The biosphere is best described as the regions of earth that support a. plant life b. animal life c. all life d. human life

Explanation:

Refer to the pic below that I attached as we talk through these answers.

The amplitude is shown as the height from the top of one wave (called the crest) to the midline. If the whole vertical height from crest to trough is 32 cm, then the amplitude is half of that at

A = 16 cm

The wavelength, or λ, is the horizontal distance from crest to crest or trough to trough. Therefore, our wavelength is 48 cm + 48 cm which is

λ = 96 cm

The speed of the wave is the same thing as the velocity of the wave which can be found in the equation

where f is the frequency of the wave and lambda is the wavelength. Filling in:

and

2.4(96) = v so

v = 230 m/s to the correct number of sig fig's
