Answer:
80 dB
Explanation:
Sound intensity is inversely proportional to the square of the distance traveled by the sound.
Thus;
r1^2 divide by r2^2 = L2divideL1
where r= distance (m)
L= sound intensity (decibal dB)
8squared divide by 4 squared = L2 divide 20 dB
L2 = 4 × 20
L2= 80 dB
This means that the sound is increased from 20 dB to 80 dB.
The Reactant would be carbon Dioxide wouldn't it? Because isn't that what goes into Photosynthesis, and oxogen and glucose is the outcome (thankfully!!)
Hoped this helps someone :)))))
