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)
Ans 6:
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 10:
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 11:
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 12:
Class : Class 8
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.

Guys you are wrong process name is deposition but you need to cool it to water then freeze it
Ans 5:
Class : Class 6
We can express process v as deposition and how did condensation and freezing get involved
Ans 14:
Class : Class 9
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

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).

The object X is made up of two materials 1 and 2.When the light is shone on it, it casts a shadow on
screen as shown in the picture.
Identify materials 1 and 2 of which object X is made.
| Material 1 | Material 2 | |
| A | Aluminium foil | Thermocol |
| B | Cardboard | Clear plastic sheet |
| C | Clear cellophane paper | Styrofoam |
| D | Thermocol | Cardboard |
is answer B correct?
Ans 1:
Class : Class 8
the answer is c 'cause material 1 is transparent and material 2 is opaque. The solution also says c. Typing error. Thanks for reading
Ans 4:

Ans is c as you see light can't pass through material 2 and can pass through material 1. According to SOF ans b which mean light can pass through cardboard and can't through clear pastic sheet!!!!!. Please correct this SOF or it can be a typing mistake. Thanks for reading.
Ans 7:
Class : Class 8
ANSWER WILL BE 'C ' CAUSE THROUGH TRANSPARENT MATERIAL WE CANNOT SEE SHADOW OF A THING BUT THROUGH OPAQUE MATERIAL WE CAN SEE A THING'S SHADOW
