Question

A glass slab experiences a hydraulic pressure of 8 × 106 N/m2. If the bulk modulus of glass is 3.7 × 1010 N/m2, what is the fractional change in volume?

Options

Choose one · Correct answer highlighted

Explanation

Bulk modulus: B = -p / (ΔV / V). Rearrange: ΔV / V = -p / B. Substitute: ΔV / V = -(8 × 106) / (3.7 × 1010) ≈ -2.16 × 10-4. Magnitude: 2.16 × 10-4.
