Three test tubes are set up as shown. The indicator used here changes from red to yellow when exposed to increased levels of carbon dioxide. At the start of the experiment, the indicator in each test tube was red.
What will be the colour of the indicator in each test tube after two hours?
| a | b | c | |
| A | Yellow | Yellow | Red |
| B | Red | Yellow | Red |
| C | Yellow | Red | Red |
| D | Yellow | Yellow | Yellow |
Please explain how the test tube with insects will turn yellow.

D, both oscillatory and circular. Because you see, in the pendulum, the length of the string is the same only. Even when it is completely rotated.
Ans 7:
Class : Class 6
In oscillatory, the pendulum is moving at a fixed distance from the axis from which it is hung. It's like an arc of a circle. So, it should be D
Ans 10:
Class : Class 8
Not every oscillatory motion has the distance of the body same from the axis . For example : Motion of a guitar string . Hence the correct answer is B
Ans 14:
Class : Class 6
i think it should be rotational motion ,but among these options ,i think it will be d
Ans 18:
Class : Class 6
It will be D only because the pendulum is the best example for oscillatory motion and the example of circular motion is already given in the solution.
