Answer:
the noise level of 5400 flies is equal to 84.32 dB
Explanation:
Noise made by house flies = 47 dB from the distance of 2.4 m
to calculate the noise of 5400 flies at a distance of 2.4 m.
the intensity of noise

now, I' = 5400 I₀
= 
=
= 10 ( 3.732 + 4.7 )
= 84.32 dB
hence, the noise level of 5400 flies is equal to 84.32 dB
Answer:
Her angular velocity when tucked is greater than when straight by a factor of 0.23
Explanation:
Moment of inertia (I) = mr^2 = mv^2/w^2
m is mass of the diver
v is diver's linear velocity
w is her angular velocity
When straight, I = 14 kg.m^2
mv^2/w^2 = 14
w^2 = mv^2/14
w = sqrt(mv^2/14) = 0.27sqrt(mv^2)
When tucked, I = 4 kg.m^2
w^2 = mv^2/4
w = sqrt(mv^2/4) = 0.5sqrt(mv^2)
Her angular velocity when tucked is greater than when straight by 0.23 (0.5 - 0.27 = 0.23)
