3) A 6.1 kg bowling bowl and a 7.2 kg bowling ball rest on a rack. If the force of gravity pulling each bowling ball toward the other is 3.1 X 10° N, what is the separation between the balls?

Explanation:

the formula is given by :

F=Gm'•m"/ r²

where F is the force pulling them towards each other

G is the universal gravitational constant

m'andm" are the masses in contact

and r is the separation between the balls

so we just need to substitute the values and find r ,the gravitational constant is 6.67x10-¹¹. r=Gm'm"/F

b) returns freshwater to the earth.

c) returns freshwater to the earth.c) occurs after condensation.

d) returns freshwater to the earth.c) occurs after condensation.d) roughly equal to the amount of evaporation.

pls mark as brainliest.

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
