is the angular velocity which is mathematically represented as

=> ![w^2 = [\frac{v}{r}] ^2](https://tex.z-dn.net/?f=w%5E2%20%20%3D%20%20%20%5B%5Cfrac%7Bv%7D%7Br%7D%5D%20%5E2)
So
![RE = \frac{1}{2}* [\frac{2}{3} *mr^2] * [\frac{v}{r} ]^2](https://tex.z-dn.net/?f=RE%20%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2A%20%20%5B%5Cfrac%7B2%7D%7B3%7D%20%2Amr%5E2%5D%20%2A%20%20%20%5B%5Cfrac%7Bv%7D%7Br%7D%20%5D%5E2)

Generally the transnational kinetic energy of this motion is mathematically represented as

So


Answer:
hey I am in class 6 why did you ask
Idk<span>Around what year can Carbon-14 dating be used up to and why?</span>
Answer:
Sometimes
Explanation:
Sometimes meaning in occasions. If it is a "vampire star" not likely because they also cause they also make novas happen by sucking the gas from another star.
