The metal is a magnetic material and like poles repel each other, so there is no conclusion about magnetic field passing through the metal

metals are ferrous so they redirect

Ans 7:

Class : Class 9
ya clearly the magnets are getting attracted to the metal it should be option C.

Ans 8:

Class : Class 6
yes it should be c as the metal bar is attracting the two magnetic bars.

Ans 9:

Class : Class 8

Ans 10:

Class : Class 6
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 11:

Class : Class 6
Basically it’s c because you see the magnets are clearly attracting

Ans 12:

Class : Class 10
magnetic field can pass through metal. but her is such condition where metal is magnetic so it attract both magnet

Class : Class 1
The correct answer is C.

Ans 3:

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 4:

Class : Class 10
It should be A

Ans 5:

Class : Class 9
IT SHOULD BE A

Ans 6:

Class : Class 9
its not a straight line...thus answer SHOULD be A and not C

Ans 7:

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:

Class : Class 6
It should be A not C.

Ans 9:

Class : Class 8
I don't think it could be 'C' since uniform motion generally shows a straight line. Could be 'A'

Ans 10:

Class : Class 8
a is right

Ans 11:

Class : Class 9

Ans 12:

Class : Class 10
C

Ans 13:

Class : Class 10
Shouldn't the answer be option A instead of C as it is clearly not a straight line?

Ans 14:

Class : Class 8
How it should be option a

Ans 15:

Class : Class 7
answer should be A not C

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.

Sun 's surface is about 6000 degrees celcius and blue star is 28000 degrees celcius so to find the answer 28000 -6000 which equals to 22000degrees celcius is blue star hotter than Sun .
