AIPMT 2015 | Properties of Matter Question 42 | Physics

The cylindrical tube of a spray pump has radius R, one end of which has n fine holes, each of radius r. If the speed of the liquid in the tube is V, the speed of the ejection of the liquid through the holes is

$${{VR{}^2} \over {{n^3}{r^2}}}$$

$${{{V^2}R} \over {nr}}$$

$${{V{R^2}} \over {{n^2}{r^2}}}$$

$${{V{R^2}} \over {n{r^2}}}$$

On observing light from three different starts P, Q and R, it was found that intensity of violet colour is maximum in the spectrum of P, the intensity of green colour is maximum in the spectrum of R and the intensity of red colour is maximum in the spectrum of Q. If T_P, T_Q and T_R are the respective absolute temperatures of P, Q and R, then it can be conclued from the above observations that

T_P < T_R < T_Q

T_P < T_Q < T_R

T_P > T_Q > T_R

T_P > T_R > T_Q
