Warmer air has molecules more spread out, so I'd say a decrease in air pressure.
Glottis I believe is the answer.
Answer:
First Condition of Equilibrium is that it must be experiencing no acceleration or the external forces acting on the body should be zero.
Diameter = 0.170 meter
Circumference = 0.170 π meters
530 rpm = 530 circumferences / minute
= (530 x 0.170 π meters) / minute
= 283.06 meter.minute
= 4.72 meters/second
Acceleration = force / mass.
A = 100/50 = 2 m/s^2 .
