Answer:
Explanation:
Kinetic energy of a gas molecule = 3/2 k T
1/2 m v² = 3/2 k T
v² ∝ T
(v₁ / v₂)² = T₁ / T₂
( 180 / 48.4 )² = 270 / T₂
13.83 = 270 / T₂
T₂ = 19.52 K .
Exit temp = 19.52 K .

Great question !
The rate at which an object covers distance, without worrying
about the direction it's moving, is the object's SPEED .
When the direction is also given, then you have the object's VELOCITY.
This question is important. It gives us a chance to point out that
"velocity" is not just a fancy word for speed that you use when you
want to sound smart. There's actually an important difference between
'speed' and 'velocity'.
Answer:
The angular velocity is
Explanation:
Generally the acceleration experienced by the propeller blade's is broken down into
The Radial acceleration which is mathematically represented as
And the Tangential acceleration which is mathematically represented as
The net acceleration is evaluated as
Now since angular speed varies directly with angular acceleration so when acceleration is maximum the angular velocity is maximum also and this point if the propeller blade's tip exceeds it the blade would fracture
So at maximum angular acceleration we a have
