Answer:
The decrease in decibels is 0.1 dB.
Explanation:
Let the intensity of one chorus is Io.
let the intensity of 1000 vocalist is dB.
The intensity of 1000 vocalist is 1000 Io.
..... (1)
let the intensity of 999 vocalist is dB'.
..... (2)
So, the change is
= dB - dB' = 30 - 29.9 = 0.1 dB
Short-term regulation of blood pressure is controlled by the autonomic nervous system . Changes in blood pressure are detected by baroreceptors. These are located in the arch of the aorta and the carotid sinus. Increased arterial pressure stretches the wall of the blood vessel, triggering the baroreceptors.

Answer:
c. 43 m/s
Explanation:
Given the following data;
Displacement, S = 90 meters
Time, t = 5.55 seconds
To find the initial velocity;
We would use the second equation of motion given by the formula;
Where;
- S represents the displacement or height measured in meters.
- u represents the initial velocity measured in meters per seconds.
- t represents the time measured in seconds.
- a represents acceleration measured in meters per seconds square.
We know that acceleration due to gravity is -9.8m/s² because the direction is downward.
Substituting into the equation, we have;
Rearranging the equation, we have;
Initial velocity, u = 43.41 ≈ 41 m/s
