A fully loaded Boeing aircraft has a mass of 3.3xx10^(5) kg . Its total wing area is 500 m^(2) . It is in level flight with a speed of 960 km//h . (a) Estimate the pressure difference between the lower and upper surfaces of the wings (b) Estimate the fracitional increases in the speed of the air on the upper surfaces of the wing relative to the lower surface. The density of air is 1.2 kg//m^(3) .

An aeroplane of mass 3xx10^(4)kg and total wing area of 120 m^(2) is in a level flight at some height the difference in pressure between the upper and lower surfaces of its wings in kilo pascal is (g=10m//s^(2))

An aircraft of mass 4 xx 10^(5)kg with total wing area 500m^(2) in level flight at a speed of 720 km h^(-1) . The density of a at its height is 1.2 kgm^(-3) . The fractional increases in the speed of the air on the upper surface of its wings relative to the lower surface is (take g = 10 ms^(-2) )

The rest mass of a proton is 1.67xx10^(-27) kg Its total energy when it moves with a speed of 2.1 xx10^(8) m/s is

Air of density 1.2kg m ^(-3) is blowing across the horizontal wings of an aeroplane in such a way that its speeds above and below the wings are 150 ms^(-1) and 100 ms ^(-1), respectively. The pressure difference between the upper and lower sides of the wings, is :

An aeroplane having a wing space of 35m flies due north with the speed of 90ms^(-1) given B=4xx10^(-5)T . The potential difference between the tips of the wings will be

A plane is in level flight at constant speed and each of its two wings has an area of 25 m^2 . If the speed of the air is 180 km / h over the lower wing and 234 km / h over the upper wing surface, determine the plane's mass. Take air density to be 1 kg m^-3 and g = 9.81 ms^-2 .

A plane is in level flight at constant speed and each of its two wings has an area of 20m^(2). If the speed of rthe air is 180 km/h over the lower wing and 216 km/h over the upper wing surface, determine the plane's mass. (Take air density to be 1 kg m ^(-3) and g= 10m//s ^(2)).
