So the moon does rotate. Why, then, do we see only one face of the moon? One side of the moon always faces Earth because of what's called synchronous rotation. That is, the moon rotates, or spins on its axis, in the same length of time it takes to orbit Earth.

When we rewrite the given in a simpler unit we have 7.9 ms-1.

By looking at the units of the quantities involved, dimensional analysis is a technique for determining whether a physical equation or formula is right. The essential tenet of dimensional analysis is that the quantities being multiplied or divided in the equation must have units that are equal to the units of the final result.

We know that we have to apply the principles that apply to dimensional analysis in the question and we have that;

m^2.s/m.s^2

= ms-1

Explanation:

Earth's core is the most dense layer and it consists of the outer core and the inner core.

In the given graph, the Evolved Population is showing disruptive selection. Hence, the correct option is A. Disruptive selection.

Stabilizing selection is a form of natural selection where individuals with average phenotypes are more likely to survive and reproduce their number. In this selection, the population tends to maintain a stable phenotype. As shown in the graph, the population is maximum for the population having a moderate length of neck.

Disruptive selection is a type of natural selection where extreme phenotypes are preferred over average phenotypes, leading to an increase in genetic variation and the population becoming more diverse. In this type of selection, the population diverges into two or more distinct phenotypic groups. As shown in the graph, two ranges of the population are favored for having traits for extreme lengths of the neck.

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.

Answer:

Plasma is a substance which is extremely hot. The heat present in plasma, a gas, is provided as energy in order to split electrons and protons apart. Therefore, ions and electrons are formed as products.

Explanation:

The state of matter  of the substance where in the electrons and protons are separated from the atom is plasma.

Matter in chemistry, is defined as any kind of substance that has mass and occupies space that means it has volume . The matter is composed up of atoms which may or not be of same type.

Atoms are further made up of sub atomic particles which are the protons ,neutrons and the electrons .The matter can exist in various states such as solids, liquids and gases depending on the conditions of temperature and pressure.

The states of matter are inter convertible into each other by changing the parameters of temperature and pressure.Matter can neither be created nor destroyed which is given by the law of conservation of matter.

In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same.

Answer:

d

Explanation:

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.

e) The formula for magnesium bromide is MgBr2, since magnesium (Mg) has a +2 charge and bromine (Br) has a -1 charge.

Answer:

conduction is the transfer of heat between two objects that are next to each other and in direct physical contact, or touching . It is caused by a temperature difference between the objects. Conduction is one way that heat is transferred from Earth's surface to air. In nature, heat always moves from a warmer object to a cooler object. When air molecules touch the warm ground or water on the surface, heat is conducted from the ground or water to the air molecules, heating them up.
