A jet plane flies in the air because

Select the correct reason for the uplift of a jet plane A jet plane moves up in air because

A jet plane flies through air with a velocity of 2 Mach. While the velocity of sound is 332 mis, the air speed of the plane is

The proposal to ban supersonic jet planes in Russia is because (A) They travel with very high speed (B) It is dangerous to travel in them (C) Their exhaust gases react with ozone

Flying of rockets and jet planes is explained on the basis of

The angle of elevation of a jet plane from a point A on the ground is 60^(@) . After a flight of 15 seconds, the angle of elevation changes to 30^(@) . If the jet plane is flying at a constant height of 1500 sqrt(3) meter, find the speed of the jet plane. (sqrt(3) - 1.732)

The angle of elevation of a jet plane from a point P on the ground is 60°.After a flight of 15 second the angle of elevation changes to 30°. If the jet plane is flying at a constant height of 1500sqrt3 ,find the speed of the jet plane in km/ hr.

The angle of elevation of a jet plane from a point on the ground had measure 60^(@) . After a flight of 30 seconds, the angle of elevation has measure 30^(@) . If the jet plane is flying at a constant height of 4500 sqrt3m , find the speed of the jet plane

The angle of elevation of a jet plane from a point A on the ground is 60^@ . After a flight of 30 seconds, the angle of elevation changes to 30^@ . If the jet plane is flying at a constant height of 3600sqrt(3)m , find the speed of the jet plane.
