G question, An asteroid is discovered in a nearly circular orbit around the Sun, with an orbital radius that is 3.83 times Earth's. What is the asteroid's orbital period T , its "year," in terms of Earth years

Therefore the asteroids's orbital period is 7.45 years.

Explanation:

Kapler's third law:

The orbital period of a planet squared is directly proportional to  the average distance of the planet from the sun cubed.

T = orbital period of the planet

r = orbital radius of the planet

Here = Orbital period of the asteroid

= Orbital radius of the asteroid

 Orbital period of Earth = 1 year

=Orbital radius of Earth

Given that the orbital radius of asteroid is 3.83 times of orbital radius of Earth.

Therefore

   [ 1 year]

Therefore the asteroids's orbital period is 7.45 years.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

your answer is c! hope this : )
