(a)
Answer to Problem 47GP
Explanation of Solution
Given:
Intensity,
Diameter of satellite,
Time interval,
Formula used:
The total energy can be given as:
Here, power is given as:
So, the total energy is given by:
Here,
Calculation:
The area can be calculated as follows:
Putting all the values in the above expression, we get:
Conclusion:
Hence, the total energy is
(b)
