Answer:

There could be several possible reasons for a small gap between rails on a railway track, such as:

1. Expansion joints: Railways are designed to allow the tracks to expand and contract with changes in temperature. To accommodate this expansion, small gaps are left between the rail ends and filled with expansion joints or plates.

2. Wear and tear: Over time, the rails may experience wear and tear due to heavy loads, weather conditions, and other factors. As a result, small gaps can appear between the rails.

3. Maintenance: During maintenance activities, rail tracks may be adjusted or replaced, which could lead to small gaps between the rails.

4. Environmental factors: Environmental factors such as soil shifts, earthquakes or other natural disasters can also affect the alignment of the rails, leading to small gaps.

These are some of the possible reasons for a small gap between the rails on a railway track.

Answer:

The small gap left between the rails in a railway track is intentional and serves a specific purpose. This gap is known as the rail joint, and it allows for the expansion and contraction of the rails due to changes in temperature. When the temperature changes, the metal rails will expand or contract, and if they were joined together tightly, they could buckle or become deformed, which could be dangerous for trains passing over them. The rail joint allows the rails to move slightly and prevent damage to the track.

Additionally, the rail joint also allows for maintenance and repairs of the track. If there were no gap between the rails, it would be challenging to replace a damaged rail or perform routine maintenance, such as tightening bolts or lubricating joints. With the rail joint, maintenance personnel can easily access and work on the track.

Overall, the small gap left between the rails in a railway track is intentional and serves a crucial function in ensuring the safety and reliability of the track.

During a chemical reaction, the most likely occurring is mass conservation. According to law of conservation of mass, total mass in a reaction is conserved.

According to the law of conservation of mass, the total mass in a chemical reaction or in a physical change is conserved. Simply, mass is neither created nor destroyed.

When a chemical reaction takes place,  no new atoms are created and the properties of the reactant species cannot be maintained after reaction.

Molecules of any reactant is not lost during a reaction. The total mass in the reactant side of a balanced reaction will be equal to the total mass in product side.

Therefore, the mass conservation is likely to occur during a chemical reaction. Thus, option d is correct.

1. Magnitude measures the energy released by the earthquake, while intensity measures its duration. The correct option is A.

2. The conclusion you can draw between the two conditions is that there is more likely to be an earthquake in a "highest hazard" location than in a "lowest hazard" location and is denoted as option A.

3. P waves travel fastest and are the first to arrive from the earthquake. In S or shear waves, rock oscillates perpendicular to the direction of wave propagation. In rock, S waves generally travel about 60% the speed of P waves, and the S wave always arrives after the P wave.

4. Seismographs are instruments used to record the motion of the ground during an earthquake. They are installed in the ground throughout the world and operated as part of a seismographic network.

Because it is easier for metals to shed their valence electrons and form cations for a stable configuration, they have comparatively few chances of acquiring electrons.

The metals usually complete their octet in each reaction. The outermost electron shell often contains more electrons in metals. Metal atoms lose electrons when they interact with other non-metals because the energy of an electron in its outermost shell is very weak.

Metals often have low ionization energy because their electrons are positive in nature. Metals lose their electrons and trade them with non-metals to achieve a stable configuration.

The respiration which is seen in plants and higher animals including humans take place in the presence of oxygen.

The process in which the cells of an organism obtain energy by the combination of oxygen and glucose and results in the release of carbon dioxide, water and ATP (energy) is defined as the respiration.

In respiration, the transfer of oxygen occurs from outside environment to cells within the tissues. It is a biological reaction which takes place inside the cells of living organisms. The energy molecule ATP ( Adenosine triphosphate) is created during this process.

The ATP molecule produced here by the breakdown of glucose is utilized by the cells to perform various activities. The first step in cellular respiration is glycolysis which occurs in cytoplasm.

The correct path of oxygen transfer is:

Nostrils → Nasal cavity → Pharynx → Trachea → Bronchi → Bronchiole → Alveoli

Answer:

Under normal circumstances, this molecule is quite stable. If heated, though, it will fall apart. The chemical equation 2 NaN3 --> 2 Na + 3 N2 describes exactly how it falls apart. Notice that the second product of the above reaction is N2, also known as nitrogen gas. A handful (130 grams) of sodium azide will produce 67 liters of nitrogen gas--which is enough to inflate a normal air bag.

Explanation: Because of mathmaticsit works

Nitrogen gas (N2) and sodium metal (Na) are the products of the breakdown of sodium azide.

Metal is defined as a solid with good electrical and thermal conductivity that is often hard, glossy, malleable, fusible, and ductile. The majority of metals are ductile and malleable, and they are often denser than other elements. The materials that have a propensity to donate electrons are metals. They have an electropositive makeup.

Airbags are inflated by nitrogen gas in less than a tenth of a second! Because to this design, occupants of cars are less likely to suffer severe injuries in collisions. Sodium azide, often known as NaN3, is the principal chemical involved in the air bag reaction. As a result of the heat produced, sodium azide breaks down into sodium metal and nitrogen gas, inflating the car's air bags.

Thus, nitrogen gas (N2) and sodium metal (Na) are the products of the breakdown of sodium azide.

a) Atom 1 has 35 protons and 45 neutrons, which means it is the element bromine (Br). Atom 2 has 12 protons and 12 neutrons, which means it is the element magnesium (Mg).

A metalloid is an element that acquires both metal and nonmetal properties. Metalloids have some characteristics of metals, such as being good conductors of electricity, while also having some nonmetallic properties such as being brittle and lacking the ability to be hammered into shape. They are located along the "staircase" on the periodic table, between the metals and nonmetals, and include elements such as boron, silicon, germanium, arsenic, antimony, and tellurium. Metalloids are important in various applications such as semiconductor industry, in which silicon is the most widely used metalloid for the production of computer chips and solar cells.

b) Bromine (Br) is a nonmetal and magnesium (Mg) is a metal.

c) Magnesium (Mg) is a metal and bromine (Br) is a nonmetal, so they would form an ionic bond.

d) The compound formed between magnesium (Mg) and bromine (Br) would be named magnesium bromide.

Chemical weathering affects hillslope form by directly removing mass from hillslopes. The transformation of primary minerals to secondary minerals can also affect the hydrology, biota, and stability of hillslopes, which in turn influence sediment transport and landscape morphology. Erosion in evolving landscapes can modulate and be modulated by chemical weathering; for example, pulses of accelerated erosion can lower the residence time of hillslope materials, thereby increasing their chemical weathering rates, which in turn accelerate the incision signal.

It is important to know the affects of temperature on pressure and thereby on winds.  At high temperature, the pressure will be high and thus, the winds will pass from that area.

What is winds?

Wind is the passage of air through the atmosphere. The uneven distribution of temperature leads to the difference in pressure. The pressure gradient results in wind.

Air pass from  high pressure area to low pressure area. According to Gay- Lussacs law, at the pressure gases is directly proportional to the temperature.

Hence, as the temperature increases, pressure in that area increases, leads to air currents to the opposite direction. This will definitely affects harnessing.
