Ans 1:

Class : Class 9
The Options Are wrong I guess because only (i),(ii)and(iii) are in use

Ans 2:

Class : Class 8
The Options Are wrong because only 123 are in use.

Ans 3:

Class : Class 8

Ans 4:

Class : Class 8
All the properties friction are in use. Hence, the correct one option 'D'.

Ans 5:

Class : Class 8
The Options Are wrong because only 123 are in use.

Ans 6:

Class : Class 7
The answer is correct, as when friction occurs, obviously, all of its properties will occur, even if not all of the properties are required. That's... how friction works.

Ans 7:

Class : Class 8
It's not asking about which properties occur (which would be all of them), it's asking which are in use. And that's only 1, 2, and 3. So the options are wrong
