Question

Statement 1:- While playing guitar sound energy is produced.

Statement 2:- Heat energy is converted into sound energy in a guitar.

• A. Statement 1:- True Statement 2:- False
• B. Statement 1:- False Statement 2:- True
• C. Statement 1:- True Statement 2:- True
• D. Statement 1:- False Statement 2:- False

Answer 1

The correct option is A

Statement 1:- True

Statement 2:- False

To play guitar movement of the fingers is required (mechanical energy) which vibrates the strings of the guitar and further sound energy is produced. But the stored energy in the body, i.e., chemical energy (obtained from food) is required for the movement of fingers. Hence, $Chemicalenergy\to Mechanicalenergy\to Heatenergy$.

Therefore the first statement is true but the second statement is false.
