Amplitude is a measure of the size of sound waves. It depends on the amount of energy that started the waves. Greater amplitude waves have more energy and greater intensity, so they sound louder. ... The same amount of energy is spread over a greater area, so the intensity and loudness of the sound is less.
Answer
given,
k = 250 N/m
q = 900 N/m³
(FSp)s=−kΔs−q(Δs)^3
work done = Force x displacement

limits are x = 0 to x = 0.15 m
work done

![W = [\dfrac{kx^2}{2}+\dfrac{qx^4}{4}+ C]_0^0.15](https://tex.z-dn.net/?f=W%20%3D%20%5B%5Cdfrac%7Bkx%5E2%7D%7B2%7D%2B%5Cdfrac%7Bqx%5E4%7D%7B4%7D%2B%20C%5D_0%5E0.15)

W = 3.375 + 0.1139
W = 3.3488 J

The ultimate source of electromagnetic waves are the radio sets. The answer is letter C. <span>One example of an
electromagnetic radiation is the visible light. And visible light can be radio
waves, infrared light and X - rays. The rays of the sun are a form of visible
light. It has an electromagnetic radiation of UV (ultra violet) rays. That is
why the radiation at day is greater than at day due to sun’s rays.</span>
The answer is #3: Oxidation because oxidation is when a substance reacts with oxygen, which causes the substance to rust. When a rock contains iron and that iron comes in contact with oxygen, iron oxide is created; this weakens the rock.
<span>4)Increase the mass of both object A and object B.
