A body is projected horizontally with a velocity $u$ from a height $h$. If $R$ is the horizontal range and $T$ is the time of flight, which of the following is correct (neglecting air resistance)?

A particle moves along a trajectory defined by $x = t^3 - 6t^2 + 9t + 2$ and $y = t^2 - 2t + 1$, where $x$ and $y$ are in meters and $t$ is in seconds. What is the magnitude of the displacement of the particle between $t=0$ and $t=4$ seconds?

A bee flies in a spiral path described by $r = 2t$ and $heta = \pi t$, where $r$ is in meters, $heta$ is in radians, and $t$ is in seconds. What is the magnitude of the bee's displacement from $t = 0$ to $t = 2$ s?

A particle's position vector is given by $\vec{r}(t) = (3t^2 - 2t)\hat{i} + (t^3 - 4)\hat{j}$. At what time $t$ is the particle's displacement from the origin equal to 5 units?

A body travels along a path described by $y = x^2$. What is the ratio of distance to displacement when moving from $(0,0)$ to $(2,4)$?

A particle moves in a circular path of radius R. It completes one and a half revolutions. What is the ratio of the distance traveled to its displacement?

An ant crawls along the edges of a cube of side length 'a'. It starts at one corner and reaches the diagonally opposite corner. If the ant only crawls along the edges and takes the shortest possible path, what is the ratio of the distance it crawls to its displacement?

The dimensional formula for the gravitational constant G multiplied by the permittivity of free space $\epsilon_0$ is:

If the speed of light $c$, Planck's constant $h$ and gravitational constant $G$ are chosen as fundamental units, then the dimensions of time in terms of these units are:

The dimensional formula of permeability of free space $\mu_0$ is given by:
