Ans 5:

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 6:

Class : Class 9

Ans 7:

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

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

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 7:

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

Ans 8:

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.

Ans 9:

Class : Class 5
Planet D is Uranus which is mostly rocky and icy. I do not understand why it is not A and D. someone please clarify.

Ans 9:

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

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 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 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 14:

Class : Class 8

Ans 15:

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

Ans 16:

Class : Class 8

Ans 17:

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

Ans 18:

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 1:

Class : Class 8
a is right

Ans 2:

Class : Class 8

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

Ans 5:

Class : Class 9

Ans 6:

Class : Class 9
IT SHOULD BE A

Ans 7:

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

Ans 8:

Class : Class 6
answer should be A not C

Ans 9:

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 10: (Master Answer)

Class : Class 1
The correct answer is C.

Ans 11:

Class : Class 10
It should be A

Ans 12:

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

Ans 13:

Class : Class 6
It should be A not C.

Ans 14:

Class : Class 8
How it should be option a
