Answer: Option (C) is the correct answer.
Explanation:
Minerals are inorganic substances which have certain characteristic shape or structure along with homogeneous chemical composition.
It is not necessary that a mineral should be formed under the ground.
Substances which have carbon atoms in their structure are called organic compounds. The structure of wood has carbon atoms attached thus, wood is an organic compound.
Therefore, we can conclude that common salt is a mineral because it has a definite crystal structure but wood is not a mineral because it is organic.

Initial Velocity is the velocity at time interval t = 0 and it is represented by u. It is the velocity at which the motion starts. They are four initial velocity formulas: (1) If time, acceleration and final velocity are provided, the initial velocity is articulated as. u = v – at.
Answer:
Same
Explanation:
Let R be the resistance of the cell and E be the emf.
Let i be the current in the circuit.
i = E / R ..... (1)
Now emf and resistance be doubled.
so, i' = 2E/2R = E/R
So, i' = i (From equation (1)
Current remains same.
