Answer:
electrical power is converted by the speaker into sound power 17.25 %
Explanation:
given data
radius = 0.1158 m
power needed = 27.0 W
average sound intensity = 25.6 W/m²
solution
we know sound intensity that is
I = 
...................1
power = intensity × area
Power = 25.6 × 4 ×π×r²
Power = 25.6 × 4 ×π×0.1158²
power = 4.313 W
so here electric power % into sound power
= 
× 100
= 17.25 %

Answer:
Time taken by birdie’s trip = 1.2235 s (Approx)
Explanation:
Given:
Velocity = 4.25 m/s
Displacement = 5.2 m
Find:
Time taken by birdie’s trip = ?
Computation:
⇒ Time taken = Displacement / Velocity
⇒ Time taken by birdie’s trip = Displacement / Velocity
⇒ Time taken by birdie’s trip = 5.2 m / 4.25 m/s
⇒ Time taken by birdie’s trip = 1.2235 s (Approx)
