Answer:
The given steps are of light phase of photsynthesis.
1)A photon of light excites photosystem II.
2)A water molecule is split, the electrons are transferred to photosystem II.
3)Oxygen is formed as an endproduct.
4)An electron is transferred from photosystem II to the primary electron acceptor.
5)ATP is synthesized as the electrons pass through an electron transport chain to photosystem I.
6)A photon of light strikes photosystem I, an excited electron is transferred to the primary electron acceptor.
7) An electron is transfered from an electron transport chain from photosystem II to photosystem I's primary electron acceptor.
8)Electrons are passed from photosystem I through an electron transport chain.
9)NADP+ is reduced to NADPH.

Answer:
b. 457 Hz
Explanation:
Things including sound move like waves in the air. The distance between the crest of those waves is known as the wavelength, denoted by lambda (λ).
The wavelength of a sound can be calculated using the formula: λ = c/f
Where; λ= wavelength
c = speed of sound
f = frequency of sound
According to the question;
Wavelength of sound (λ) = 0.750m
Speed of sound (c) =342.5m/s
To calculate frequency (f), we make f the subject of the formula in λ = c/f
We initially cross multipy to have; c = λf
Divide both sides by λ to have; f = c/λ
We then calculate by inputting our values into the formula: f = c/λ
f = 342.5/0.750
f= 456.66
Approximately, the value of the frequency of the sound is 457Hz.
