'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

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 4:

Class : Class 4
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.

You're right!!!!!LAVANYA...

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.

Ans 10:

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 3:

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 4:

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

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

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

Ans 11:

Ans 12:

Class : Class 9
*NO CLEAR EXPLANATION IS GIVEN

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 15:

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 16:

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

Ans 4:

Ans 5:

Class : Class 9
IT SHOULD BE A

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 6
It should be A not C.

Ans 8:

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

Ans 9: (Master Answer)

Class : Class 1
The correct answer is C.

Ans 10:

Class : Class 6
answer should be A not C

Ans 11:

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

Ans 12:

Class : Class 10
C

Ans 13:

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 14:

Class : Class 10
It should be A

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.
