When a certain jet engine is running, 11,500 w of power goes into its deafening roar. how far away from this engine can you stand before the sound level you experience crosses the "threshold of pain," 120 db? assume that the engine generates sound equally in all directions.

30.25129 m

Explanation:

I = Sound intensity

= Intensity level = 120 dB

= Threshold of human hearing =

r = Distance

P = Power = 11500 W

Intensity of sound is given by

Intensity is given by

The distance is 30.25129 m

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.
