Answer:
Percentage change in tension is 3.8%
Explanation:
We have given initially frequency 
= 440 Hz
Let tension in the string at this frequency is 
Now second frequency is 
Frequency in string is given by
From the relation we can say that
Percentage change in tension is equal to
%
So percentage change in tension is 3.8%
Answer:
The correct option is D) Fission
Explanation:
There are several methods through which Radioactive isotopes are created.
- Using a nuclear reactor that has a field of neutrons, insert a stable sample such as Lutetium-176. When it gets bombarded with neutrons, it acquires some, and fission is said to have occurred. Note that when Lutetium-176 acquires a neutron, it becomes radioactive Lu-177.
- Fission is also used to create Fluorine-18. To obtain the same, you need to bombard pure or enriched [
] water with ~18 MeV protons which are high energy in nature. The bombarding is achieved using a cyclotron or an accelerator.

Answer:
The balloon prohibits the flow of air through the air capacitor.
Explanation:
Just like an electric capacitor has an insulator between the plates, the air capacitor has a balloon between the chambers.
