Question

if ratio of intensity of 2 sounds A and B is 9:16. if amplitude of A is doubled and that of sound B is halved , then ratio of intensity of sound A and B becomes

Answer 1

matter, material substance that constitutes the observable universe and, together with energy, forms the basis of all objective phenomena. ... The three most familiar forms, or states, of matter are solid, liquid, and gas.

Answer 2

Answer:

The correct answer is 49:1.

Explanation:

This can be determined using the following simplified formula:

Maximum intensity/ Minimum intensity ( Imax/Imin) =[ ( a1+a2)/ (a1-a2) ]^2, where a1 is the first amplitude and a2 is the second amplitude

Now putting the values of a1 and a2 in the formula:

Imax/ Imin=[ (4+3)/(4-3) ]^2= 49:1
