Answer to Problem 39P

The speed of the longitudinal waves in water is 1.4×103 m/s .

Explanation of Solution

Given:

Elastic modulus of water, E = 2×109N/m2

Density of water,  ρ = 1000 kg/m3

Formula used:

The speed of the longitudinal waves in water is obtained by the following formula,

  v =Elastic modulusDensity=Eρ

Here,

  v is speed of longitudinal wave,

  E is elastic modulus,

  ρ is density.

Calculation:

Substitute the given values in the above equation,

  v =2×1091000 = 1.4×103 m/s

Conclusion:

Thus, the speed of the longitudinal waves in water is 1.4×103 m/s .

Answer to Problem 39P

The speed of the longitudinal waves in granite is 4.1×103 m/s .

Explanation of Solution

Given:

Elastic modulus of granite, E = 45×109N/m2

Density of granite,  ρ = 2.7×103 kg/m3

Formula used:

The speed of the longitudinal waves in granite is obtained by the following formula,

  v =Elastic modulusDensity=Eρ

Here,

  v is speed of longitudinal wave,

  E is elastic modulus,

  ρ is density.

Calculation:

Substitute the given values in the above equation,

  v =45×1092.7×103 = 4.1×103 m/s

Conclusion:

Thus, the speed of the longitudinal waves in granite is 4.1×103 m/s .

Answer to Problem 39P

The speed of the longitudinal waves in steel is 5.1×103 m/s .

Explanation of Solution

Given:

Elastic modulus of steel, E = 200×109N/m2

Density of steel, ρ = 7.8×103 kg/m3

Formula used:

The speed of the longitudinal waves in steel is obtained by the following formula,

  v =Elastic modulusDensity=Eρ

Here,

  v is speed of longitudinal wave,

  E is elastic modulus,

  ρ is density.

Calculation:

Substitute the given values in the above equation,

  v =200×1097.8×103 = 5.1×103 m/s

Conclusion:

Thus, the speed of the longitudinal waves in steel is 5.1×103 m/s .
