a is at the midpoint of the first wire, C is at the midpoint of the second wire...what is the equation?

A is at the midpoint of the first wire... A I <--------------------- --------------------->10A C

need help asap...by 2:30 :( if 2 parallel conductors with the same length of .05m have their currents going in opposite directions, one conductor carries a current of 10A. C=D/3, D=24cm, I is adjusted so the magnetic field @ C=0. a. find the value of the current I b. value of magnetic field @...

Homework Statement compared to the speed of 100Hz sound the speed of 200Hz sound through air is? Homework Equations i thought i needed the temp of air to fiigure this question out, but the temp is not given? is this question as simple as 200/100 or no?? The Attempt at a Solution...

Homework Statement A 3.0 organ pipe is open at both ends. The velocity of sound is 331 m/s. What is the wavelength of the lowest frequency? Homework Equations am i missing something...i need a lil help here! The Attempt at a Solution wavelength=2L/n fn=V/wavelength(n)=n(V/2L)=nf1...

sound wave of a source?? Homework Statement A sound wave radiates from a source to all directions, if the power of the sound is 200 watts then the intensity of the sound wave 100m from the source is what? Homework Equations is this question complete / incomplet? is it missing any...

Thermal Expansion 25cm brass rod, alpha of brass 19.0 *10^-6, temp change 20-25, what is the increase in length of the brass rod? WHAT FORMULA IS THIS??

because someone told me i could not do that and no one would help me if i did that?? will u help me?? the problem is... the bulk modulus of water is 0.210x10^10n/m^2 and the density is 100 kg/m^3. What is the velocity?

sqr. root (0.210*10^10 n/m^2/100kg/m^3) ?

ok i have that in terms of v= sqrt of. a measure of the restoring force (B) / a measure of the inertia (p) but sqrt (0.210*10^10/100) is not giving me the answer i need ?? am i missing something?

bulk modulus if you know bulk modulus and density how do u find the velocity?

what is the formula to solve this equation?? 1. A sound wave radiates from a source to all directions, If the power of the sound is 200 watts, then the intensity of the sound wave 100m from the source is?

not homework questions...study questions for a test which i have no idea how to do...can someone help me with some equations or something? if not, DONT REPLY! thanks

Sound & Temperture Questions? please help me! 1. A sound wave radiates from a source to all directions, If the power of the sound is 200 watts, then the intensity of the sound wave 100m from the source is? 2. The bulk modulus of water is 0.210 x 10^10 n/m^2 and the density is 100 kg/m^3...
