correct answer=c

Ans 5:

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

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

Ans 11:

Class : Class 1
Ans. is option C because magnets are attracting the metal piece. They are not attracting each other. SOF Olympiad Trainer, you need to solve this

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

Ans 13:

Class : Class 9
C is correct. Not D. SOF WHY IN THE WORLD WHY ON EARTH YOU MAKE SUCH MISTAKES? THAT TOO NO EXPLANATION GIVEN

Ans 14:

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 15:

Class : Class 6
metals are ferrous so they redirect

Ans 16:

Class : Class 9
the correct answer is not d......................... their mistake they always make such kind of mistakes

Ans 17:

Class : Class 7
Correct answer will be option no. C why it's written option no. D?

Ans 18:

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

Ans 19:

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

Ans 20:

Class : Class 8
The correct answer is C not D........ their mistake ..... you need to solve

Ans 1:

Class : Class 10
It should be A

Ans 2:

Class : Class 8

Ans 3:

Class : Class 10
C

Ans 4:

Class : Class 9
IT SHOULD BE A

Ans 5:

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

Ans 6:

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 7: (Master Answer)

Class : Class 1
The correct answer is C.

Ans 8:

Class : Class 6
It should be A not C.

Ans 9:

Class : Class 9

Ans 10:

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

Ans 11:

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 12:

Class : Class 8
a is right

Ans 13:

Class : Class 8
How it should be option a

Ans 14:

Class : Class 6
answer should be A not C

Ans 15:

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

ans is C. in first row the head count (from right to left ) is 1+1=2, in second row the head count (from right to left ) is 2+1=3,hence in the third row the head count will be 0+2=2, hence the answer is 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 .
