What is heavy water?

The refluxing of $(CH_3)_2NCOCH_3$ with acid gives:

In a step-up transformer, the turn ratio is $1:2$. A Leclanche cell $(e.m.f. 1.5\,V)$ is connected across the primary. The voltage developed in the secondary would be.......$V$

$CrO_3$ dissolves in aqueous $NaOH$ to give:

If $m_1, m_2, m_3$ and $m_4$ are respectively the magnitudes of the vectors $\overrightarrow{a}_1=2 \hat{i}-\hat{j}+\hat{k}$,$\overrightarrow{a}_2=3 \hat{i}-4 \hat{j}-4 \hat{k}$,$\overrightarrow{a}_3=\hat{i}+\hat{j}-\hat{k}$ and $\overrightarrow{a}_4=-\hat{i}+3 \hat{j}+\hat{k}$,then the correct order of $m_1, m_2, m_3$ and $m_4$ is
