oh ok, that was exactly what i thought it was thanks

[SOLVED] Standing Sound Waves What are the three longest wavelengths for standing sound waves in a 121 cm long tube that is (a) open at both ends and (b) open at one end, closed at the other? the wavelength equation that i used for open-open was \lambda= 2L/m; where m is the number of...

well i always start out by listing what i know about the situation, and then list what i want to know. That way i have a clear mind of what I am looking for, do that first and then attempt to solve it

oh wow that was easy, i always see things harder then they are, thanks terbum

[SOLVED] Gauss's Law and Flux ok so i have the biggest question of all i tried solving the following problem: 55.3 million excess electrons are inside a closed surface. What is the net electric flux through the surface? now i tried the following equations: \Phi= E . A = Qin/\epsilon...

WOW thanks this really helped me i didn't knew that the temperature didn't affect the atmospheric pressure, i solved it thanks

yeah i took a look at that but because the temperature is higher than STP i don't know density or mass

any info or help is appreciated, anything cause i have no idea if that process is right

(SOLVED)Thermodynamics & Thermal Energy Homework Statement a 6.0m X 8m X 3m room contains air at 20 Degrees Celcius Homework Equations What is the room's thermal energy The Attempt at a Solution now i know that oxygen is a diatomic atom so i used E(thermal)= 5/2...

ok i understand all of it, but i have one last question how can i find the perpendicular distance of the line to the pivot? Thanks for all your help

yea that's the part i didn't get, i mean i know there is 2 torques that's why i thought of the equation above, but besides that i didn't understand anything else t=rFt but i don't have the force either and they only gave me mass and distance, so I am unsure on what step to take next
