. A wave of sound that has a wavelength of 20 meters, and a frequency of 25 Hertz travels through the air. As it falls in water the same wave starts traveling faster at 1500 meters per second. What is the new wavelength of the wave? please answer my otger question plesase ill give brainlist orwhat ever the fwack it called​

half of a circle

explanation:

the arrow and the top of the circle is matching together. it is not a polygon because a polygon would always be the same shape. therefore, an half of a circle is called semicircle so you would find the radius of it.

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day

because growing process had stoped after 4-5 year

a=d/t

a="triangle"v/t

explanation:

a = acceleration
