Hope this helps!
(a brainliest would be appreciated)
Answer:
Sound intensity is the amount of energy carried by sound versus loudness is a subjective measurement of the audible sound.
Sound intensity is measured in watt per square meter where loudness is measured in sones (sone is a subjective measurement and not an SI unit)
The change needed is from 8 to 28, a change of 20 m/s. At a rate of 2m/s/s it will take 10 seconds for it to happen (2x10=20). I hope this helps.
Answer:
The correct answer is D. s₂=4s₁
Explanation:
The distance of a particle is given by:

where
s₀ is the initial position when t=0
v₀ is the initial speed when t=0
a is the constant acceleration
t is the time in seconds
Then, the position s₁ is given by:

As the particle starts from rest v₀=0 and we consider s₀=0, s₁ will be:

Furthermore, the position s₂ is:

In this case t₁=10 s and t₂=20 s (10 seconds later). In other words t₂=2t₁.
We replace the value of t₂ in the second equation (s₂):

Finally, we divide s₂ by s₁ to get the ratio:
