Question
Is the time variation of position shown in figure observed in nature possible?

Answer

No, when x increases, the time first increases and then decreases. It is not possible. It implies that at a given time, the body in motion is simultaneously at two different positions which is not possible.

A manometer reads the pressure of a gas in an enclosure as shown in Fig.(a) When a pump removes some of the gas, the manometer reads as in Fig. (b) The liquid used in the manometers is mercury and the atmospheric pressure is $76cm$ of mercury. Give the absolute and gauge pressure of the gas in the enclosure for cases (i) and (ii) in units of cm of mercury. How would the levels change in case (i) if $13.6cm$ of water (immiscible with mercury) are poured into the right limb of the manometer? (Ignore the small change in volume of the gas.)
