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

d

the answer a

Ans 5:

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.

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 ?

Ans 7:

Class : Class 5
Answer is D

Ans 10:

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

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 12:

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.

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 9:

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

Ans 10:

Class : Class 3
It should be D, large intestine

Ans 11:

Class : Class 2
D is the answer

Ans 12:

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

Ans 13:

Class : Class 7
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 14:

Class : Class 4
the answer is D large intestine

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

correct option is not given

Ans 7:

Class : Class 10
Gravitational force decreases when altitude increases as gravity is inversely proportional to square of distance that separates earth and the body

Ans 8:

Class : Class 9
answer given is wrong

ALL THE OPTIONS ARE INCORRECT

Ans 10:
