Most of our knowledge about Earth's interior comes from Seismic waves. Thus, option C is correct.

<h3>What is seismic waves</h3>

Seismic waves are created by abrupt movement of elements within the Earth, including fault rupture during an earthquake. Seismic waves can be caused by volcanic eruptions, blasts, landslides, rock slides, and even flowing rivers.

Seismic waves, also known as compressional or longitudinal waves, push and pull the earth in the direction of motion. Seismic waves provide the majority of our information about the Earth's innards. As a result, option C is correct.

A rigid vessel with a volume of 10 m3 contains a water-vapor mixture at 400 kPa. If the quality is 60 percent, find the mass. Th
trapecia [35]
A) The pressure (p)=400kPa=0.400MPa
Mass of mixture =M
quality (X)= 0.60
Volume of mixture (V)=10 m3
From steam table at P=0.400MPa
Specific volume of saturated water (vf)=0.00108355 m3/kg
Specific volume of saturated steam (vg)=0.46238 m3/kg
Therefore, the volume of steam having X=0.6 is given by
V=M[vf+X(vg-vf)]
10= M[0.00108355+0.6(0.46238-0.00108355)]
M=36.04748 kg
If pressure is lowered to 300kPa
p=0.300MPa
From steam table we get,
Specific volume of saturated water (vf)=0.00107317 m3/kg
Specific volume of saturated steam (vg)=0.60576 m3/kg
Therefore, the volume of steam having X=0.6 is given by
V=M[vf+X(vg-vf)]
10= M[0.001007317+0.6(0.60576-0.00107317)]
M= 26.4825 kg

which type of building construction can include materials with no fire-resistance ratings in limited quantities?
hammer [34]

The type of type of building construction can include materials with no fire-resistance ratings in limited quantities is type 2.

Although many buildings appear to be similar at first appearance, their cost and durability—particularly in an emergency—are affected by the underlying materials. Building codes categorize all structures into Types 1 through 5, and each Type discloses important details like fire-resistance.

Some contemporary structures are now stronger and less expensive to construct. Engineered wood and synthetic plastics, which burn readily, cause quick collapses and present significant risks for firefighters.

Type 1 constructions, which are the most fire-resistant buildings, are made of shielded steel and concrete because they can sustain high temperatures without collapsing. Type 5 constructions, on the other hand, are the least fire-resistant since they are built of flammable materials, are lightweight, and they burn out quickly. Type 2 constructions, modern structures with metal roofs and tilt-slab or reinforced masonry walls.
