Final answer:
To find the rate of dissipation of electrical energy in the battery, first calculate the potential difference across the terminals using Ohm's Law. Then use the formula P = IV to calculate the rate of thermal energy dissipation.
Step-by-step explanation:
In order to find the rate of dissipation of electrical energy in the battery, we need to first calculate the potential difference across the terminals. This can be done using Ohm's Law, V = IR, where V is the potential difference, I is the current, and R is the resistance. In this case, the current is 60 A and the resistance is the sum of the internal resistance and the resistance of the load connected to the battery. Once we have the potential difference, we can calculate the rate of thermal energy dissipation by using the formula P = IV, where P is the power dissipated, I is the current, and V is the potential difference.
