The answer is correct, as when friction occurs, obviously, all of its properties will occur, even if not all of the properties are required. That's... how friction works.

Ans 2:

Class : Class 8
All the properties friction are in use. Hence, the correct one option 'D'.

Ans 3:

Class : Class 8
The Options Are wrong because only 123 are in use.

Ans 4:

Class : Class 7
The Options Are wrong I guess because only (i),(ii)and(iii) are in use

Ans 5:

Class : Class 8
It's not asking about which properties occur (which would be all of them), it's asking which are in use. And that's only 1, 2, and 3. So the options are wrong

Mass is the amount of matter present in an object whereas weight is the force exerted by the gravity on that object.

Now, the weight of an object, W = g X m, where 'g' is Earth's gravitational constant and 'm' is the mass of the object.

The weight of the object will remain constant as long as the mass of that object is not changing since 'g' is constant. However, the weight of an object can still be changed without changing the mass. This can be explained by the following example: Consider a helicopter with a mass, 'm'.

1. If the helicopter is accelerated towards the earth (during landing) with an acceleration equals to 'A' (positive acceleration) then its weight would become, W = (g + A) X m,  and hence, the weight would increase.

2.  If the helicopter is accelerated away from the earth (during take-off) with an acceleration equals to '- A' (negative acceleration) then its weight would become, W = (g - A) X m,  and hence, the weight would decrease.

Hey, anyone wants to explain to me why it is option C?

Ans 3:

Class : Class 6
In the options, it is written wrong because it is mechanical , kinetic energy. Instead of that it should be muscular, kinetic energy

The correct answer is CRhinoceros does not have scales on body

Ans 2:

Class : Class 4
Do lizards really have scales? I don't think so.

Ans 3:

Class : Class 1
Honestly, if you ask me,I chose snake as the answer because they can peel of their skin while the others can’t. So,Arumolzhi Ramesh I was thinking the same thing. But SOF and most of you guys say that the correct answer is C Rhinoceros as they do not have scales while the other three do. So it must be correct although I did not know lizards had scales on their bodies but as a matter of fact, they do so C must be the correct answer.

Ans 4:

Class : Class 9
Snakes can peel their skin of while the others can’t

Ans 5:

The correct answer is CRhinoceros does not have scales on body while snake, lizard and fish have scales as body covering

Ans 6:

Class : Class 5
I chose snake too, so Biju Pappachan and Arumolzhi Ramesh, I have the same thought process- it sheds its skin.

Ans 7:

Class : Class 1
Google says lizards have scales.

Ans 8:

Class : Class 5
I ticked the answer as D because fish have gills but the others dont

Ans 9:

Class : Class 7
Correct is c because rhino does not have scales while others do

Ans 10:
