Question

-An all female guitar septet isgetting ready to go on stage. Thelead guitarist, Kira,who isalways in tune, plucks her low E stringand the other six members,sequentially, do the same. Each memberrecords the initial beatfrequency between her low E string andKira's low E string.


*Rank each member on the basis of the initialfrequency of her low Estring.
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. PLEASEHELP 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 thefrequency of her string, her initial frequency must be less thanKira's. There are other players who have greater frequencies thanKira.

Theres no box for Kira so i cannot rank her in the problem..how doi do this??
