marta [7]3 years ago
7 0

Answer:

2/3.or 0,67

Explanation:

acceleration = Result or sum of force / the mass

a = F/m

a = (35-25)/15

a = 10/15 = 2/3 m/s²

a = 0,67 m/s²

Quadrupling the power output from a speaker emitting a single frequency will result in what increase in loudness (in units of dB
Leviafan [203]

Answer:

<em>6.02 dB increase  </em>

<em></em>

Explanation:

Let us take the initial power from the speaker P' = P Watt

then, the final power P = 4P Watt

for a given unit area, initial intensity (power per unit area) will be

I' = P Watt/m^2

and the final quadrupled sound will produce a sound intensity of

I = 4P Watt/m^2

Increase in loudness is gotten from the relation

ΔL =  10log_{10} \frac{I}{I'}

where

I = final sound intensity

I' = initial sound intensity

imputing values of the intensity into the equation, we have

==>  10log_{10} \frac{4P}{P} =  10log_{10} 4 = <em>6.02 dB increase  </em>
