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.

Ans 5:

d

Ans 9:

Class : Class 4
it is D because they are going down a slope the more the weight the faster the car goes down right?

Ans 10:

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

Ans 11:

Class : Class 4
Answer should be A car with least no.of people will go faster right

Well,Snow White ,from Paris, I think ASHMI is saying that the answer is 'D'.

Ans 14:

Class : Class 6
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 15:

Class : Class 5
OK YOU ARE TELLING THAT AIR BUT E.G., STEEL BALL VS SPONGE BALL IN SLOPE SEE BELLIONS EXPERIMENTS, HE WILL PROVE THAT ON 76TH EXPERIMENT

Ans 16:

Class : Class 8
ASHMI , you are confusing me and others also I think . Firstly you said - please explain then you said the answer is A then in the experiment in first line you said the answer is D but in the last line you wrote the answer is A !!!!! C an you explain what is the correct answer in your eyes A or D ?

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

Ans 3:

Class : Class 3
It should be D, large intestine

Ans 4:

Class : Class 4
the answer is D large intestine

Ans 5:

Class : Class 4

Ans 6:

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 10:

Class : Class 6
large intestine

Ans 11:

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

Ans 12:

Class : Class 6
It is D large intestine

Ans 13:

Class : Class 4
ANSWER IS D BECAUSE ABSORPTION OF WATER FROM THE FOOD IS DONE BY LARGE INTESTINE

Ans 14:

Class : Class 5
Yes, I also think it is Option D) Large Intestine

Ans 15:

Class : Class 3

Ans 16:

Class : Class 5
4 large interstine

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
