Question

The elastic deformation energy per unit volume in fresh water of density d and compressability b at a depth h below the surface is

Answer 1

Answer:

the volume density of elastic energy of fresh water at a depth of 1000m

Work done is W=1/2×stress×strain

W=PΔV/2

W/V=PΔV/2V

also, Bulk modulus B=∣−PV/ΔV∣

so, W/V=P

2

/2B

P=ρgh=1000kg/m

3

×10m/s

2

×1000m and B=2×10

9

So W/V=25kJm
