"The moon takes about 27.3 days to revolve around the earth in a nearly circular orbit of radius 3.84×10^4 Km. Calculate the mass of the earth from these data"
Added by Himi R.
Step 1
First, we need to convert the time the moon takes to revolve around the earth from days to seconds because the standard unit of time in physics is seconds. There are 24 hours in a day, 60 minutes in an hour, and 60 seconds in a minute. So, 27.3 days is equal to Show more…

The moon takes about $27 \cdot 3$ days to revolve round the earth in a nearly circular orbit of radius $3 \cdot 84 \times 10^{5} \mathrm{~km}$. Calculate the mass of the earth from these data.
Determine the mass of the Earth from the period $T$ and the radius $r$ of the Moon's orbit about the Earth: $T=27.3$ days and $r=3.82 \times 10^{5} \mathrm{~km}$.
The moon takes about 27 days to orbit the Earth once, at a distance of about 385,000 km. We can use this information to also find... the radius of the moon the mass of the moon the radius of the Earth the mass of the Earth the mass of the sun
