windows audio is at max. and after checking carefully, i cans till hear the hum from the integrated speakers on the laptop. so its not an external problem. its just because the external speakers are louder.

Hi, when i plug my speakers into my laptop, i can hear a slight whining sound from one of the speakers. i assumed it was the speakers, however i plugged some brand new headphones in, and the same problem occurred. this leaves me to believe it is a problem with the laptop. does anyone know why it...

ah ok. thanks for the help. like i said above, do you have a directory on this site, or know a link to one, of all the thermodynamics equations?

Oh i see, use pv = nRT to work out n. ok, so from n = PV/RT, am i right in assuming the values of p, V and T are the differences? n = pV/RT so n = (2850000 x 3)/(8.314 x 35) n = 29382.45 m = nM so m = 851150.9 Im sure this is wrong as it seems too large.

what is n though? is this not a constant? i am not given it in the question
