Basically it’s c because you see the magnets are clearly attracting

Ans 8:

from Gitanjali Public School ,
Class : Class 8
The metal is a magnetic material and like poles repel each other, so there is no conclusion about magnetic field passing through the metal

Ans 9:

Aarushi Vora from Utpal Shanghvi Global School, Mumbai

c is correct since the two magnets seem to be moving to the metal by the angle of the suspension string in the diagram. That means the partition is soft metal

Ans 1:

Anvi Jain from School, City
Class : Class 10
C

Ans 2:

Nishchay Gupta from Cambridge Court World School, Jaipur
Class : Class 6
It should be A not C.

Ans 3:

Rick Banerjee from Calcutta Boys School, Kolkata
Class : Class 8

Ans 4:

Pushkar Sonnekar from Ryan International School, Mumbai, Vasai East
Class : Class 8
I don't think it could be 'C' since uniform motion generally shows a straight line. Could be 'A'

Ans 5:

Rishab Arora from ows, Delhi
Class : Class 9
IT SHOULD BE A

Ans 6:

Vartika Agarwal from Phoenix world school, Pune
Class : Class 9
its not a straight line...thus answer SHOULD be A and not C

Ans 7:

Ayush Gorain from Sarala Birla Public School, Ranchi
Class : Class 8
In my opinion, the answer to this question should by option (A), not option (C). The line is not straight, so it should be non-uniform motion, as a distance-time graph of a body moving in uniform motion should have a straight line.

Ans 8:

geetkarthi from SSRVM, Bengaluru
Class : Class 8
How it should be option a

Ans 9:

Souvik Bhattacharya from MVM, Hyderabad
Class : Class 10
Shouldn't the answer be option A instead of C as it is clearly not a straight line?

shaurya aggarwal from scholars rosary senior secondary school, rohtak

Ans 11:

Sainyam Sharma from Thakur Public School, Mumbai
Class : Class 8
a is right

Ans 12:

Sarthak Gupta from Delhi Public School Sector 12 R K PURAM, NewDelhi
Class : Class 10
It should be A

Ans 13: (Master Answer)

Admin from revisewise, Noida
Class : Class 1
The correct answer is C.

Ans 14:

Rishi Ranjan from Phoenix Greens School Of Learning, Hyderabad
Class : Class 6
answer should be A not C

Ans 15:

Adhrit from CHSV, Chennai
Class : Class 8
It should be A as uniform motion is a single straight line, here there are 3 discrete lines with different slopes. Clearly, the velocity changes at the bold points on the graph, making this non-uniform motion.

Ans 1:

Shalin Jain from NKDAV Sidheegram, Sidheegram
Class : Class 9
Option D because Kinetic energy means work done. Therefore, it can be said that work is done on body or can be said mass. W = F*D(Force * Displacement). Therefore it is independent of mass.
