Answer 2

Explanation:

Hello there!!

I'm a class 11 passout student and I just cleared my boards of class 10th in 2019 with 93% in science.

Sources of energy is a minor chapter for exams and either a question of 3 marks or 5 marks or both can come in exams (as far as I can remember).

You should be cleared with the basic concepts of the chapter and have some ideas on each topic, like what causes pollution and how they can be prevented, the diagrams of the chapter and that Silicon battery is very important along with that dam, where we obtain energy from water. You can also go to Google and type "Sources of energy notes for class 10" and go through it.

Believe me, I too did the same, without going through the entire chapter

Hope my answer helps.......
