D. Rock type
Explanation:
The major factor that influences the strength of rocks is the rock type.
Different rock types are known to have their own relative strength.
Based on their strength, rocks are classified into hard and soft rocks.
Soft rock types are dominated by sedimentary rock. Sedimentary rocks are formed by accumulation and deposition of sediments. They are often layered.
Metamorphic and igneous rocks are usually classified as hard rocks. These rocks forms under very high temperature and pressure conditions.
In engineering applications, the soft rocks not desired for construction purposes although they have their own unique material functions.
Hard rocks are used for heavy duty and durable constructions like dams and bridges.

Answer:
d). It is easier to make a large reflecting telescope than a large refracting telescope.
f). A reflector can collect more light than a refractor.
Explanation:
A telescope is a device that is used to observe distant objects by the use of lenses and mirrors. It is also used to observe different distant objects by their reflection, absorption, emission or the reflection of the electromagnetic radiations.
Most of the professional telescopes are reflectors because :
1. The reflected telescope is able to receive more of the light when it reflects all the light falling on surface. And it is easier for making a large telescope rather then making large lenses for the refracting telescope. So it is easier to make large reflecting telescope than a large refracting telescope.
2. A reflected telescope receives all the wavelength of the light and it reflects all the light falling on the surfaces where it is refracted telescope that contains lenses cannot absorbs all the light and causes the chromatic aberration.

What they need is a strong republican form of government with a true balance of power between the executive, legislative and judicial branches and a strong rule of law. ... It would be better for them to have military dictatorships than to have the majority persecute and slaughter the minority as democracy would allow them to do</span>
<h2>Answer:</h2>
Balanced forces/Resultant force/ Newton's first law/law of inertia.
<h3>Explanation:</h3><h3>Balanced forces/Resultant force/ Newton's first law/law of inertia:</h3>
It says that each article will remain in its state of rest or similar motion in a straight line except a resultant force works on it. It is known as the law of inertia.
The inertia of the body is the hesitation of the target to alter its state of peace or movement.
The inertia of an article depends on its size. The greater the body, the greater the inertia. It shows it is difficult to start moving, stop, slow down, speed up or change direction. Force is required to overcome inertia.
Answer:
Humans require water for survival, so they tend to settle near areas with access to large amounts of water. Rainfall and water bodies such as rivers and lakes provide humans with clean water for drinking, cleaning, agriculture and recreational activities. Pollution of water supplies and population growth depletes aquifers leading to competition and waterborne diseases, especially in developing countries.
Climate patterns around the world influence human settlements. They live in conditions that favor their lifestyles and alter their clothing and housing in accordance with climate. In addition, extreme weather leads to sparsely populated areas and limit agricultural practices; for example, harsh and cold weather favor plants that can adapt to that environment.
Land formations such as mountains and hills shape transportation routes and networks, while the movement of tectonic plates on the Earth's surface sometimes causes hazards like earthquakes that destroy habitats, displace humans and affect the availability of water.
Fertile soil carries out numerous functions such as supporting life, recycling nutrients, regulating water and providing structural support for buildings. Humans extract minerals and perform recreational activities on the soil. Infertility creates deserts and leads to the migration of settlements.
A balanced ecosystem relates to better agricultural produce and less air pollution. Provision of food, safe water and clean air improves the well-being of living organisms.
