Explanation:
The viscosity of water is the thickness of water (it might also be considered the stickiness when talking about other fluids). Water has many properties, and the viscosity of water influences in many of them. We can take the surface tension of a liquid as an example. The more viscous a substance is, higher will the surface tension be and vice versa since there will be a higher and lower attraction between molecules respectively.
→ The surface tension of water is something really important since it contributes in many ways to the environment and if you think about it, if the water was a little less viscous, there wouldn't be water since the viscosity of water makes it resistant to evaporation to a certain degree.

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.
