Barycenter can be described as? ? a) the center of a celestial objectb) the point between 2 objects that is in the exact center3) the point between 2 objects where they balance each other

3) the point between 2 objects where they balance each other

Explanation:

The center of mass of two bodies about which the bodies orbit and balance each other is known as Barycenter. It is the point of balance of two or more celestial bodies. The Barycenter determines the orbit of the celestial bodies.

For example: the binary stars orbit a common center of mass. Pluto and its moon Charon revolve about their Barycenter.

Hence, the correct option is 3.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
