Answer:
486.76 Hz ; 1460.29 Hz
Explanation:
Given that :
Length of vocal tract = 17cm
Velocity of sound in air = 331 m/s
The first and second formants of the voice ;
First formants :
F1 = V / 4L
V in m/s ; L in m
F1 = (331 m/s) / (4 * 17/100 m)
F1 = (331 m/s) / 0.68 m)
F1 = 486.76470 Hz
F1 = 486.76 Hz
Second Formants :
F2 = 3V / 4L
V in m/s ; L in m
F2 = (3 * 331 m/s) / (4 * 17/100 m)
F2 = (3 * 331 m/s) / 0.68 m)
F2 = 993 m/s / 0.68 m
F2 = 1460.2941 Hz
F2 = 1460.29 Hz
There are many individual and group attitudes and behaviors that can assist a community in maintaining environmental cleanliness.

Lisa does this because generally, when we talk to girls, we usually say things about their appearance, but this only reinforces the stereotypes of beauty in girls who are only cultivating their self-esteem. Because of this, says Lisa, she initiates conversations with the girls about their readings and other questions related to their personal tastes, away from topics as superficial as physical appearance.</span>
