Answer:

positive direction with a changing velocity. An object which moves in the positive direction has a positive velocity. If the object is slowing down then its acceleration vector is directed in the opposite direction as its motion (in this case, a negative acceleration

Solar winds have an influence all the way to about 160 AU from the Sun. About how many kilometers is that?
Mumz [18]

Answer: A. 24,000,000,000 km

Explanation: An Astronomical Unit  commonly abbreviated as AU is the average distance between Earth and the Sun and is about 150 million kilometers.

Astronomical unit is mainly used to measure distances within our solar system.

1 AU is equal to  150\times 10^6 km

Thus 160 AU  is equal to \frac{150\times 10^6}{1}\times 160=24000\times 10^6km=24000000000km

Planet RMM-1 has a mass of 28,500 kg and the star it revolves around has
SOVA2 [1]

Gravitational force = G · (mass₁) · (mass₂) / (distance)

(distance²) = G · (mass₁) · (mass₂) / (Gravitational force)

G = 6.67 x 10⁻¹¹ n-m² / kg²  (the "gravitational constant")

Distance²  = (6.67 x 10⁻¹¹ n-m² / kg²) (28,500 kg) (2.2 x 10⁸ kg) / (39 N)

Distance² = (6.67 · 28,500 · 2.2 x 10⁻³ N-m²) / (39N)

Distance²  =  (418.209 N-m²) / (39N)

Distance²  =  10.72 m²

<em>Distance = 3.275 meters</em>

An absurd scenario, but that's by golly what the math says with the numbers provided.  I guess it's a teeny tiny planet orbiting 3.275 meters outside a teeny tiny black hole.
