Quartzite is produced when grains of quartz in sandstone are welded together when the rock is subjected to high temperatures. Quartzite or Quarzit is a hard, non-foliated metamorphic rock which was originally pure quartz sandstone. It is formed when a quartz-rich sandstone is altered by the heat, pressure,

A very loud train whistle has an acoustic power output of 100 W. If the sound energy spreads out spherically, what is the intens

valentina_108 [34]

Answer

given,

Power output of loud train = 100 W

Distance of intensity level from train= 100 m

I₀ = 10⁻¹² W/m²

Intensity of sound = ?

we know,

$I = \dfrac{P}{Area}$

$I = \dfrac{P}{4\pi r^2}$

$I = \dfrac{100}{4\pi 100^2}$

$I =7.957\times 10^{-4}\ W/m^2$

Intensity level

= $10 log(\dfrac{I}{I_0})$

= $10 log(\dfrac{7.975\times 10^{-4}}{10^{-12}})$

= $10 \times 8.900$

= 89 dB
