Ans 6:

Class : Class 8
the answer a

This is wrong logic. All the cars will go down with same speed. The acceleration is same for all objects. Only when there is significant air resistance will the speeds be different. E.g., bullet vs. a feather. Look for Galileo's experiment. In this question, the air resistance will not be any different across the 4 choices.

Ans 9:

Class : Class 2
Aaaa

Ans 10:

Class : Class 5
it is D because they are going down a slope the more the weight the faster the car goes down right?

Ans 11:

Class : Class 5

Ans 12:

Class : Class 7
d because the car will go faster with more wieght

Ans 13:

Class : Class 8
Answer is D

Class : Class 2
The correct answer is a

Ans 16:

Class : Class 4
THE ANSWER IS A!

Ans 17:

Class : Class 8
Answer should be A car with least no.of people will go faster right

Answer is D as gravitational force acts quicker on the heavier object.You can try an experiment related to this answer.Throw a plastic bottle cap and metal bottle cap OR a sheet of paper and a glue bottle OR any two such things so that one is heavy and the other one is light. Then throw them from the same height and at the same time. Then you'll get the answer i.e. the heavier thing fell before the lighter thing. I tried this experiment after giving my first opinion (OPTION A-you can see it) and it gave me good results.

Yes, I also think it is Option D) Large Intestine

Ans 5:

Class : Class 6

Ans 6:

Class : Class 3
It should be D, large intestine

Ans 7:

Class : Class 3

Ans 8:

Class : Class 4

Ans 9:

Class : Class 7
ANSWER IS D BECAUSE ABSORPTION OF WATER FROM THE FOOD IS DONE BY LARGE INTESTINE

Ans 10:

Class : Class 5
4 large interstine

Ans 11:

Class : Class 7
Harishchandra, see, clearly, the pic in option 'C' is small intestine.The pic in option 'D' is of large intestine.The answer is option'D'

Ans 12:

Class : Class 10
It is D large intestine

Ans 13:

Class : Class 7
the answer is D large intestine

Ans 14:

Class : Class 6
large intestine

Ans 15:

Class : Class 7
4The answer will be D It is the correct answer

Ans 16:

Class : Class 5
C AND D ALSO WILL ABSORB WATER SO C AND D SEE CORRECT IT SOF

Ans 17:

Class : Class 9
Harishchandra, in option C the figure is of ' Small Intestine ' and in option D the figure is of ' Large Intestine' . So the answer is D

It is reversible and chemical because salt has sodium and chlorine and water has hydrogen and oxygen so different item formed It is reversible because you can separate them by evaporating the water

Gravitational force decreases when altitude increases as gravity is inversely proportional to square of distance that separates earth and the body
