Ans 3:

Class : Class 5
On page 75 of "Learning Science for Smarter Life" for class V it is mentioned that person should sit down and lean forward. It also says to pinch the nose.All answer choices of this question are therefore incorrect.

Ans 4:

Class : Class 9
i agree with Gauri Singh and Kashvi Sharma

Ans 5:

Ans 6:

Yes,In the book it is said that the patient should be made sit and lean forward not backward and patient should be told to pinch the sides of the nose together. So the answer should be C.

the answer should "a" as acclimatisation not adaptation

Ans 2:

Class : Class 8
the answer should "a" as acclimatisation not adaptation

Ans 3:

Class : Class 4

Ans 4:

Class : Class 8
the answer should "a" as acclimatisation not adaptation

Ans 5:

Class : Class 4
Acclimatization and adaptation mean two totally different things. Adaptation means permanent adjustment to our habitat whereas acclimatization means temporary adjustment to a place where we temporarily stay for some time and get used to. In my opinion, option A is the right answer.

Ans 6:

Class : Class 8
the answer should "a" as acclimatisation not adaptation

Ans 7:

Class : Class 8
the answer should "a" as acclimatisation not adaptation

Ans 8:

Class : Class 8
the answer should "a" as acclimatisation not adaptation

Ans 9:

Class : Class 8
the answer should "a" as acclimatisation not adaptation

Ans 10:

Class : Class 8
the answer should "a" as acclimatisation not adaptation

Ans 11:

Class : Class 6
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......................................................................

I agree with ANUBHA MAHAJAN as friction does not always oppose the motion.

Ans 3:

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 4:

Class : Class 9
But friction always opposes motion...then how are they saying that option c is true?

Ans 5:

Class : Class 8
Friction not always opposes motion, it opposes the relative motion but they should've given examples of it. I have read it in a book but there is no examples there, too. :-?

Ans 6:

Class : Class 8
Why dont they update the answers and options?? THERE SHOULD BE A NEW OPTION HERE

Ans 7:

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 8:

Class : Class 8
You

Ans 9:

Class : Class 8
Statement 2 is correct while Statement 1 incorrect as frictions is defined as a force which opposes motion and it would not be frictional force if it is not opposing motion that why there has to be a option E.

Ans 10:

Class : Class 8
statement 1 is falsewhereas statement 2 should be true

Ans 11:

Class : Class 9
YES THERE IS A LOT OF ERROR IN THE OPTIONS

Ans 12:

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 13:

Class : Class 9

Ans 14:

Class : Class 9
Statement 1 is false while Statement 2 is true

Ans 15:

Class : Class 5

Ans 16:

Class : Class 8
IT 'S ANSWER SHOULD BE D?

Ans 17:

Class : Class 9
It should be E first statement is incorrect while second statement is correct.

Ans 18:

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 19:

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 20:

Class : Class 9
No statement 1 is correct where as statement 2 is also correct

Ans 21:

Class : Class 5
all the options are incorrect as statement 1 is false and statement 2 is true.so the answer should look like:(iv)none of these

Ans 22:

Class : Class 7
Technically, all of the options are incorrect, as Statement 1 is false and Statement 2 is true.
