## anonymous 5 years ago F=time generating force felt by the earth due to another object in space. m1=mass of the earth=5.98x10E24kg m2=mass of the in space R=distance between the earth and object (in meters) G=universal gravitational constant=6.6720x10E negative11 mE3/kg*sE2 a=radius of the earth=6400km

1. anonymous

F=2GM1M2a/R E3 This is the formula

2. bahrom7893

hey ill answer here, my formula as well as urs was wrong

3. bahrom7893

Okay so in the case of the moon and earth: Mm = 7.42x10^22 Me = 5.98x10^24 G = 6.6720x10^-11 a = 6400km = 6,400,000m Rm = 3.840x10^5km = 3.840x10^8m Plug them all into the formula.

4. bahrom7893

$F = (2G \times M_1 \times M_2 \times a )/R^3$

5. bahrom7893

F = 6.69233 x 10^34 N

6. bahrom7893

can u check the answer?

7. bahrom7893

that's for the moon part

8. anonymous

no my calculator not working...

9. bahrom7893

Oh well basically that's the formula u plug that into. Mm and Me are masses of moon and earth and are equivalent to M1 and M2

10. anonymous

is it Me or M1

11. bahrom7893

doesn't matter use whichever u want. I prefer Msube

12. anonymous

ok lets see if i get answer..

13. bahrom7893

for the sun part just replace Mm by Ms and Rm by the distance from sun to earth. convert to meters from kilometers

14. anonymous

is it 5.87 idk not sure..

15. bahrom7893

is what 5.87?

16. anonymous

17. bahrom7893

lemme check my work

18. bahrom7893

hey can u start a new topic and post the following values: Mass of earth Mass of moon Mass of sun Distance b/n earth and moon Distance b/n earth and sun Universal grav. constant Radius of earth, im tired of lookin thru the posts to find values

19. anonymous

well im sorry, it is a lot of work i just don't know how to even do this.

20. anonymous

im lost

21. bahrom7893

the numbers u gave me earlier

22. bahrom7893

oh wow lol nevermind, im sick of this problem and i hate it if i cant solve something, ima do that myself.. watch out for a new topic with ur name

23. anonymous

sorryyy. i hate these math questions:///
