An aeroplane is flying horizontally at a height of `2/3k m` with a velocity of 15 km/h. Find the rate at which it is receding from a fixed point on the ground which it passed over 2 min ago.

An aeroplane is flying horizontally at a height (2)/(3) km above the ground with a velocity of 15km/h. find the rate at which it is receding from a fixed point on the ground which it passed over 2 minutes ago.

An aeroplane is flying horizontally from west to east with a velocity of 900 km/h. Calculate the potential difference developed between the ends of its wings having a span of 20 m. The horizontal component of the Earth's magnetic field is 5xx10^(-4)T and the angle of dip is 30^(@) .

A plane is flying horizontally at a height of 1960 m at 600 km*h^(-1) with respect to the ground . On reaching a point directly above A , the plane drops an object which reaches the ground at B. Find the distance AB.

An aeroplane is flying with a velocity of 216 km/h at an altitude of 1960 m relative to the ground. It drops a bomb when it is just above a point A on the ground . The bomb hits the ground at B. The distance AB is

The distance between the extremities of the two wings of an aeroplane is 30m. It is flying horizontally with a velocity of 1080km .h^(-1) . The vertical component of earth's magnetic field in that region is 4.5xx10^(-5)T . Find the emf induced across the extremities of the two wings.

A body is projected horizontally from the top of a building of height h. Velocity of projection is u. Find the time it will take to reach the ground ,
