17. an asteroid orbits the sun at a distance of 2.7 au. what is its orbital period?

T = 4.44 years.

Explanation:

The third law, also known as harmonic or period, relates the periods of the planets, that is, what it takes to complete a round around the Sun, with its middle radii.

For a given planet, the square of its orbital period is proportional to the cube of its average distance from the Sun. That is,

T^2=k⋅r^3

Where:

T: Period of the planet. Its unit of measure in the International System is the second (s)

k: Proportionality constant. Its unit of measure in the International System is the second squared cubic meter match (s2 / m3)

r: Average distance to the Sun. Due to the properties of the ellipse, it is satisfied that its value coincides with that of the semi-major axis of the ellipse, a. Its unit of measure in the International System is the meter (m)

answer; in the united states the plains include the great plains of the west and the tail grass prairie to the south of the great lakes extending east to the appalachian plateau

lol i would say c -porductivity
