Question

if bulk modulus of lead is 8.0 into 10 to the power 9 Newton per metre square and initial density of lead is 11.4 gram per centimetre cube then under pressure of 2.0 into 10 to the power 8 Newton per metre square the density of lead is​

Answer 1

Answer:

Let the initial volume of  lead be  V₁ and  final volume   V₂

Given,

Pressure (p) = 2 ×10⁸ N/m₂

Bulk modulus (B) = 8 × 10⁹ N/m²

If the change  in volume  is  ΔV,

Then,

If  the  mass of  lead  is  m and  initial density is р₁ and  final density is  р₂

m = р₁V₁ = р₂V₂
