Answer 30

Upon which does the amount of gravitational pull between two bodies depend?



A.


only the mass of the smallest body


B.


the masses of both bodies


C.


only the mass of the largest body


D.


the speed by which they orbit

Answer 31

Gravitational pull formula is \[\frac{ M1M2 }{ r^2} \] multiplied by 6.686 x 10^n power.
Can you figure it out now?

Answer 32

no thisa is the 1 problem i dont know or have an idea
could you plz just gimme the solution for this one

Answer 33

M1 is mass of first object M2 is mass of second object

Gravitational pull or force=\[\frac{ M1M2 }{R^2 }\]
multiplied by a constant.

Answer 34

R is just distance.

Answer 35

so?

Answer 36

what does gravity rely on based on those formula?

Answer 37

M1 is mass of first body.
M2 is mass of second body

Answer 38

the mass? of both bodies?

Answer 39

You need those formula to figure out the gravitational pull.

Answer 40

Yes that is correct!

Answer 41

Gravitation pull happens everywhere between every bodies.

Answer 42
