Class : Class 6
correct answer=c

Ans 2:

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 3:

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

Ans 4:

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

Ans 5:

Class : Class 6
The correct answer is c, not d lost a frikin mark

Ans 7:

Class : Class 6
metals are ferrous so they redirect

Ans 8:

Class : Class 6

Ans 9:

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

Ans 10:

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

Ans 11:

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 12:

Class : Class 6
1st a fall the solution is wrong .By any chance (if it could be0.000000000000000000000000001)so how striking process is working . It passes magnetic field. how sus

Ans 13:

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 14:

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 17:

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

Class : Class 9
IT SHOULD BE A

Ans 2:

Class : Class 8
How it should be option a

Ans 3:

Class : Class 9

Ans 4:

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

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

Ans 7:

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 8:

Class : Class 10
C

Ans 9:

Class : Class 8
a is right

Ans 10:

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 11:

Class : Class 10
It should be A

Ans 12:

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

Ans 13:

Class : Class 6
It should be A not C.

Ans 14:

Class : Class 7
answer should be A not C

Ans 15: (Master Answer)

Class : Class 1
The correct answer is C.

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 .

first of all the answer itself is wrong even if its B shouldn't be q repelling p not vice versa

Ans 3:

Class : Class 10
B is the answer because like poles repel.

Ans 4:

Class : Class 10
the fig is wrong because the in the fig there should be repeltion and they have given attraction.
