Hello, how's your day going?
if humanity came together and made a base on the moon, it would be revolutionary. The point of a base on the moon would have multiple purposes. for example, some think that the moon contains valuable metals such as iron and titanium. a base would serve as a place for workers harvesting metals to rest. Obviously or not most of the iron harvesting would be done automatically by robots and such.
If such a base were constructed on the moon, it would be the begining of people living on other worlds and would be a great start for a base on Mars.
Hope it helped

Answer: the potental with twice larger radius 0.5* Vo ( being Vo =100V)
Explanation: In order to solve this proble, we know that teh potential due to charged sphere relative V=0 at infinity, we have
Vo=k*Q/R where R is the sphere radius
if we enlarge the radius to 2R the
V= k*Q/2*R = Vo/2
Answer:
![\phi=1.55 [eV]](https://tex.z-dn.net/?f=%5Cphi%3D1.55%20%5BeV%5D)
Explanation:
We can use the work function equation for a photoelectric experiment:
- h is the plank constant
- c is the speed of light
- λ is the wave length
- K is the kinetic energy (or K=eΔV)
So we will have:
![\phi=3.64*10^{-19}[J]-0.728 [eV]](https://tex.z-dn.net/?f=%5Cphi%3D3.64%2A10%5E%7B-19%7D%5BJ%5D-0.728%20%5BeV%5D)
![\phi=(3.64*10^{-19}[J]*\frac{1eV}{1.6*10^{-19}[J]})-0.728 [eV]](https://tex.z-dn.net/?f=%5Cphi%3D%283.64%2A10%5E%7B-19%7D%5BJ%5D%2A%5Cfrac%7B1eV%7D%7B1.6%2A10%5E%7B-19%7D%5BJ%5D%7D%29-0.728%20%5BeV%5D)
![\phi=2.28 [eV] - 0.728 [eV]](https://tex.z-dn.net/?f=%5Cphi%3D2.28%20%5BeV%5D%20-%200.728%20%5BeV%5D)
