And furthermore as a followup question for question 23, given that we were able to calculate the frequency to be 20Hz and the velocity would be 0.8m/s, could we not find velocity using v=f(wavelength) and rearrange for wavelength?
This video is super helpful thanks! I was confused while working on the last problem part (c). taking square root of (5N/(0.05kg/m)), I got 10m/s for the speed. Why do I get the different answer from yours?
Hoping to get a response. In question 22 shouldn't the correct solution be 0.8m/s, as you move a total of 0.02m in 0.025s as from 0s to 0.0125s you travel 0.1m, but from there back to the "x axis" you travel another 0.01m and so over 0.05s you travel 0.04m and 0.04/0.05=0.8?
This was very helpful in clarifying wave concepts. Thank you!
Great job

GOAT FOR REAL
Practice problem 8 isn't the answer 29000m/s
Nop
Multiply the 725 by 0.40
Why 0.40 coz the wavelength is measured in meters and its 40m already @@IvyMathonsi
