The part of the fallopian tube closest to the ovary is:

$A$ uniform rod $AB$ of mass $m$ and length $l$ is at rest on a smooth horizontal surface. An impulse $P$ is applied to the end $B$. The time taken by the rod to turn through a right angle is

If $A=\left[\begin{array}{rr}i & -i \\ -i & i\end{array}\right]$ and $B=\left[\begin{array}{rr}1 & -1 \\ -1 & 1\end{array}\right]$,then find $A^8$. (in $B$)

The machine gun fires $240$ bullets per minute. If the mass of each bullet is $10 ~g$ and the velocity of the bullets is $600 ~ms^{-1}$,the power (in $kW$) of the gun is
