The answer is A. You should Read the book twice again. But even then also you think that the answer is B than the book is a spam. Adaptation is the permanent feature of an organism which helps it to survive in its habitat, while acclimatisation is a temprory feature or change in feature of an organism which helps it to survive in any other place rather than its habitat......................................................................

Kailash gopal from D.A.V Boys Senior secondary school, Gopalapuram, Chennai
Subject :NSO    Class : Class 8

Read the given statements and select the correct option.
Statement 1 : While drawing a line on a paper, friction force acts on paper in the same direction along which line is drawn on the paper.
Statement 2 : Friction always opposes motion.

A Both statements 1 and 2 are true and statement 2 is the correct explanation of statement 1.
B Both statements 1 and 2 are true but statement 2 is not the correct explanation of statement 1.
C Statement 1 is true and statement 2 is false.
D Both statements 1 and 2 are false.


I don't understand how statement 1 is true

Ans 1:

Anshuman D from MVM, Hyderabad
Class : Class 8
It should be E first statement is incorrect while second statement is correct.

Ans 2:

Ananya Gupta from DPS EAST, BANGALORE , Bengaluru
Class : Class 5
statement 1 is falsewhereas statement 2 should be true

Ans 3:

Yash Bindal from Global Indian International School, Singapore
Class : Class 9
Friction always opposes motion but while drawing a line on a paper, the frictional force acts in the opposite direction in which the tip of the pen acts / the line is drawn. I think all options are incorrect as 'statement 1' is wrong but 'statement 2' is right

Ans 4:

saumil from Prudence, Delhi
Class : Class 5
In my opinion statement 2 is true and statement 1 is false as friction always opposes the motion of an object. Also the friction between the pencil and paper should be exerted in the opposite direction.

Ans 5:

Ankit kumar Jha from Ryan International School, Ghaziabad
Class : Class 8
YES THERE IS A LOT OF ERROR IN THE OPTIONS

Ans 6:

saumil from Prudence, Delhi
Class : Class 5

Ans 7:

Vidush from Dav pakhowal Ludhiana, Ludhiana
Class : Class 9
No statement 1 is correct where as statement 2 is also correct

Ans 8:

ANUBHA MAHAJAN from LOTUS VALLEY INTERNATIONAL SCHOOL, NOIDA
Class : Class 10
not in all cases friction opposes, this is proved from statement 1 as friction acts backward on the paper and it will act forward on the direction where the pencil is moved

Ans 9:

Shlok Ghadekar from Tomoae school, Amravati
Class : Class 8
All the options must be incorrect as friction always opposes motion and friction acts in direction opposite of force applied but there is no option saying this

Ans 10:

Amazing Kids from DPS Panipat Refinery, Panipat
Class : Class 8
Yes , I also agree that friction always opposes motion and the following options are incorrect as *Statement 1* is incorrect and *Statement 2* is correct. There is surely some error.

Ans 11:

Ethel shiju from National Public School Indiranagar, Bangalore
Class : Class 9
But friction always opposes motion...then how are they saying that option c is true?
