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.

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.

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)...
