Which of the following statements are correct?
(i) Human body is a good conductor of electricity.
(ii) The air gap surrounding an electric circuit acts as a conductor.
(iii) Silver conducts electricity better than any other metal.
(iv) When electricity lights up a bulb, no heat is produced.

A (i) and (ii)
B (iii) and (iv)
C (i) and (iii)
D (ii) and (iii)


Can someone explain how the human body is a good conductor of electricity?

Ans 1:

Class : Class 6
actually our human body consists 70% of water and if we touch electricity they are conducted through our body to either to another person or to any metal or to directly the ground.

Ans 2:

Class : Class 8
CORRECT ANS IS D

Ans 3:

Class : Class 7
IDK but I think that I did not read the options properly

Ans 4:

Class : Class 6
because our body contains minerals like iron and has a large quantity of un - distilled water

Ans 5:

Class : Class 6
Answer (C) is correct because our body is a good conductor of electricity and it has even been mentioned in the synopsis. Now, that means that (i) is correct so automatically B and D get canceled. The air in no form acts as a conductor and is an insulator. So C is also canceled. This leaves us with our final aswer A.

Label the dry cell in the correct order.


A (i) Carbon and Manganese dioxide mixture, (ii) Carbon rod, (iii) Ammonium chloride
B (i) Carbon rod, (ii) Ammonium chloride, (iii) Zinc container
C (i) Ammonium chloride, (ii) Zinc container, (iii) Carbon rod
D (i) Zinc container, (ii) Carbon rod, (iii) Carbon and Manganese dioxide mixture


The correct answer is C as the part labeled (i) is ammonium chloride, (ii) is zinc container and (iii) is carbon rod.

Ans 1:

Class : Class 3
All answers are wrong - even 'D' and 'C'. 'C' would, however, be right if the line for '(ii)' was a little shorter.

Ans 2:

Class : Class 6
actually none of the answers are correct

Ans 3:

Class : Class 7

Ans 4:

Class : Class 7

Ans 5:

Class : Class 10

Ans 6:

Class : Class 7
the answer is c as (iii) is a carbon rod and only option c has that

I COULD NOT UNDERSTAND ??

Ans 20:

Class : Class 9
c is the only correct ans because in a zinc carbon dry cell zinc container is the negative terminal of the cell and carbon is the positive terminal of the cell and we need a electrolyte to convert chemical energy into electrical energy i.e. ammonium chloride.

Ans 21:

Class : Class 3
ANS is D!!!!!!!!!!!!!!!!!!!!!!!!!!

Ans 22:

Class : Class 8
I think D is correct

Ans 23:

Class : Class 8
D is the correct answer

Read the given paragraph where few words have been italicised. Rain is our main source of water. Water vapours present in the air precipitate to form clouds. When rain falls, some of it condenses back to atmosphere and some passes through the soil upto the level of non-porous rocks beneath to form groundwater. Groundwater may come out at some places to form water table. Select the incorrect option regarding this.

APrecipitate should be replaced with condense.
BCondenses should be replaced with evaporates.
CGroundwater should be replaced with run-off.
DWater table should be replaced with spring.


Ans 1:

Class : Class 6
yes a is the correct answer

Ans 2:

Class : Class 9
Actually,water does not ''Precipitate'' to form clouds.As long as my memory tells me, water ''Condenses'' to form clouds.
