Homework Statement The A string on a violin has a fundamental frequency of 440Hz. The length of the vibrating portion is 31.2cm and has a mass of 0.355g. Under what tension must the string be placed? (Find the answer in the usual metric unit of tension, the Newton, but do not enter...

I don't know the answer yet, its online homework and the professor is rather old and terrible at teaching...

So 6 antinodes.. okay so that would be 6 x V/2L to get the frequency? Is that the equation you would use? Velocity = 39.49 Frequency = 6 x 39.49/2(1.3) which would equal 91.130. So... 39.49/91.130 = .433333 for the wavelength? I need more specificity in your answer please..

Okay so how exactly would I figure out what mode i am in? Is it how many anti-nodes I see, which is 3 I'm guessing, therefore putting it in the 3rd mode? Which would then mean that Frequency would be equal to 3 x v\2L? I'm still not clear on this at all... Okay I took a shot at it... I used...

Not sure how to figure this one out, or where to start: The diagram represents a snapshot of a standing transverse wave on a flexible guitar string taken when the displacement is at a maximum. (Note: the vertical scale is very exaggerated, the actual sideways displacement of the string is...

Hi I am currently doing this problem and ran into a fork in the road- 6ab - 2b2 / 12ab - 4b2 I got .5ab + .5b2 as my answer. Now I am wondering if the second part is right because I am not sure if -2b2 / -4b2 is either .5b2 or just 1.. because the exponents 2-2= 0 and anything with...

ok thanks soo much for your help.. you don't know how much it is appreciated. I will be back many a times probably until about january. let me try - x 2

ok I got .441 meters for the distance which I think sounds right. Almost a half a meter. But could you give me an example of how to do the superscript thing again? Is it [/then the number]? or [#the number#] ? Just show me an example of how you would type it.

for distance I have d = 1/2at (the 't' is squared , but I don't know how to type a small '2' next to it.. if you could show me that too please) this is an equation for the problems where acceleration info is already is included. where initial velocity is included: d= InitialVelocity x (t) +...

after 1 sec it will go 9.8 right? and after .3 sec it will go 2.94.. i think.

Umm.. I said I was stuck. I do not know where to begin at? Help me?

Ok: Note: Acceleration due to gravity: g = 9.8 m/s A feather is dropped inside a vacuum chamber. A) What is the Velocity after 0.30 sec? B) How far has it fallen after 0.30 sec? I'm stuck on this.. it seems simple.. but maybe too simple. I think there is more too it. Any help?
