Hope this helps you :)
The difference between the arrival time of the first P-wave and the arrival time of the first S-wave recorded at the station will be 6 minutes 40 seconds.
What are Body waves ?P waves move the fastest and arrive first from the earthquake. Rock oscillates perpendicular to the direction of wave propagation in S or shear waves.
In rock, S waves move at approximately 60% the speed of P waves, and the S wave always comes after the P wave. Sound waves, for example, are P waves with a high enough frequency to be heard with your ear.
Wiggling or shaking a rope that is tied down at one or both ends is an example of a S wave.
Both P and S waves propagate outward from an earthquake focal point within the ground.
The waves are frequently observed as independent arrivals on seismographs located at great distances from the earthquake. The direct P wave arrives first because its course takes it through faster moving, denser rocks deeper in the ground.
Because they pass through deeper, lower velocity rocks, the PP (one bounce) and PPP (two bounces) waves move more slowly than the straight P. After the P waves, the various S waves arrive.
To conclude with we can say that Seismic waves or body waves are elastic waves created when the earth's crust is disturbed. The wave is classified into two types body waves and surface waves. The P and S - waves that move through the ground are body waves.

Assume you expand the group of materials you have to test to include metals. The forces that hold the atoms together in a metallic solid, or piece of metal, are referred to collectively as the "electron sea. " This is because, in a metallic solid, electrons do not stay close to a single atom, rather they move through the metal quite readily. The resulting electrostatic force between the positive nuclei of the metal atoms and the negative electrons is very strong and keeps the metal in the solid state. Given this information, describe the results you would expect to observe if you performed the melting point and conductivity tests on a metal sample
If you perform a melting point test on a metal sample, you would expect to observe that the metal has a relatively high melting point compared to non-metallic materials. This is because of the strong electrostatic forces between the positive nuclei of the metal atoms and the negative electrons, which hold the metal atoms together in a tightly packed lattice structure. As a result, a large amount of energy is required to overcome these forces and melt the metal.
Metal samples are expected to be excellent conductors of heat and electricity when a conductivity test is performed on them. This is because electrons in metallic solids move through the metal fairly easily and are free to move around the lattice structure. This free movement of electrons allows heat and electricity to easily pass through the metal, making it highly conductive.

A gas law known as Gay-law Lussac's asserts that a gas's pressure (when kept at a constant volume and mass) varies directly with its absolute temperature
What is Gay- Lussac's Law?A gas law known as Gay-law Lussac's asserts that a gas's pressure (when kept at a constant volume and mass) varies directly with its absolute temperature. In other words, while the mass is fixed and the volume is constant, the pressure a gas exerts is proportional to the temperature of the gas.
In the year 1808, French scientist Joseph Gay-Lussac created this law. Gay-law Lussac's can be expressed mathematically as follows:
P ∝ T ; P/T = k
Where:
P is the pressure that the gas is applying.
T is the gas's actual temperature, while k is a fixed value.
Example of Gay-Lussac lawThe tire pressure of a car increases after driving. This is due to the air inside the tires heating up as a result of friction (a contact force) between the tires and the road. Gay-Law Lussac's states that because the air cannot expand because the tires are effectively fixed-volume containers, the pressure rises.

A gas has a volume of 6.35 L at 88.6 kPa. What will be the volume at standard pressure? Standard Pressure = 101.3 kPa
Answer:
5.55 L
Explanation:
This excersise can be solved by the Boyle's law.
This law for gases states that the pressure of a gas in a vessel is inversely proportional to the volume of the vessel.
P₁ . V₁ = P₂ . V₂
The law comes from the Ideal Gases Law, in the first term.
P . V = n . R . T In this case, n . R . T are all constant.
6.35 L . 88.6 kPa = 101.3 kPa . V₂
V₂ = (6.35 L . 88.6 kPa) / 101.3 kPa
V₂ = 5.55 L
It is inversely proportional because, as it happened in this case, pressure was increased, therefore volume decreased.

The elements with the highest ionization energy are the noble gases, which are located in the upper right corner of the periodic table. These elements include helium, neon, argon, krypton, xenon, and radon. These elements have a full valence electron shell, meaning that they have the maximum number of electrons possible in their outermost energy level. This makes them very stable and resistant to chemical reactions, as they do not have any electrons that can be easily removed or added.
As a result, they have very high ionization energy, meaning that a large amount of energy is required to remove an electron and form an ion. Due to these properties, these elements are not readily reactive with other elements and tend to exist as diatomic molecules or as individual atoms.
