148932 Water falls from a $40 \mathrm{~m}$ high dam at the rate of $9 \times 10^{4} \mathrm{~kg}$ per hour. Fifty percent of gravitational potential energy can be converted into electrical energy. Using this hydroelectric energy number of $100 \mathrm{~W}$ lamps, that can be lit, is:
(Take $\mathrm{g}=10 \mathrm{~ms}^{-2}$ )

148933 Position of a $3 \mathrm{~kg}$ mass moving along the $x$-axis is given by $x=0.3 \cos (\omega t) \mathrm{m}$. If $K(t)$ denotes the kinetic energy at time $t$,
Then the value of $\frac{K\left(\frac{\pi}{6 \omega}\right)}{K\left(\frac{\pi}{3 \omega}\right)}$ is
