Answer:
Number of years for the asteroid to make one revolution about the sun is 2.83 years
Explanation:
The square of the period , T of any planet in a circular orbit with radius, r is given by:
T^2= (4pi^2/Gm) × r^3 ...eq1
For earth,T^2earth= (4pi^2/Gm) × r^3 ...
eq2
Where m is mass of the sun
Divide eq1 by eq2 , you get:
T^2/T^2earth = (r/rearth)^3
Substituting r=2reath , we get:
T^2/T^2earth =( 2rearth/rearth)^3
T/Tearth = Sqrt(8)
T/Tearth= 2.83
The period the earth revolves around the sun is 1 year
T/1 = 2.83
T= (1 × 2.83)years
T = 2.83 years
Given the index of refraction, n and speed of light in the vacuum, c, we can solve for the speed of light in the transparent substance by the equation below.
n = c / v
where v is our unknown.
Substituting the known values,
1.7 = (3 x 10^8 m/s) / v
The value of v is equal to 1.76 x 10^8 m/s.
There are three things needed to be classified as a planet.
Pluto meets 2 of the 3.
The one it does not meet is it doesn’t “clear the neighborhood” which means a planet needs to be gravitationally dominant over all objects around it. Meaning smaller bodies ( asteroids) would either combine with the larger body making it bigger or pushing them away ( out of their orbit) so they do not collide with the larger body.
