If the statement above answers whether the statement is true or false, then the answer is false. It is not true that the echoic sensory memory is used when a lightning bolt flashes across the sky because it does not have that kind of capacity. The echoic sensory memory is the one responsible for the auditory information.
An explanation of sound<span> waves. The pitch of a </span>sound<span> is dictated by the frequency of the </span>sound<span> wave, while the loudness is dictated by the </span>amplitude<span>. When a drum is beaten, the air particles around the drum skin vibrate in the form of a compression wave</span>

Answer:
The more high yield crops are planted, the more production there will be from plants.
Explanation:
High-yield plants are plants that are genetically modified or modified artificially in a way that makes farming plants more efficient. More crops grow, therefore more money.
The answer is, the more high-yield plants there are, the more efficiency there will be from farming.
Answer:
a) f = 809.5 Hz
, b) f = 1619 Hz
Explanation:
The condition for destructive interference from the speakers is
Δr / lam = Ф / 2π
λ = Δr 2π / π
We substitute
λ = 0.21 2 π/π
Lam = 0.42 m
Now let's use the ratio of the speed of sound and the wavelength and the frequency
v = λ f
f = v /λ
f = 340 / 0.42
f = 809.5 Hz
b) in this case the intensity is maximum
Lam = Δr 2π / 2π
Lam = 0.21 m
fF= v / lam
f = 340 / 0.21
f = 1619 Hz
