Answer:
Brittle materials:
Brittle materials are those material which does not shows any indication before failure.It means that they break suddenly without showing any indication.These materials have zero ductility.
Ex :
1.Glass is the very common example for brittle material and in our house we can easily see that when ever glass fall on the floor it breaks in very small pieces.
2. Metal objects are made from metal they behave as brittle like cast iron.
3. The another familiar example in our house for brittle material is dry clay.
Ductile materials:
Ductile materials which shows a indication before fracture.It have a range ,within this range they did not fail.The ability of material to draw into wires is known as ductility of that materials.
Ex :Those object are made from carbon steel,gold,silver etc.
Elastic deformation :
To regain the original shape after removal of load is known as elastic deformation.
Ex: The familiar example of elastic deformation is rubber band ,when we apply a force on the rubber band then it goes under the deformation but after removal the load come back on the original position.
I can't answer your question until you give me the answer choices.
Isosceles I’m pretty sure but idk
Answer:
The regions that have negative demographic trends and the ones where religion has big political power are the ones where there are policies for expansion of the population.
Explanation:
When it comes to population policies, the world can be divided into two groups, one being the one that has policies to stop the population growth and the other that has policies to expand its population. Generally speaking, the Western countries and the Muslim countries are the ones that promote the expansion of their populations, though the reasons are different.
The Western countries face very low birthrates and aging populations, so they have such policies in order to experience a decline of their populations and to have enough labor force for their economies. The Muslim countries, on the other hand, are countries where the religious authorities have big political power, and as it has always been the case in such situations, there is policies in place for expansion of the population so that the religion has more power through more followers, and maybe even expand by attacking other countries in the future.
