Answer 1

Explanation:

v1 , v2 ,v3. air,water, iron

Answer 2

Answer:

The increasing order of the velocities is as  v₁< v₂< v₃.

                                     

Explanation:

Density of the material is one of the factor that affects the velocity of of sound in that material.

Higher is the density of material given higher is the speed of in that material .

Given is v₁, v₂ and v₃ are the velocity of sound in air, water and iron respectively.

Since the density of air, water and iron are in the order,

                                   $D_{iron} > D_{water} > D_{air}$

So the velocity of sound in the given medium is of order

                                   $v_{iron} > v_{water} > v_{air}$

Hence the increasing order of the velocities is as follows,

                                      v₁< v₂< v₃
