Hey, good to see you again. 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 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: [p
