-An all female guitar septet isgetting ready to go on stage
-An all female guitar septet isgetting ready to go on stage. The lead guitarist, Kira,who isalways in tune, plucks her low E string and the other six members,sequentially, do the same. Each member records the initial beatfrequency between her low E string and Kira's low E string.
*Rank each member on the basis of the initialfrequency of her low E string.
1) Aiko
F BEAT=3 Hz
=decrease
2) Chandara
F BEAT=1 Hz
increase
3) Euita
FBEAT= 5 Hz
= decrease
4) Buffy
= 4 Hz
FBEAT= increase
5) Freja
FBEAT= 3 Hz
= decrease
-or cannot be determined
NOTE: THE ANSWER ISNT (IN TERMS OF PEOPLE INITIALS) Evita,Aiko=Freja, Chandra ,Buffy / OR THE OTHER WAY AROUND. PLEASE HELP ME, IT NEEDS TO BE TURNED IN TOMORROW! AND I AM SO LOST.
this is the hint the computer gave me when i entered in E,A=F,C,B : Since the beat frequency decreases when Evita increases the frequency of her string, her initial frequency must be less than Kira's. There are other players who have greater frequencies than Kira.
Expert Solution
I am assuming that the increase or decrease is when the players increase the frequency by tightening their strings.
Beat frequency is just difference, we don't know if you note is high or low unless you tighten (or loosen) the string and see if the difference gets smaller or larger.
Aiko tightens her string and the beats decrease, so she is flat and getting closer to perfect.
Dr. Chandra tightens the string and his beat frequency increases, so he is sharp getting sharper.
Evita starts with a big difference and it decreases, so she was flatter than anyone so far.
Buffy was off by a lot and when she tightens her string she gets close to the right note, so she was the flattest.
Freja was off by three and the frequency decreased when she tightened her string, so she was flat.
Now lets rank the numbers
Aiko 3 flat
Chandra 1 sharp
Evita 5 flat
Buffy 4 sharp
Freja 3 flat
So, here is the order
Lowest (Flattest) Evita, Tie between Aiko and Freja, Chandra, Buffy
With Kira perfect and right before Chandra
