Answer:

Fossil B was found at a depth of 185 meters below Earth's surface, while fossil A was found at a depth of 50 meters below Earth's surface.

Explanation:

I hope this is an answer choice but this would support fossil B being older than fossil A bc the deeper the fossils are in the earth’s surface means that its older.

Answer:

The nucleus (center).

Explanation:

The atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged). Atoms have different properties based on the arrangement and number of their basic particles.

Explanation:

The atomic number of an atom is also the number of proton in an atom.

Answer:

The larger the atom, the lesser the tendency for the atom to withhold its valence electrons.

Explanation:

The size of an atom is usually estimated in terms of its atomic radius. Across the period in the periodic table, the atomic radius decreases progressively from left to right. This is due to the progressive increase in the nuclear charge (i.e., the number of protons in the nucleus) without an attendant increase in the number of electronic shells.

Similarly, down the group, the atomic radius increases progressively from top to bottom due to the successive number of electrons' shells.

Thus, the larger the atom's radius, the smaller the Ionization energy because of the increasing shielding effect of inner shell electrons on the electron to be removed from the nuclear attraction.

Finally, we can conclude that as the atom becomes larger, the tendency to withhold the electrons on the outer shell decreases due to distance and the shielding/ screening effect.

First we need to find the wavelength from the frequency using [tex]C = \lambda V[/tex]

so [tex]3.0e8 = \lambda * 2.2e16 Hz[/tex] which equals 1.36e-8 m then we use the formula [tex]E =h \frac{C}{\lambda}[/tex] we plug in [tex]E = 6.63e-34 * (3.0e8/1.36e-8)[/tex] and we get [tex]E = 1.46e-17[/tex]

so the energy is 1.46 x 10^-17 J.

Explanation:

An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in size from those that are so weak that they cannot be felt to those violent enough to propel objects and people into the air, and wreak destruction across entire cities. The seismic of an area is the frequency, type, and size of earthquakes experienced over a period of time.

the word earthquake is used to describe any seismic event—whether natural or caused by humans that generates seismic waves. Earthquakes are caused mostly by rupture of geological faults but also by other events such as volcanic activity, landslides, mine blasts, and nuclear tests. An earthquake's point of initial rupture is called its hypo center or focus. The epicenter is the point at ground level directly above the hypo center. Tectonic earthquakes occur anywhere in the earth where there is sufficient stored elastic strain energy to drive fracture propagation along a fault plane. The sides of a fault move past each other smoothly and aseptically only if there are no irregularities or asperities along the fault surface that increase the frictional resistance. Most fault surfaces do have such asperities, which leads to a form of stick-slip behavior. Once the fault has locked, continued relative motion between the plates leads to increasing stress and therefore, stored strain energy in the volume around the fault surface. This continues until the stress has risen sufficiently to break through the asperity, suddenly allowing sliding over the locked portion of the fault, releasing the stored energy.This energy is released as a combination of radiated elastic strain seismic waves,frictional heating of the fault surface, and cracking of the rock, thus causing an earthquake. This process of gradual build-up of strain and stress punctuated by occasional sudden earthquake failure is referred to as the elastic-rebound theory. It is estimated that only 10 percent or less of an earthquake's total energy is radiated as seismic energy. Most of the earthquake's energy is used to power the earthquake fracture growth or is converted into heat generated by friction. Therefore, earthquakes lower the Earth's available elastic potential energy and raise its temperature

There are three main types of fault, all of which may cause an inter-plate earthquake: normal, reverse , and strike-slip. Normal and reverse faulting are examples of dip-slip, where the displacement along the fault is in the direction of dip and where movement on them involves a vertical component. Normal faults occur mainly in areas where the crust is being extended such as a divergent boundary. Reverse faults occur in areas where the crust is being shortened such as at a convergent boundary. Strike-slip faults are steep structures where the two sides of the fault slip horizontally past each other; transform boundaries are a particular type of strike-slip fault. Many earthquakes are caused by movement on faults that have components of both dip-slip and strike-slip; this is known as oblique slip.

Reverse faults, particularly those along convergent plate boundaries, are associated with the most powerful earthquakes, mega thrust earthquakes, including almost all of those of magnitude 8 or more. Strike-slip faults, particularly continental transforms, can produce major earthquakes up to about magnitude 8. Earthquakes associated with normal faults are generally less than magnitude 7. For every unit increase in magnitude, there is a roughly thirty fold increase in the energy released. This is so because the energy released in an earthquake, and thus its magnitude, is proportional to the area of the fault that ruptures,and the stress drop. Therefore, the longer the length and the wider the width of the faulted area, the larger the resulting magnitude. The topmost, brittle part of the Earth's crust, and the cool slabs of the tectonic plates that are descending down into the hot mantle, are the only parts of our planet that can store elastic energy and release it in fault ruptures. Rocks hotter than about 300 °C (572 °F) flow in response to stress; they do not rupture in earthquakes.The maximum observed lengths of ruptures and mapped faults (which may break in a single rupture) are approximately 1,000 km (620 mi). Examples are the earthquakes in all in subduction zones. The longest earthquake ruptures on strike-slip faults. are about half to one third as long as the lengths along subducting plate margins, and those along normal faults are even shorter.

