Question

18. The following data show the values of the speed of sound (in m/s) through
medium A, B, C and D :
(i) Why is the speed of sound through medium C 0(m/s) ?
(ii) Identify the most probable physical state of A. Give reason for your
answer.
(iii) Which of the four media could be 'air ?
1+(2+1)+1=3​

Answer 1

Answer:part ii- it is solid medium here sound velocity is 3000 which is possible only where there is strong intermolecular force

Explanation:

Answer 2

Answer:

(i) the speed of sound through medium C Is 0 metre per second because it is a vacuum.

Explanation:

(ii) the physical state of a solid because in solids sound travel the faster.

(iii) medium B Is air.
