A

Torricelli's theorem

B

Bernoulli's theorem

C

Law of gravitation

D

Continuity equation

Text Solution

Verified by Experts

The correct Answer is:
B
The lifting of an airoplane is based on bernoulli's principle . When airplane moves through air, prssure difference is created due to higher speed of air in the region the wing

A block is released from rest on a smooth inclined plane having inclination 37^(@) with the horizontal. The inclined plane is fixed on a lift which is moving up with retardation 5ms^(-2) . Find out the displacement of the block with respect to the lift in initial 1 second (Take g=10ms^(-2) )

A lift is moving down with acceleration a. A man in the lift drops a ball inside the lift. The acceleration of the ball as observed by the man in the lift and a man standing stationary on the ground are respectively

The flow speeds of air on the lower and upper surfaces of the wing ofan aeroplane are v and sqrt2v respectively. A is the area of the wing and rho is the density of th e surrounding air. What is the force of the dynamic lift on the wing ?

The captain of a plane wishes to proceed due west. The cruising speed of the plane is 245 m/s relative to the air. A weather report indicates that a 38.0 m/s wind is blowing from the south to the north. In what direction, measured with respect to due west, should the pilot head the plane relative to the air?

Air streams horizontally past an air plane. The speed over the top surface is 60 m/s, and that under the bottom surface is 45 m/s. The density of air is 1.293 kg/ m^(3) , then the difference in pressure
