The following choices contain densities of various materials. Based on these data, which will yield the fastest seismic velocity
Eduardwww [97]

Answer:

D. 5.6 g/cm^3

Explanation:

On the average seismic velocity increases with increase in depth due higher the pressure and more compaction

sand and shales in the Niger Delta Basin density–velocity relationship is

P = 0.31×V^0.25

A derivation of the original Gardner equation to calculate the average densities for sands and shales in wells.

ρ = α ×V^β

where

ρ = bulk density in g/cm3,

V = P-wave velocity,

α = 0.31 for V (m/s) and 0.23 for V(ft/s) and

β = 0.25.

Such that

ρ = 0.31 ×V^0.25

So the fastest seismic velocity will be in the densest material which is D. 5.6 g/cm3

Calculate the density of a 20.015 g object that occupies 5.44 cm3 .
Scilla [17]

Answer:

density =  \frac{mass}{volume}  \\  \\ density =  \frac{20.015}{5.44}  \\  \\ { \boxed{ \boxed{density = 3.679 \: g {cm}^{ - 3} }}}
