Answer:
Ae/A* = 1.115
Explanation:
Let the reservoir pressure be 
Let the exit pressure be 
Ratio of reservoir pressure and exit pressure
= 3.182
For the above value of pressure ratio
Obtain the area ratio from the isentropic flow table
Ae/A* = 1.115
The value of pressure ratio is Ae/A* = 1.115
False....................................
Answer:
f=4Hz
Explanation:
frequency of a wave if it has a wavelength of 3.0 m and a wave speed of 12m/s
v=fλ → f=v/λ
f=12/3
f=4Hz
