Mountain ranges and belts are built through the process called what

nordsb [41]

They are built through the process of what called as Orogenesis. Orogenesis is the process of the mountain making, upheaval or formation. It is also called Orogeny. Orogeny is the process which the mountains are formed. The process of mountain formation especially when it is faulting. The making of the mountains is also Orogenesis. An orogeny is an event which leads to mountain deformation due to some interaction between Earth Lithosphere and tectonic plates. When continental plates crumple and pushed forward to form one or more mountain ranges an orogen or orogenic belt develops, it involves many geological processes called orogenesis.

A sound from a source has an intensity of 270 dB when it is 1 m from the source.

Rufina [12.5K]

Remember that sound intensity decreases in inverse proportion to the distance squared. So, to solve this we are going to use the inverse square formula: $\frac{I_{2} }{I_{1}}= (\frac{d{2} }{d_{1}})^2$
where
$I_{2}$ is the intensity at distance 2
$I_{1}$ is the intensity at distance 1
$d_{2}$ is distance 2
$d_{1}$ is distance 1

We can infer for our problem that $I_{1}=270$ , $d_{1}=1$ , and $d_{2}=3$ . Lets replace those values in our formula to find $I_{2}$ :
$\frac{I_{2} }{I_{1}}= (\frac{d{2} }{d_{1}})^2$
$\frac{I_{2} }{270} =( \frac{1}{3} )^2$
$\frac{I_{2} }{270} = \frac{1}{9}$
$I_{2}= \frac{270}{9}$
$I_{2}=30$ dB

We can conclude that the intensity of the sound when is <span>3 m from the source is 30 dB.</span>
