Master Jiang, I'm cracked (third update) _1

This student who had handed in his paper early and was the last to take the exam had filled in all the blanks on his answer sheet.

It was said that this joint examination of ten schools was unprecedentedly difficult. Looking at the full of answers and clear analysis steps, especially the three big questions in physics, if one didn't understand these questions, they could only write two formulas at most.

This student 'Meng Fu' had not only written down the steps in detail, but he had also come up with the final answer.

They didn't know if the answer was correct, but looking at the clear steps, it didn't look like it was written randomly.

Could it be that the rumors were wrong this time and the contents of the exam were not difficult?
