Surveys which are carried out to depict mountains rivers water bodies wooded areas and other cultural details are known as

The motion of a particle making in a straight line is given by 

s = t3 – 3t2 + 2t + 5
Then the extreme velocity is

A pilot flying his bomber at a height of 1962 m with a uniform velocity of 720 kmph wants to
strike a target. He should release the bomb ______ distance before reaching that target

If a projectile is fired at angle a with initial velocity u, it traces the

A projectile is fired with initial velocity u at an angle 55° to horizontal. Then second projectile
was fired with the same velocity but at an angle 35° to horizontal. Then the ratio of horizontal
projection of first one to second one is

If air resistance is to be considered, to get maximum range the angle of projection should be

A projectile was fired with initial velocity u an angle a to horizontal on an inclined plane making angle b to horizontal, range is maximum when

A river is flowing at a velocity of 5 kmph. A motor boat can move at a velocity of 10 kmph with
uniform velocity. To reach the other bank in minimum time the boat should be set at q = … to the
direction of flow

The system of forces acting on a moving body is in a dynamic equilibrium with the inertia force of the body. This low is known as

A man of weight W moves up in a lift. The pressure applied by him on the lift when acceleration is a is,
