Answer:
The equation which describes conservation of charge is 
Explanation:
The law of conservation charge states that for an isolated system that sum of initial charges is equal to sum of final charges, that is the total charge is conserved.
let the sum of initial charges = 
let the sum of the final charges = 

Therefore, the equation which describes conservation of charge is

An object's angular momentum is proportional to its moment of inertia.
Option D
<u>Explanation:</u>
Momentum is the measure of an object's movement with respect to its mass and velocity. So it is determined as the product of mass and velocity. An object moving in linear motion, will experience linear momentum.
Similarly, if an object moves in circular motion, then the momentum will be angular momentum. So it is measured as the product of moment of inertia with angular velocity.

Here L is the angular momentum , I is the moment of inertia and ω is the angular velocity.
Thus, the angular momentum is directly proportional to the moment of inertia.
