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 2:

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

Ans 3:

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

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 7:

Class : Class 9
statement 1 is falsewhereas statement 2 should be true

Ans 8:

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 9:

Class : Class 9
I agree with ANUBHA MAHAJAN as friction does not always oppose the motion.

Ans 10:

Class : Class 8
You

Ans 11:

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

Ans 12:

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

Ans 13:

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 14:

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

Ans 15:

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 16:

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 17:

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

Ans 18:

Class : Class 5

Ans 19:

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

Ans 20:

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

Ans 21:

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 22:

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

So, for an experiment you need multiple values for comparison. This question states that the experiment is to be carried out for four days, meaning that you need to compare four different scenarios. The first one is obviously hot and windy. The four scenarios- hot, windy, calm and cloudy must be paired with each other forming these- hot and windy, hot and calm, windy and cloudy, cloudy and calm- option B
