The operation of a nuclear reactor is said to be critical when the value of the neutron multiplication factor $K$ is:

The square root of $134 + \sqrt{6292}$ is:

$(b \times c) \times (c \times a) = $

$A$ mass of $2.9 \ kg$ is suspended from a string of length $50 \ cm$ and is at rest. Another body of mass $100 \ g$,which is moving horizontally with a velocity of $150 \ m/s$,strikes and sticks to it. Subsequently,when the string makes an angle of $60^{\circ}$ with the vertical,the tension in the string is $(g=10 \ m/s^2)$. (in $N$)