In order to determine an objects location, you need to know the speed of the object by which it is moving.

Speed (commonly referred to as v) of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.The average speed of an object in an interval of time is the distance travelled by the object divided by the duration of the interval;the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero. Speed is not the same as velocity.

Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second (m/s), but the most common unit of speed in everyday usage is the kilometre per hour (km/h) or, in the US and the UK, miles per hour (mph). For air and marine travel, the knot is commonly used.

Answer:

1) Metalloids Metalloids, also called semiconductors, are the elements that border the zigzag line on the periodic table. Chemical Symbol Each square on the periodic table includes an element's name, chemical symbol, atomic number, and atomic mass.

2) Atom – the smallest particle into which an element can be divided and still be the same substance. 2. Electrons – the negatively charged particles found in all atoms.

3) Electrons are the negatively charged particles of atom. Together, all of the electrons of an atom create a negative charge that balances the positive charge of the protons in the atomic nucleus. ... The mass of an electron is almost 1,000 times smaller than the mass of a proton.

4) Carbon-13 (13C): The carbon isotope whose nucleus contains six protons and seven neutrons. This gives an atomic mass of 13 amu. six neutrons, resulting in an atomic mass of 12 amu.

5) Atoms are constructed of two types of elementary particles: electrons and quarks. Electrons occupy a space that surrounds an atom's nucleus. Each electron has an electrical charge of -1. Quarks make up protons and neutrons, which, in turn, make up an atom's nucleus.

6) Neutrons are the particles in an atom that have a neutral charge. They aren't positive like protons. They aren't negative like electrons.

7) The current model of the atom shows an atom that is mostly empty space. In the center is a small nucleus made of protons and neutrons.

8) The mass number of an atom is equal to the number of protons plus the number of neutrons that it contains. In other words, the number of neutrons in any atom is its mass number minus its atomic number. Although all atoms of a given element must have the same atomic number, they need not all have the same mass number.

9) Mendeleev arranged the elements in order of increasing relative atomic mass . When he did this he noted that the chemical properties of the elements and their compounds showed a periodic trend .

10) Letter: C

Answer:

If the average kinetic energy of the particles (temperature) remains the same, the average force per particle will be the same. With more particles there will be more collisions and so a greater pressure.

Answer:

So, to determine the number of neutrons in atom, we only have to subtract the number of protons from the mass number. # of neutrons = Mass Number - Number of Protons To be able to apply this formula, refer to the atomic number and atomic weight of the elements. These two are listed in the Periodic Table of Elements.

Answer:

(NH4)2Se

Explanation:

The  chemical formula for  compound ammonium selenide is (NH₄)₂Se.

Here's a step-by-step explanation of how we arrive at this formula:

1. Ammonium ion: The ammonium ion is represented by the formula NH₄⁺. It consists of one nitrogen atom (N) bonded to four hydrogen atoms (H).

2. Selenide ion: The selenide ion is represented by the formula Se₂⁻. It consists of one selenium atom (Se) with a charge of -2.

3. Combining the ions: To form a neutral compound, we need to balance the charges of the ions. Since the ammonium ion has a charge of +1 and the selenide ion has a charge of -2, we need two ammonium ions to balance the charge of one selenide ion.

4. Formula: Therefore, the formula for ammonium selenide is (NH₄)₂Se, indicating that two ammonium ions are required for each selenide ion.

Thus, ammonium selenide has chemical formula of (NH₄)₂Se.

Answer:

The motorcycle's speed after three seconds of acceleration is 18 [tex]\frac{m}{s}[/tex]

Explanation:

Acceleration is a vector quantity that relates changes in speed to the time it takes to occur. Its unit of measurement, in the International System is meters per second squared [tex]\frac{m}{s^{2} }[/tex].  This is expresed as:

[tex]acceleration= \frac{change in speed}{time}[/tex]

Acceleration relates changes in speed with the time in which they occur, that is, it measures how fast changes in speed are:

In this case you know:

Replacing:

[tex]6 \frac{m}{s^{2} } = \frac{speed}{3 seconds}[/tex]

Solving:

speed= [tex]6\frac{m}{s^{2} }[/tex] * 3 seconds

speed= 18 [tex]\frac{m}{s}[/tex]

The motorcycle's speed after three seconds of acceleration is 18 [tex]\frac{m}{s}[/tex]
