Well that's Vt=w*r, but i don't see how you obtain that from given just frequency and radius. Is their a formula that that will help get me started. Heres some formulas including w. k=w/v w=2*pi/T But none of these help, yet atleast

Homework Statement A siren has two loud speakers attached to a rotating disk. The disks radius is 3m. The speakers emit a sound frequency of 300 Hz.(Speed of sound in air is 344 m/s) A)How fast does the disk need to spin for an observer standing some distance away to perceive two frequencies...

I'm having a problem determining the upper and lower halves of a karnaugh map when trying to design a counter using flip flops. So where I am at is, taking a 4 bit table with the next state included, putting it into a next state map and then in the J-K, and S-R flip flops tables. I know the...

1. Where did i go wrong, please explain. Homework Statement The Horizontal Venturi pipe has a cross sectional area of 50cm^2 at the wider portions(A_1) and 25cm^2 at the constriction(A_2). Air density of 1.29 kg/(m^3) is flowing in the pipe. there's a attachment of a picture to reference...

MatLab "for" loops Homework Statement Write an m-file to evaluate y(x)= x^2 - 3x +2 for all values of x between -1 and 3, in steps of .1 . Do this twice, once with a for loop and once with vectors. Plot the resulting functions. Homework Equations The Attempt at a Solution...

Ya, several people i talked to have a problem with this question because it seems so vague. But what i think the question is asking for is basics of this problem, not accounting for everything, which doesn't make much sense in the end.

Bouyancy Question: A 3000m^3 submarine of mass, m, is filled with air(density air =1.29kg/m^3) and is floating, submergerd, in seawater(density = 1400kg/m^3) a) draw diagram. b) Write an equation that that equates weight of the sub to the buoyant force( include weight of air)? c)...
