Nevermind, got it!

Homework Statement A straight horizontal garden hose 28.0 m long with an interior diameter of 1.30 cm is used to deliver water at the rate of 0.610 liters/s. Estimate the pressure drop (in Pa) from one end of the hose to the other. The coefficient of viscosity for water is 1.003E-3 Pa*s...

i actually had to find two frequencies using too different equations because the sound bounces off the black board and moves towards the observer. Also, when he moves away from the observer. Solved them equations and found the beat frequency

Noone?, again.. I figured outthe beat question.

Homework Statement Hillary stands directly in front of speaker S1 and walks straight away (down on the page) from S1 as shown in the diagram. What is the first distance (measured from S1) at which she will hear minimum loudness? Speed of sound is 343 m/s and the frequency of the sound is...

"moves away from you and towards the blackboard ", so the source being the teacher is not moving towards you(observer) he is moving away from the observer in this problem... Even if he was moving towards you that still equals 465Hz which would result in a 5.0Hz beat frequency.

Noone?

Homework Statement A man strikes a 460. Hz tuning fork and moves away from you and towards the blackboard at a constant velocity of 3.80 m/s. What beat frequency do you hear if the velocity of sound on that day is 340 m/s? Homework Equations The Attempt at a Solution Since...

Makes so much sense... this problem was really not that hard. :redface:

Also, in the above equation with the workings I had (15/x) not (x/15)^2, so i could have figured it out using this method and the other method correct?

53.2 m! i got it after, that was the right answer...appreciate the help! once i get frustrated with a problem i shut down..ill have to make sure i understand what's going on in this for future exams !

square root =3.55+15=18.6..

(1.99*10^-7)=(15/x)^2 * 2.51 * 10^-6 7.93*10^-14=(15/x)^2 6.29*10^-27=15/x r2(x)= 2.38 *10^27...large number something is wrong

x=vs*ts x=vp(ts-tp)

x=Vs(ts-tp) x=Vp(tp+78.8)
