For the first question, number 8 i have put up 2 attachment, one with the question the other one with the answer, I am not sure of the answers however, so if someone can check to see if theyre right or not, and if not show me how to attain the right answer.
thanks
For the next question, number 11, ill just show you the question and do the solution right here.
11)a) f1= 320 Hz
f2=?
f=# of cycles/total time
f=14/7
f= 2Hz (this 2 hz is also the beat frequency)
fb is beat frequency
fb= f2-f1 there's a vertical line for absolute value but i don't know how to type it in
f2= f1-fb
f2=320 + or - 2
f2= 322 hz or f= 318 hzthat was 11a
now 11b11b) f1=320 hz
fb=1 hz(the beat frequency if you looked at question is now 1 instead of previous 2 hz)
fb = f2-f1
f2=f1-fb
f2= 320 + or - 1
f2= 319 hz or f2=321 hzNow how do i know which is the original frequency of tuning fork 2? i don't know what to do next, i don't know which is the right frequency for tuning fork 2.
thanks
