360822 A ball is moving in a direction opposite to the direction of the wind. The ball moves in a upward path as

360823 An aircraft has a mass \(4 \times {10^5}\;kg\) with total wing area \(500\;{m^2}\) flying at a speed of \(720\;\,km/h\). The density of air at its height is \(1.2\;\,kg/{m^3}\). Estimate the dfractional increase in air speed on the upper surface of its wings relative to lower surface

360824 Assertion :
A spinning cricket ball deviates from its trajectory as it moves through air.
Reason :
The ball is moving forward, and relative to it, the air is moving backward.

360825 Air of density \(1.2\,kg{m^{ - 3}}\) is blowing across the horizontal wings of an aeroplane in such away that its speeds above and below the wings are \(150\;m{s^{ - 1}}\) and \(100\;m{s^{ - 1}}\), respectively. The pressure difference between the upper and lower sides of the wings, is:
