acceleartiononmoon= GMassmoon/radius^2 =G 7.35E22/(1.74E6)^2= G 2.43E10= = 6.67E-11*2.43E10= 1.62 m/s^2 or as a gravitational field constant= 1.62 N/kg I have no idea why you used the mass of Earth. were did you get a = r^-2 Gm from i thought that the equ...

makes sense to me but is my answer also correct?

huh interesting well thanks my only last question is what's is the point of us SRform? I undrestand that in some rare cases you might not have a calculator but in most cases you will... but anyways using SRform is to simplify when you don't have a calcula...

=0.254... I see why I get this but I don't think I'm suppose to get an answer that has a lot of digits correct?

yah but i have to do it with out a calculator it's SRform right has to be done without calculator?

how come when I put into my calculator (sqrt5 - sqrt 3)^2 i get .2540333076 not 5-3 or simply 2...?????????

I do see however when I put into my calculator (5^(2^-1)-3^(2^-1))^-1(5^(2^-1)-3^(2^-1))^-1^-1 I get one in the denomenator which is not what I'm trying to do?

everything made sense I just don't see why .5 m must be half a wave length

Also is the 343 hz the first harmonic or what is it because I know once you find the fundemental then the first harmonic is just simply twice the fundemental and the third harmonic is just simple three times the fundemental frequency... I'm doing 343*3 to...
