Six moles of an ideal gas perform a cycle shown in the figure. If the temperatures are $T_A = 600\,K, T_B = 800\,K, T_C = 2200\,K$ and $T_D = 1200\,K,$ the work done per cycle is...... $kJ$

An electron beam travels with a velocity of $1.6 \times 10^7 \ m/s$ perpendicularly to a magnetic field of intensity $0.1 \ T$. Calculate the radius of the path of the electron beam. (Given: $m_e = 9 \times 10^{-31} \ kg$,$e = 1.6 \times 10^{-19} \ C$)

$p$ points are chosen on each of the three coplanar lines. The maximum number of triangles formed with vertices at these points is

The image of the line $x+y-2=0$ in the $y$-axis is

Box $A$ contains $2$ black and $3$ red balls, while Box $B$ contains $3$ black and $4$ red balls. Out of these two boxes, one is selected at random; and the probability of choosing Box $A$ is double that of Box $B$. If a red ball is drawn from the selected box, then the probability that it has come from Box $B$ is:

Which of the following concentration factors is affected by a change in temperature?
