AI Thread Summary
Dogs can hear frequencies much higher than humans, making dog whistles effective at 30,000 Hz, which is inaudible to people. To find the wavelength of the sound emitted by the whistle, the speed of sound in air is needed, typically around 343 meters per second. The equation to use is speed = frequency × wavelength, but without the speed, the calculation cannot be completed. The discussion emphasizes the importance of knowing the speed of sound to solve the problem for the upcoming quiz. Understanding these concepts is crucial for accurately determining the wavelength of a dog whistle.

Homework Statement


Dogs are able to hear mucher hgher frequencies than humans are capable f detecting. For this reason, dog whistles that are inaudible to the human ear, can be easily heard by a dog. If a dog whistle has a frequency of 30,0000 Hz, what is the wavelength of sound emitted.

Homework Equations





The Attempt at a Solution


Well I was trying to find the wavelength using the equation speed=Hz(Wavelength) but I don't have the speed. So I am really lost. If
anyone could guide me in some helpful equations I might need, because I have a quiz on this tomorrow

Are you sure the book/excercise you got the question doesn't give you the speed?

Yea positive. Checked it twice that's why I was confused.

Maybe I have to know the speed of sound through Air?

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
