Ans 3:

Class : Class 8
Bulb Y will still continue to glow if both the switches are open because bulb Y is directly connected to the battery and both of its terminals are connected to the battery. The answer to the given question is option b.

Ans 8:

Class : Class 6
The answer is (B) because there are no switches in the ire that are being connected to bulb Y. Hence, bulb Y can glow but bulb X can't because S1 is not closed.

but s1 is closed so then the current can come to x too. no?

Ans 11:

Class : Class 8
But it will still remain as an open circuit... there may not be continuous flow of electricity 🤷‍♀️

Ans 3:

Class : Class 5
The planet c is Jupiter the Largest and in a option it is given 2nd largest so it is incorrect but in c option it is written that a and b are made up rocks and it is also incorrect . So the answer should be a and c both .please update the question

Ans 4:

Class : Class 5
'c' is jupiter which is the biggest the answer is 'd' . Saturn is the second biggest planet . if they were asking about the biggest heavenly body in our solar system then options 'a' and 'd' would have been correct as the sun is the biggest heavenly body in our solar system and Jupiter is second

I didn't understand that d is Uranus and it's called the ice giant then why option d is saying that c and d are made up of gases. as per my understanding two options are incorrect, A and D.

Ans 8:

Class : Class 5
Sorry for the misconception , the answer is d

Ans 9:

Class : Class 6
The answer should be A. I understand what you are saying but look they told that the planets C and D are gases. They did not asked how big they are but they asked are they made up of gases. So the answer should be A since C is the largest.

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

Ans 2:

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 3:

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 4:

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

Ans 5:

Class : Class 6
metals are ferrous so they redirect

Ans 6:

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 7:

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

Ans 8:

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

Ans 18:

Class : Class 6

Ans 19:

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

How it should be option a

Ans 4:

Class : Class 6
It should be A not C.

Ans 5:

Class : Class 8
a is right

Ans 6:

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 7:

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

Ans 8:

Class : Class 8

Ans 9:

Class : Class 9

Ans 10:

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 11:

Class : Class 9
IT SHOULD BE A

Ans 12:

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

Ans 13:

Class : Class 10
It should be A

Ans 14: (Master Answer)

Class : Class 1
The correct answer is C.

Ans 15:

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