When the distance between two stars decreases by one-third, the force between them

the force increases by 9/4

Explanation:

The gravitational force between two stars is given by:

where

G is the gravitational constant

m1 and m2 are the masses of the two stars

r is the separation between the two stars

In this problem, the distance between the two stars is decreased by 1/3, which means that the new distance is

So, the new gravitational force will be

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)
