The answer is a) manganese nodules
Answer:
The EMF of the batteries connect in series in the circuit is 12 V.
Explanation:
Given;
two batteries, each is 6 V
The EMF of the batteries connect in series in the circuit is calculated as sum of the voltage of the two batteries since they are connected in series.
EMF = V₁ + V₂
EMF = 6V + 6V
EMF = 12 V
Therefore, the EMF of the batteries connect in series in the circuit is 12 V.
