Now this is coming close to its due date, please check! :)

A little bump, just want to know if this is correct!

Also i did not convert hours into minutes, as i finally was able to contact my teacher who said to leave it in hours!

here is the table

Homework Statement Hey guys, I just want you to check out my homework before I send it off! First of all, I attached a table in which I was required to come up with “Time per mode of transport” and “Total time to reach final destination” I included my answers right on the table in the...

Perfect, thank- you so much!

So do you think there is any reason to convert it to minutes? I do not know if i should or not as the question does not indicate whether it should be in hours or minutes. See the 31/90 is 31km/90km/h to find the total time per mode of transport. In the first cause you said that 0.34 is the...

Homework Statement Here is a few examples where i am wondering as to how many significant digits to leave 3.5L/100km * 2279km = 79.765 ---> In this case am i supposed to round to 2 significant digits because of 3.5 which has two? 1.2L/100km * 63km = 0.756, i leave it as 0.76 right...

B. The wavelength shortens and the frequency increases/ temperature of course stays the same! Did i get it right? Thanks for verifying my answer for A.:)

I think the frequency is supposed to be 320.37Hz instead of 320.4Hz. From reading into this, it appears that i do need to use f3 = 3f1 or f3=3v/2L to find the third resonant length frequency, which would give me 961.11Hz. Is this correct? Still not sure about B)

Homework Statement Hollow tube chimes are made of metal and are open at each end. One chime is 0.54 m long. A) if the speed of sound is 346 m/s, what is the frequency of sound produced by the third resonant length? B)What would happen to the frequency of sound produced by the third...

Sorry i was sleepy when i read your post the first time, totally got it now! I was just overcomplicating things! Thank you

So what answer for B am i supposed to write then? The first or the second? There is a big difference between 33-66! Phyzguy said that speed is always equal to the frequency times the wavelength, therefore the answer that am i supposed to use is the first one i wrote? How can the yahoo answer be...

Fundamental Frequency (String Resonance) - velocity problem! Homework Statement Hey guys, i just started working on Fundamental Frequency but am getting confused! A string that is 6.0m long is vibrating with three loops in it. The frequency of the source is 16.5Hz. A)What is the...
