Answer:
3) 0.75m/s
Explanation:
The wavelength of a wave is calculated using the formula;
λ = v/f
Where!
λ = wavelength of wave (m)
v = velocity or speed (m/s)
f = frequency of wave (Hz)
According to this question, one end of a rope is vibrated to produce a wave with a wavelength (λ) of 0.25 m and frequency (f) of 3.0 Hz.
Using λ = v/f
v = λ × f
v = 0.25 × 3
v = 0.75m/s.
i think its more intense light, absorbed more carbon dioxide, and absorbed more oxygen
In the military strategy of the south the army remains effective, and mobile before an enemy that is stronger to wear it off over time. The plan of the military strategy of the north has three steps: the Union called for the blockade of the south coast, the capture of Richmond, the capture of Mississippi R. With this plan they toppled the south.
The advantages of using mixed method are, the pros and cons can be identified and compared for each method. Thus option B is correct.
<h3>What are advantages of using mixed method?</h3>
Mixed methods in research is an advanced form which is basically a combination of quantitative research and qualitative research.
It can help the researcher to gain a more clear and complete picture as it integrates benefits of both methods.
Mixed methods research is used in the behavioral, health, and social sciences, societal research.
Qualitative research has smaller sample size, so mixed methods research is applied for the comparative strength of externally valid quantitative research.
Mixing methods allowed to get findings in detail to the conclusion.
Using mixed methods from different data on same subject can give more credible results.
Thus option B is correct.

Answer: Decrease
It will decrees because required volume of blood will not be emptied into the pulmonary circulation to reach the lung for oxygenation. Rather blood flows back into the Right atrium ,(regurgitation,) through the these valves during ventricular contraction ( systole)of the Right Ventricle instead to the pulmonary circulation which reduces blood flow leading to volume overload in the heart. Eventually this affects systemic circulation,
