3055. 5 kg*m/s2 you do (873kg)(3. 5m/s2)

Answer:

3055.5 N

Explanation:

a = 3.5 m/s^2, m = 873 kg

According to the Newton's second law of motion, force acting on a body is the product of mass of body and the acceleration of body.

F = m x a = 873 x 3.5 = 3055.5 N

A sound source emits 20.0 W of acoustical power spread equally in all directions. The threshold of hearing is 1.0 × 10-12 W/m2.
ahrayia [7]

Answer:

0.0018 W/m²

Explanation:

Power and intensity are related as:

I=\frac{P}{4\pi r^2}

P=  20.0 W (given)

r = 30.0 m (given)

I=\frac{20.0}{4\pi(30.0)^2}=0.0018 W/m^2

Intensity in decibels:

I(dB)=10log\frac{I}{I_o}\\=10log\frac{0.0018}{10^{-12}}=92.5 dB
