In an electroplating experiment,$m \ g$ of silver is deposited when $4 \ A$ of current flows for $2 \ min$. The amount (in $g$) of silver deposited by $6 \ A$ of current flowing for $40 \ s$ will be:

The rate of growth of bacteria in a culture is proportional to the number of bacteria present and the bacteria count is $1000$ at $t = 0$. The number of bacteria is increased by $20 \%$ in $2 \text{ hours}$. If the population of bacteria is $2000$ after $\frac{k}{\log \left(\frac{6}{5}\right)} \text{ hours}$,then $\left(\frac{k}{\log 2}\right)^2$ is
