The mass of the moon is 7.36×1022kg and its distance to the Earth is 3.84×108m.
What is the gravitational force of the moon on the earth?
The moon's force is what percent of the sun's force?
Using Newton's gravitational force equation $F=(Gm_1m_2)/(r^2)$ and assuming that the mass of is $m_1=5.972*10^24kg$ and $m_2$ is the given mass of the moon with $G$ being $6.674*10^-11Nm^2/(kg)^2$ gives $1.989*10^20...

What are some advantages and disadvantages for using an ultraviolet telescope? Why is at better/easier or harder to use a UV telescope than another telescope like a radio telescope or an infrared telescope?
So we have to send them to earth orbit above our atmosphere which filters radiations.Certain objects emit only radiation in UV range.So to study them we have to use UV...
