Answer 9

The standard equation of a sound wave is
y=A*sin(omega*t)

Answer 10

I think ur given equation is
y=(1/4)*sin(2*pi/3)t

Answer 11

Right???

Answer 12

yes

Answer 13

sorry it took me so long to answer os is laggy for me

Answer 14

U wrote theta in ur given equation. I think that was wrong!!!

Answer 15

Here
A=amplitude of wave

Answer 16

Snyway if u compare ur equation with my standard equation u will get
A=1/4
Right?

Answer 17

Omega =2*pi/3
2*pi/T=2*pi/3
T=?

Answer 18

so its 3pie/2 right

Answer 19

theta was in my question man

Answer 20

No

Answer 21

T=3
Right?

Answer 22

idk i have nvr done this before my teacher just dropped it on me and didnt explain what to do

Answer 23

It was
(2*pi)/3=(2*pi)/T
T=3
Right?

Answer 24

Do u need more explaination?

Answer 25

plz
