Answer:
chemical energy
Explanation:
Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.

Human capacity is the ability of an individual to do or accomplish a certain task based on the individual's knowledge, skills and abilities, moreover, the person's overall intelligence, emotion and affect, personality, characteristics and behavior on a particular task.
Human capacity is greatly subjected to the person's either biological, psychological and mental state which can influence the person's drive, motivations, goals and response which guide and reflect his overall performance.

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.
