1. How do latitude and inclination affect the amount of solar power collected. What else can affect the solar power collected?
2. How to calculate the doubling time with exponential growth given a percent growth. Like power plant problem.
3. A Carnot heat engine has water ice as a cold reservoir and has an efficiency of 70%. The cold reservoir then warms to 100 degrees Celsius. What would the efficiency be now if the hot reservoir stayed at the same temperature?
4. What work is and how that changes kinetic energy. (Work-Energy theorem).
