Kelvin is the SI unit of temperatureSo both A and D are in correct

Ans 10:

Vidwat Amal from Podar International School , Anand
Class : Class 8
A, B, D are correct....incorrect is C. Because forearm is the length of the arm between elbow joint and wrist joint but the cubit is length from tip of elbow to the tip of the middle finger. so forearm length is smaller than the cubit. So answer is option C

Ans 11:

sudeep from DPS, Bangalore
Class : Class 7
kelvin is the SI unit of temperature so option D is correct and A is also correct because rectilinear motion is motion in a straight line like a car moving on a straight road

Ans 12:

Vidwat Amal from Podar International School , Anand
Class : Class 8
why A is correct and not incorrect because a vehicle need not go in rectilinear path on a straight road it can go zigzag as well

Ans 19:

Akshara from NPS, Bengaluru
Class : Class 8
In the solutions , it says that a colored plastic bottle is a opaque material... However , it is actually a translucent material...:( Maybe since the coloured bottle is translucent , a faint shadow will be seen.. So , here it says that no shadow will be seen at all , which I think is false.. Hope this helps:)
