Answer:
26dB
Explanation:
The decibel level β is a calculated by 10log (I/Io)
Where I and Io represent sound intensity
From the question, there's no interference. So
Where I = 4Io (because there are 4 men shouting), so the intensity will be 4 times larger.
β = 10log (I/Io)
β = 10log (4Io/Io)
β = 10log 4
β = 6.020599913279623
β = 6 ---- Approximated
The decibel level = 20 + 6.020599913279623
Decibel Level = 26.020599913279623
Decibel level =26dB --- Approximated
Answer:
Specifically, rest is essential for muscle growth. Exercise creates microscopic tears in your muscle tissue. But during rest, cells called fibroblasts repair it. This helps the tissue heal and grow, resulting in stronger muscles.

answer to this question is Endocrine System. Endocrine System consists of
different glands that discharge hormones directly to the circulatory system
like the heart, blood, blood vessels. The hormones that are secreted by the
endocrine system helps developed or body. The endocrine system consist of major
glands which are the hypothalamus, pituitary glands, thyroid, adrenals,
reproductive organs, parathyroid, pineal glands, and the pancreas. </span>
<span>A muscle contraction that results in no movement of the body is referred to as an isotonic contraction. The isotonic contraction can be </span>concentric and eccentric. C<span>oncentric </span>contraction results in the muscle shortening, because the force the muscle is producing is greater than the resistance. Eccentric isotonic contraction on the other hand results in muscle lengthening because<span> the resistance is being greater than the force the muscle is producing.</span>
