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 4:

Shailaja Divakar from Chennai public school global school, London
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 5:

lavanya from bcm chd road, Ludhiana
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 6:

Kushagra Shukla from Presidium dwarka, New Delhi
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

Ayush Gorain from Sarala Birla Public School, Ranchi

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 6:

Anvi Jain from School, City
Class : Class 10
C

Ans 7:

Souvik Bhattacharya from MVM, Hyderabad
Class : Class 10
Shouldn't the answer be option A instead of C as it is clearly not a straight line?

Ans 8:

Vartika Agarwal from Phoenix world school, Pune
Class : Class 9
its not a straight line...thus answer SHOULD be A and not C

Ans 9:

Rick Banerjee from Calcutta Boys School, Kolkata

Ans 10:

Nishchay Gupta from Cambridge Court World School, Jaipur
Class : Class 6
It should be A not C.

Ans 11:

Adhrit from CHSV, Chennai
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 12:

Pushkar Sonnekar from Ryan International School, Mumbai, Vasai East
Class : Class 8
I don't think it could be 'C' since uniform motion generally shows a straight line. Could be 'A'

Ans 1:

Shalin Jain from NKDAV Sidheegram, Sidheegram
Class : Class 9
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.
