1. Thanks a lots sir

2. Thanks sir

3. in question 26th the parrot suts on a bare high power line so why it doesn’t get a shock ?

4. What’s the probability of these questions coming in exam?

1. These questions are based on NCERT, and 1 to 2 questions can be asked in board exams.

5. wire will have a insulating covering which will pevent parrot from schok

6. Plz. Make this available as a PDF.

It will be better to solve these questions as a practice paper..
