Question

An all female guitar septet is getting ready to go on stage. The lead guitarist, Kira,who is always in tune, plucks her low E string and the other six members,sequentially, do the same. Each member records the initial beat frequency between her low E string and Kira's low E string.

To tune an instrument using beats, more information than just the beat frequency is needed. In addition to recording the initial beat frequency , each member, exceptDiane, also records the change in the frequency (increase or decrease) when they increase the tension in their low E string.

Rank each member on the basis of the initial frequency of their low E string.
Rank from largest to smallest. To rank items as equivalent, overlap them.

Aiko=3Hz, fbeat increases
Chandra=1Hz fbeat decreases
Evita=5Hz fbeat decreases.
Freja=3Hz fbeat decreases.
Buffy=4Hz fbeat increases.

Answer 1

Answer 2

a) can not be determined

b) buffy, aiko, chandra, freja, evita

Answer 3

Beats frequency is diffrence of the two given frequencies The increase in tension of the string increse its frequency let the frequency that Kira plays isf let the frequency that Aiko plays is beats frequency is increases because of inccrease in tension In the equati onf--3, ifJi increases beats decreases In the equati oni-f 3, ifJ increases beats increases it is given that beats increases Hence the equation Ji-f- 3 is the correct equation Therefore,Jf+3 let the frequency that Kira plays isf let the frequency that Chandra plays isj, beats frequency is f2 increas es because of inccrease in tensio1n In the equati on f --1, ifJ increases beats decreases In the equati on j-f-1, ifJincreases beats increases it is given that beats decrease:s Hence the equation ґ_ґ, 1 is the correct equation. Therefore,J-f-1 let the frequency that Kira plays isf let the frequency that Evita plays isj beats frequency is, Js increases because of inccrease in tensiorn In the equati on f -J-5, ifj increases beats decreases In the equati onJs-f -5, ifj increases beats increases it is given that beats decrease:s Hence the equation f-j3-5 is the correct equati on Therefore,J f-5 let the frequency that Kira plays isf let the frequency that Freja plays is j, beats frequency is , increas es because of inccrease in tension. In the equation,f_ґ,-3, if, increases beats decreases In the equati onj-f - 3, ifJ, increases beats increases it is given that beats decrease:s Hence the equation f - j3 is the correct equation Therefore,f f-3

let the frequency that Kira plays is/ let the frequency that Buffy plays isf, beats frequency is, s increases because of inccrease in tension. In the equati on f - 4, iff, increases beats decreases. In the equati on-f 4, iff, increases beats increases. it is given that beats increases. Hence the equation J,-f 4 is the correct equation. Therefore,s f+4 Hence ranking from largest to sm allest: In the order of their names is: Buufy>Aiko>Chandra>Freja>Evita
