Solve the all parts of following problem given below:
Problem: One rechargeable battery of mass 15.0 g delivers an average current of 18.0 mA to a compact disc player at 1.60 V for 2.40 h before the battery needs to be recharged. The recharger maintains a potential difference of 2.36 V across the battery and delivers a charging current of 13.5 mA for 4.20 h.
Part A: What is the efficiency of the battery as an energy storage device?
Part B: How much internal energy is produced in the battery during one charge-discharge cycle?
Part C: If the battery is surrounded by ideal thermal insulation and has an overall effective specific heat of 975 J/kg°C, by how much will its temperature increase during the cycle?
