Answer:
1.False
2.4 E
Explanation:
1.We have to find the statement is true or false.
We know that
Time constant,
Time constant is inversely proportional to resistance R .It means when R increases then time constant decreases when R decrease then the time constant decreases.
Statement:The larger the value of R ,the longer it takes the circuit to reach its final steady- state value
It is false.
2.Energy stored in inductor,E=
When I'=2I
Then, 
Hence,the new total energy will become 4 E.
Matter can absorb light only in certain specific amounts.
Answer:
The correct answer is: A HARD DISK
Explanation:
Magnetic Disc stores data of different types and formats that can always be edited or erased at any time. An example of a Magnetic Disc is a Hard Disk.
A hard disk is a type of magnetic storage device inside a computer that store data magnetically usually for the long-term and it could store a large volume of data, though that depends on the size, because it comes in various size. However, it generally allows stored data to be retrieved easily.
