The slope of graph as shown in figure at points $1,2$ and $3$ is $m_1, m_2$ and $m_3$ respectively then
$m_1 > m_2 > m_3$
$m _1 < m _2 < m _3$
$m_1=m_2=m_3$
$m _1= m _3 > m _2$
If $F = \frac{2}{{\sin \,\theta + \sqrt 3 \,\cos \,\theta }}$, then minimum value of $F$ is
Magnitude of slope of the shown graph.
The coordinates of a particle moving in $XY$-plane vary with time as $x=4 t ^2 ; y=2 t$. The locus of the particle is a :-
Frequency $f$ of a simple pendulum depends on its length $\ell$ and acceleration $g$ due to gravity according to the following equation $f=\frac{1}{2 \pi} \sqrt{\frac{ g }{\ell}}$. Graph between which of the following quantities is a straight line?
