According to Kepler's harmonic law, Neptune would have a _________ orbit around the Sun than Mercury.
2 answers:
Slower
Explanation:
Kepler's harmonic law (also called Kepler's third law) states that:
"The cube of the radius of the orbit of a planet around the sun is proportional to the square of its period of revolution"
In formula, this can be written as
where
r is the radius of the orbit
T is the orbital period
const. is a constant number, which is the same for all the planets orbiting the sun
By looking at the equation, we can see that the further a planet from the sun, the larger its orbital period: this means that the further planet will have a slower orbit. In this problem, we have to compare Neptune and Mercury: since Neptune is further from the sun than Mercury, also its orbital period will be larger, and therefore Neptune would have a slower orbit around the Sun than Mercury.

Let t be the time that radial and tangential components of the linear acceleration of a point on the rim be equal in magnitude. At that time we have the angular velocity would be
And so the radial acceleration is
The tangential acceleration is always the same since angular acceleration is constant:
For these 2 quantities to be the same
