Ans 1: (Master Answer)

from ,
Class :
The correct answer is C.

Ans 2:

Ayush Gorain from Sarala Birla Public School, Ranchi
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 3:

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

Ans 4:

Rishab Arora from ows, Delhi
Class : Class 9
IT SHOULD BE A

Ans 5:

Rick Banerjee from Calcutta Boys School, Kolkata
Class : Class 8

Ans 6:

Sainyam Sharma from Thakur Public School, Mumbai
Class : Class 8
a is right

Ans 7:

Anvi Jain from School, City
Class : Class 10
C

Ans 8:

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 9:

geetkarthi from SSRVM, Bengaluru
Class : Class 8
How it should be option a

Ans 10:

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 11:

shaurya aggarwal from scholars rosary senior secondary school, rohtak
Class : Class 9

Ans 12:

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 13:

Rishi Ranjan from Phoenix Greens School Of Learning, Hyderabad
Class : Class 8
answer should be A not C

Ans 14:

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

Ans 15:

Sarthak Gupta from Delhi Public School Sector 12 R K PURAM, NewDelhi
Class : Class 10
It should be A

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.

The question and choices given are a bit tricky. The correct answer is A because the language of (iv) is deceptive and says "new trees will grow quickly to replace the burnt ones". You have to understand that "new trees" won't grow quickly, you can only sow small plants not trees.
