Answer:
D
Explanation:
biotic means living and out of the options the only thing living in the environment is a flower.
The frequency of the wave is 0.196 Hz
<h3>Speed of a wave</h3>
The speed of a wave is given by v = fλ where
- f = frequency and
- λ = wavelength
<h3>Frequency of the wave</h3>
Making f subject of the formula, we have
f = v/λ
Since
- v = speed of wave = 4.5 km/s = 4.5 × 10³ m/s and
- λ = wavelength = 2.3 × 10⁴ m.
Substituting the values pof the variables into the equation, we have
f = v/λ
f = 4.5 × 10³ m/s ÷ 2.3 × 10⁴ m.
f = 1.957 × 10⁻¹ Hz
f = 0.1957 Hz
f ≅ 0.196 Hz
So, the frequency of the wave is 0.196 Hz
