And is A since X is insulator it doesn't allow electricityTo pass through so nothing glows

Class : Class 7

## Ans 3:

Class : Class 10
The answer is C as if assume x as a insulator , all other condition satisfy

Class : Class 6
Very good question. Here object X is a insulator but the bulbs glow up because of parallel connection of circuit. So according to that, option A is wrong and is the correct answer.

B is the answer to this question but it is showing A as correct option and it is showing B as correct option in the solutions.

## Ans 6:

Class : Class 3
This is absolutely correct as y is cerebrum and x is. EllThis Is absolutely correct as y is cerebrum X is cellebellum and Z is the Medulla âœ…âœ…âœ…âœ…

## Ans 7:

Class : Class 5
Both A and C are correct

Class : Class 4

## Ans 9:

the answer is wrong , it should be 0.2s. please kindly provide the solution to this question.

Class : Class 6

## Ans 7:

Class : Class 8
I think this answer is wrong. It should be 0.2 seconds, according to the definition of a Time Period in oscillatory motion.

## Ans 8:

Class : Class 10
answer is wrong it should be 0.2 s

## Ans 9:

Class : Class 6
The answer should be 0.2 s

Class : Class 7

## Ans 11:

Class : Class 7
I THINK IT COMPLETES 25 OSCILLATIONS IN 5s

Class : Class 4

## Ans 13:

Class : Class 6
The answer has to be 0.2 seconds(5/25). Pls correct

Class : Class 9

Class : Class 7

## Ans 16:

Class : Class 7
The answer seems to be wrong. 5 seconds to complete 25 oscillations. That means for one oscillation it is 5/25 = 0.2 seconds. 'Period' usually means one complete oscillation that is 0.2 seconds and that is not given.

## Ans 17:

Class : Class 7
The time taken to complete one oscillation - a left swing and a right swing - is called the time period (T); it is measured in seconds.A swing takes 5 seconds to complete 25 oscillations. That means it would take 1 second to complete 25 Ã· 5 = 5 oscillations. That also means it would take 1 Ã· 5 = 0.2 seconds to complete 1 oscillation.So, the time period of the swing is 0.2 seconds. Hence, the right answer is Option C.
