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 6:
Class : Class 8
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 7:
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
Ans 8:
Class : Class 6
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)

Here, in this example, the pendulum passes through y 21 times. So, it will do 10 complete oscillations and 1 half which is basically touching y. Therefore, the time period of the pendulum is T/10.
Ans 16:
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

We can express process v as deposition and how did condensation and freezing get involved
Ans 13:
Class : Class 7
Guys you are wrong process name is deposition but you need to cool it to water then freeze it
Ans 16:
Class : Class 8
Answer is B because to turn Water vapour into ice you need Deposition but water vapour cannot be deposited that is why you first need to turn the water vapour to water by condensation and then to convert water to ice you need freezing . Hence answer B is correct

Ans 23:
Class : Class 9
The answer is D. Hair on skin and breast feeding the young ones are characteristic of mammals such as cow. So, if really existed, this animal would have been placed with cow.
Ans 28:

If the animal really existed it would have belonged to the same group as cow.
Ans 30:
Class : Class 5
Firstly , mammals do not have three eyes, secondly which mammal has six legs ???????????
