## anonymous 5 years ago can anyone help with my questions its physics???

1. bahrom7893

i can try

2. anonymous

ok do you get my question

3. bahrom7893

yes and i said i can try.. aka i can try to help, post the question then we'll see

4. anonymous

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

5. anonymous

So what are you looking forr???

6. anonymous

F=2GM1M2a/R E3 This is the formula

7. anonymous

ok well i have to calculate the tide generating force due to the sun and the force due to the moon

8. anonymous

i have to use the following numbers:

9. anonymous

Mm=mass of the moon=7.42*10E22 kg Ms= mass of the sun=1.83*10E30 kg Rm= distance between the moon and earth= 3.840*10E5 km Rs= distance between sun and earth=1.495*10E8

10. anonymous

E means exponent

11. bahrom7893

can u post the formula the regular way? its kinda confusin this way, via insert equation?

12. anonymous

i can't do it that way.... but it is F=2GM expo1 M expo2 a/ R expo3

13. bahrom7893

$F = [(2G)M^{1}M ^{2}\times a] / R^3$

14. bahrom7893

Like that?

15. anonymous

yes (:

16. bahrom7893

okay afk...

17. bahrom7893

m2=mass of the in space -- mass of the what?

18. bahrom7893

And im sure ur formula is wrong. This is the right one: http://upload.wikimedia.org/math/0/f/3/0f36df929ac9d711a8ba8c5658c3bfee.png

19. anonymous

mass of the object that is the formula they gave us

20. bahrom7893

Im sure u copied it wrong! It is Msub 1 and Msub 2, the universal gravitaional constant formula!

21. anonymous

ok i probly did. does it make sense with ur formula??

22. bahrom7893

yeah

23. anonymous

ok think it is that one

24. anonymous

did u figure out the problem?

25. bahrom7893

workin man

26. bahrom7893

and my equation was wrong too

27. anonymous

girl, but ok sorry keep helping me thanks so much

28. bahrom7893

k lol sorry
