The answer to your question is 164 !!!
ok well first you would find what the square root would be then you just see where it falls on the number line
so the sqrt of 29 is 5.38516... so it falls between 5 and 6.
so the answer is 5 and 6
The Neptune's time period of orbit is 164.3 earth years.
We have given that the mass of the sun is 2 × 1030 kg.
The distance between neptune and the sun is 30 au
<h3>What is the mathematical expression of Kepler's law ?</h3>
Where T is in earth years, a is astronomical units and
M = solar masses.
4π²/GM = 1,
Therefore we get
Therefore, the Neptune's time period of orbit is 164.3 earth years.
