Answer:
The magnitude of the centripetal acceleration during the turn is
Explanation:
Given :
Speed to the airplane in circular path , v = 115 m/s.
Time taken by plane to turn , t= 15 s.
Also , the plane turns from east to south i.e. quarter of a circle .
Therefore, time taken to complete whole circle is ,
Now , Velocity ,
Also , we know :
Centripetal acceleration ,
Putting all values we get :
Hence , this is the required solution .
Answer:
1.23917 m
0.14323 s
Explanation:
v = Speed of sound in dry air at 20 °C = 343.5 m/s
f = Frequency of note C# = 277.2 /s = 277.2 Hz
λ = Wavelength
Wavelength = 1.23917 m
Distance the wave needs to travel is 49.2 m
Time = Distance / Speed
Time taken for the sound to travel across the concert hall is 0.14323 s
