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.

Answer:</h2><h2>
The kite is 186.75 metres from the ground</h2>
Step-by-step explanation:
The length of the string, hypotenuse = 225 m
Angle of elevation, θ = 56°
Sine of an angle is the ratio of the opposite side over the hypotenuese.
Sin θ =
substitute the values in the formula,
Sin 56° =
h = 225 (Sin 56°)
= 225 (0.83)
= 186.75 metres
The kite is 186.75 metres from the ground
<u><em>10:45-12:20=</em></u>
<u><em>1:35 Is the Correct answer</em></u>
