Answer ) Sound level equation
The intensity of a sound wave is related to its amplitude squared by the following relationship: I=(Δp)22ρvw I = ( Δ p ) 2 2 ρ v w . Here Δp is the pressure variation or pressure amplitude (half the difference between the maximum and minimum pressure in the sound wave) in units of pascals (Pa) or N/m2.
2.5 kg because you cant change the weight of the rock
I think it 32, but i’m not sure
Same as the other person most likely would be 20 times louder as your answer
According to the research, the correct option is c. Protons and neutrons are subatomic particles can be located within the nucleus of an atom.
<h3>What is an atom?</h3>
It is the minimum unit of a substance, which makes up all common matter and is made up of a nucleus with protons and neutrons and several orbital electrons, the number of which varies according to the chemical element.
In this sense, protons are subatomic particles that have a positive energetic charge, while neutrons have no charge.
Therefore, we can conclude that according to the research, the correct option is c. Protons and neutrons are subatomic particles can be located within the nucleus of an atom.
