Answer:
The sound level of the 26 geese is
Explanation:
From the question we are told that
The sound level is
The number of geese is
Generally the intensity level of sound is mathematically represented as
The intensity of sound level in dB for one goose is mathematically represented as
Where I_o is the threshold level of intensity with value
is the intensity for one goose in
For 26 geese the intensity would be
Then the intensity of 26 geese in dB is
From the law of logarithm we have that
Answer:
h2 = 0.092m
Explanation:
From a balance of energy from point A to point B, we get speed before the collision:
Solving for Vb:
Since the collision is elastic, we now that velocity of bead 1 after the collision is given by:
Now, by doing another balance of energy from the instant after the collision, to the point where bead 1 stops, we get the distance it rises:
Solving for h2:
h2 = 0.092m
