Distance=2m
because 200cm = 2m
so 4m-2m=2m
Answer:

Answer:
70 m.
Explanation:
Given,
Frequency, f = 20 HZ
speed of sound, v = 1400 m/s
wavelength of the waves = ?
we know,
v = f λ



Hence, the wavelength of the wave is equal to 70 m.
Wind<span> power
holds great promise for the united states because of the great wind power (capacity),
and experts believe wind energy could meet as much as 20 percent of the
nation’s energy needs
. Texas is the state with most wind capacity. On the second place is Iowa and oh the third place Oklahoma. The wind farms produce clean energy that does not harm the environment.</span>
