Answer:
Acceleration is 9.8 m/s^2
Explanation:
If the boulder falls from the cliff then the gravitational force will apply on it and due to gravitational force, the acceleration will be generated. Moreover, the acceleration generated in this case will be called the acceleration due to gravity. Therefore, the acceleration will remain constant irrespective of time and height because the gravitational force is constant. Thus, acceleration is 9.8 meters per second square.
Answer:
The sound intensity of source #2 is 38.3 W/m²
Explanation:
Given;
sound intensity of source #1, I₁ = 38.3 W/m²
sound intensity of source #2, I₂ = 2.6 dB greater than 38.3 W/m²
To determine he sound intensity of source #2 in W/m², we must convert 2.6 dB to sound intensity in W/m².
Thus, sound intensity of source #2 = 38.3 W/m² + 1.8197 x 10⁻¹² W/m² = 38.3 W/m²
Therefore, the sound intensity of source #2 is 38.3 W/m²
