<h3>Answer;</h3>

S waves are known as secondary wave or shear waves

<h3>Explanation;</h3>

Seismic wave are types of waves that result from break down of rocks within the earth or an explosion. Seismic waves are classified as body waves and surface waves.
Body waves are classified into either secondary waves or primary waves. Commonly known as the S-waves and the P-waves.
Secondary waves are types of body waves that move through an object's body unlike the case of surface waves. It is the second wave that is felt after an earthquake.

A piece of aluminum has a volume of 1.50 10-3 m3. the coefficient of volume expansion for aluminum is β = 69 ✕ 10-6 (°c)-1. the

Answer:

W = 3.12 J

Explanation:

Given the volume is 1.50*10^-3 m^3 and the coefficient of volume for aluminum is β = 69*10^-6 (°C)^-1. The temperature rises from 22°C to 320°C. The difference in temperature is 320 - 22 = 298°C, so ΔT = 298°C. To reiterate our known values we have:

β = 69*10^-6 (°C)^-1 V = 1.50*10^-3 m^3 ΔT = 298°C

So we can plug into the thermal expansion equation to find ΔV which is how much the volume expanded (I'll use d instead of Δ because of format):

$dV = \beta V_{0} dT\\dV = (69*10^{-6})( C)^{-1} * (1.50*10^{-3})m^{3} * (298)C\\dV = 3.0843*10^-5$
