A person in a lift is holding a water jar, which has a small hole at the lower end of its side. When the lift is at rest, the water jet coming out of the hole hits the floor of the lift at a distance d of 1.2 m from the person. In the following, state of the lift’s motion is given in List I and the distance where the water jet hits the floor of the lift is given in List II. Match the statements from List I with those in List II and select the correct answer using the options given below the lists.

List - I	List - II
P. Lift is accelerating vertically up.	1. d=1.2 m
Q. Lift is accelerating vertically down with an acceleration less than the gravitational acceleration.	2. d > 1.02 m
R. Lift is moving vertically up with constant speed.	3. d < 1.2 m
S. Lift is falling freely.	4. No water leaks out of the jar

Parallel rays of light of intensity $$I$$ = 912 Wm^–2 are incident on a spherical black body kept in surroundings of temperature 300 K. Take Stefan-Boltzmann constant $$\sigma $$ = 5.7 $$ \times $$ 10^–8 Wm^–2K^–4 and assume that the energy exchange with the surroundings is only through radiation. The final steady state temperature of the black body is close to
