<em>number of waves that pass a given point in one second is called <u>frequency..</u></em>
Answer:
v = 3200 m/s

wavelength of the sound wave is given as
so now we have
so we will have
They did not believed Galileo's discoveries because religiouse reasons the preast said that all the bible is true but Galileo despised it.
You already have the speed, now you need the time.
I will use the formula for speed which is S=D/T.
S=Speed D=Distance T=Time.
So here we have, 18m/s = 52m/T
we do 18 divided by 52 which would be .3461.
.3461 seconds is how long it took the stone to reach the water.
