Here are the solutions to your questions:

Chemistry
What is the use of Mg in a Leclanché cell?
The Leclanché cell typically uses a zinc anode, a carbon cathode, and an ammonium chloride electrolyte. Magnesium is not a standard component.
The final answer is $\boxed{\text{d) Not used in the cell}}$

Physics
What is the dimension of momentum?
Momentum ( $p$ ) is defined as mass ( $m$ ) multiplied by velocity ( $v$ ).

p = mv

The dimension of mass is M.
The dimension of velocity is length (L) divided by time (T), which is LT⁻¹.
Therefore, the dimension of momentum is:
