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

Ans 7:

Class : Class 7
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

Ans 9:

Class : Class 4
The answer is right - it should be T/10

Ans 10:

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)

Shred a paper in tiny pieces. Take a comb and comb your hair. Now bring the comb closer to the paper pieces. What will you observe?

A The paper pieces will get repelled due to magnetic force.
B The paper pieces will get repelled due to electrostatic force.
C The paper pieces will get attracted and stick to the comb due to electrostatic force.
D The pieces will get attracted and stick to the comb due to frictional force.


Ans 1:

Class : Class 5
C

Ans 2:

Class : Class 5
The answer is C

Ans 3:

Class : Class 5
Class :C

Ans 4:

Class : Class 8
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:

Class : Class 6
I prefer option C

Ans 6:

Class : Class 5

Ans 18:

Class : Class 5
Firstly , mammals do not have three eyes, secondly which mammal has six legs ???????????

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.
