The reverberation time with 800 audiences is 0.875 seconds.
<h3>
Reverberation time with 800 audience</h3>
R₁V₁ = R₂V₂
where;
- R₁ is the reverberation time with 400 audience
- R₂ is the reverberation time with 800 audience
- V₁ is initial volume
- V₂ is final volume
R₂ = R₁V₁/V₂
R₂ = (1.4 x 500) / 800
R₂ = 0.875 seconds
Thus, the reverberation time with 800 audiences is 0.875 seconds.

Answer:
The coefficient of static friction between the car and the track
u=0.572
Explanation:
We don't know the mass of the car or any other information so the acceleration is the reason to solve the friction coefficient
∑
As we know

Also the center ward direction forces



But now vt relation with the tangential acceleration

replacing


So magnitude of the force can get by

Get the factor to simplify


Solve to u'


any two uses of good conductor of heat are
aluminium, cooper, metal are good conductor of heat and they are used for making utensils.
gold, silver, are also good conductor of heat they are used for making jewelleries.
