A particle moves along a straight line $OX$. At a time $t$ (in second) the distance $x$ (in metre) of the particle from $O$ is given by $ x=40+12t-t^{3} $ How long would the particle travel before coming to rest?
Interference was observed in an interference chamber when air was present. Now, the chamber is evacuated and if the same light is used, a careful observation will show
