it should be t/10 only as during time period the pendulum will pass through the point y twice.so the time period will be t/10

## Ans 2:

Class : Class 6
It should be T/21 only as T is the total time and no of times it passes Y is 21.Therefore the answer is T/21

## Ans 3:

Class : Class 8
it should be t/10 only as during time period the pendulum will pass through the point y twice.so the time period will be t/10

Yes it should be t/10 as the pendulum will pass through point y twice in its one revolution...... so the the time period should be t/10

## Ans 8:

Class : Class 8
it should be t/10 only as during time period the pendulum will pass through the point y twice.so the time period will be t/10

throughout the time period or the 21 swings the pendulum will pass through the point Y 21 times. so the answer is B(t/21)

NA

## Ans 6:

Class : Class 7
I also agree with all of you . That's just impossible, I guess.

## Ans 7:

Class : Class 6
We can express process v as deposition and how did condensation and freezing get involved

## Ans 8:

Class : Class 6
gas to solid is deposition and opposite is sublimation ans wrong

## Ans 9:

The correct ans is option C because electrostatic force is a non contact force which is similar to magnetic force and the comb is like a magnet and tin pieces of paper are like the metal here (So the comb will attract the tiny pieces of paper).

## Ans 5:

Firstly , mammals do not have three eyes, secondly which mammal has six legs ???????????
