Ans 5:

Harsh Shukla from DPS Bangalore East, Bengaluru
Class : Class 9
question is wrong . the question should be which of the following are correct ?

Ans 6:

sudeep from DPS, Bangalore
Class : Class 8
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 7:

Shikhar Mallick from Holy Cross School, Agartala
Class : Class 7

Ans 8:

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 9:

Vartika Agarwal from Phoenix world school, Pune
Class : Class 9
A option is the correct answer

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 13:

KEERTHANA SHIBU from INDIAN SCHOOL GHOUBRA, Oman
Class : Class 7
oh oh people see they said TRANSPARENT SHEET OF THE PLASTIC BOTTLE SIZE!!that gives the clue that there is another screen behind both those things...vedant amonger you're absolutely right!!!!others all wrong:(

Ans 14:

pranil mishra from KVS, bhubaneswar
Class : Class 10
the correct answer is d because shadows don"t form in a transparent object

Ans 15:

Vedang Amonkar from Dr K B Hedgewar High School, Panaji
Class : Class 6
solution: *the shadow will form on the screen*. maybe it says the shadow will form on a screen behind the transparent sheet. and that point of view it is true. best of luck all

Ans 16:

Akshara from NPS, Bengaluru
Class : Class 8
Answer shud be B.. The question is unclear. They have mentioned what the screen here is supposed to be 😪

Ans 17:

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:)
