Nylon does not have the smell of burning hair. So the answer should be d.

Ans 2:

Class : Class 8
Nylon should neither have a smell of burning hair nor the smell of burning paper. Nylon has a celery or plastic-like cell. Hence the correct answer is D. But on the other hand when acrylic burns, it shrinks and converts into black beads. On this contrast, the correct answer will be B with respect to acrylic and D with respect to Nylon. There is definitely an error in the options of the answers!

It should be option A- Only 1 As water is liquid, the only change that can be seen is that of the change in shape. it volume will remain the same

Ans 2:

Class : Class 9
A

Ans 3:

Class : Class 9
The answer must be the option "A", as it states so "Farheen filled container X with 100 ml of water." Container Y had just a different shape, and it was also broader, so how can it be the option "C"?

Ans 4:

Class : Class 5
the correct answer is d

Ans 5:

Class : Class 4

Ans 6:

Class : Class 8
Actually D is correct but there is a typing mistake in D4th Tuesday of November 20XX = 28 November. The next day is 29 November. So D is correct not A. There is a typing mistake in D, but that does not mean D is wrong.

Ans 7:

Class : Class 5

Ans 8:

Class : Class 5
sof please tell that what is novemberook

Ans 9:

Class : Class 8
[d] is wrong

Ans 10:

Class : Class 7
Novemberook is a typing mistake. Everyone can see that.

Ans 11:

Class : Class 9
The answer is D because they are saying AFTER 4th Tuesday of November 20XX that means 4th Tuesday is 28th November but after 28th November the date is 29th November .

Ans 12:

Class : Class 4
They're saying after 4th tuesday that means 29 November. Novemberook could be a mistake.

Ans 13:

Class : Class 7
Novemberbook is a typing error. So the ans is D because it is telling 4th Tuesday which is 28th and it is said that just after 28th so the ans is D

Ans 14:

Class : Class 4
Novemberook ain't nothin. there is nothin' called like that but is the ans.
