The
correct answer to this would be letter:
A. Earth’s volcanoes
Together with weathering and plate tectonic movements, Earth’s
volcanic eruptions and emission of lava has destroyed/covered many of the craters which
were created on Earth during the Period of Heavy Bombardment.
In energy point of view, the larger stone had more potential energy before dropping. impacting the water, the larger one, having more kinetic energy which changed from potential energy, tranfered energy to the water and formed wave. the amplitude of the wave indicate the energy of the wave. more energy more amplitude.
Answer:
<em> The intensity would be 0.01432 W/</em>
<em></em>
Explanation:
The sound intensity is the power that is transmitted by a sound wave per unit area.
Given that
Power output P of the 75-piece orchestra = 72.0 W
The listener's distance r = 20.0 m
The intensity of sound waves (I) can be obtained with the expression below;
I = P/A .............. 1
where P is the power
A is the area, in this case, at the distance r the sound is radiated through a sphere.
A = area of a sphere = 4π
putting it into equation 1, the intensity would be;
I = P/ 4π
Substituting our values we have;
I = 72.0 W / 4 π 
I = 0.01432 W/
Therefore the intensity would be 0.01432 W/
