On an open ground, a motorist follows a track that turns to his left by an angle of 60° after every 500 m. Starting from a given turn, the displacement of the motorist at the third turn is

A person moves 30 m north, then 30 m east, then 30√2​ m  south-west. His displacement from the original position is:

The (x, y, z) coordinates of two points A and B are given respectively as (0, 4, -2) and (-2, 8, -4). The displacement vector from A to B is:

A bird flies from (-3m, 4m, -3m) to (7m, -2m, -3m) in the xyz- coordinates. The bird's displacement vector is given by

What is the dimensional formula for the universal gravitational constant

Four girls skating on circular ice ground of radius 200 m start from a point P on the edge of the ground and reach a point Q diametrically opposite to P following different paths as shown in figure. For which girl displacement is equal to the actual length of path?

A particle starts moving from point (2, 10, 1). Displacement for the particle is The final coordinates of the particle is

Planck's constant has the same unit as:
