(1.71 / 197) * 6.023 X 10 ^23 * 79 = 4.154 x 10 ^ 23 AH! and that divided by 100 x the charge is the answer thank you Ryan

79 electrons in a gold atom 1.72/196.96654 = .008732 atoms so .008732 * .79 * 1.602 x 10 ^-19 ?

I'm sure I am missing something simple here but... Suppose a 1.72 g nugget of pure gold has zero net charge. What would be its net charge after it has 1% of its electrons removed? So i know that an electron is 9.109 x 10^-31 kg, and has a charge of -1.602 x 10^-19C. However, how do i know...

Wait... since 1/2L is constant we can count that out...and t = mg so you can cancel out the m being left with .98 = sqrt(g/1) .98^2 = g/1 1-.98^2 = g 3.96%?

So F1 is .96 F0

.96 F = 1/2L * sqrt(t/m) ?

I'm guessing .96F = 1/2L * sqrt(x*T/g) ?

I think that F = 1/2L * sqrt(t/m) I have no clue what to do though

In order to decrease the fundamental frequency of a guitar string by 2%, by what percentage should you reduce the tension? I'm so lost can you point me in the right direction?

Quick physics help please First off, I'm new to the board and want to say hi to everyone! I hope i can give and take from this site, i should be helpful in the chem forums, but physics is not my best. I have 2 quick questions if you could help me that'd be great. A space station is shaped...
