A carnot engine working between `400K` and `800K` has a work output of `1200 J` per cycle . What is the amount of heat energy supplied to the engine from source per cycle?

Explanation

To find the amount of heat energy supplied to the Carnot engine from the source per cycle, we can use the concept of efficiency of the Carnot engine. The efficiency (η) of a Carnot engine is given by the formula:

\[ \eta = 1 - \frac{T_2}{T_1} \]

where:
- \(T_1\) is the temperature of the hot reservoir (source) in Kelvin,
