The G string of a guitar which should be 392 Hz is playing flat at 380 Hz. What percentage change in the tension of the wire is required so as to tune the string to 392 Hz

causes

fossil fuels burn

cities become more industrialized

human population grows worldwide

98.4 m

explanation:

let s = distance up the plane  

then by conservation of energy  

1/2m(18.3)^2 = mg s sin(10)  

(18.3)^2 = 2g s sin(10)  

s = (18.3)^2/2gsin(10)  

= 98.39564526  

= 98.4 m
