1. Compare: Set the Water temperature to 0 °C and click Play. Observe the water molecules.
Click Reset, set the Water temperature to 100 °C, and click Play again.
What do you notice? The water molecules are moving slightly faster at 100 °C than at 0 °C.
[Note: This difference may be too small to observe easily.]
2. Observe: Click Reset. The mean molecular speed of the water molecules is displayed
below the container. Set the Water temperature to 0 °C and Add/remove heat energy to
400 J/s. Click Play.
A. How does the mean speed of the water molecules change as they are heated?
The average speed of water molecules increases as they are heated.
B. Does the mean molecular speed change as much as the temperature as the
water heats up? Explain.
Sample answer: For each degree of temperature change, the mean molecular
speed increases by about 1 m/s. At 100 °C, the mean molecular speed is about
17% faster than at 0 °C.
3. Explain: How is temperature related to the motions of molecules?
The higher the temperature, the faster the molecules move.
4. Observe: Click Reset. Set the Water temperature to 20 °C and the Ice volume to 50 cc.
Set Add/remove heat energy to 0 J/s. Click Play. How do the molecules in the liquid
interact with the molecules in the solid?
The molecules of the liquid collide with the molecules of solid, gradually breaking the bonds
between the molecules in the solid and causing the ice to melt.

Find examples of history and politics « written » from both absolutist and relativist positions. write a paragraph

Answers

Answer:

The term ‘absolutism’ has both a moral and political connotation. In terms of morality, ‘absolutism’ refers to at least two distinct doctrines. Firstly, absolutism may refer to the claim that there exists a universally valid moral system, which applies to everyone whether they realize it or not. In this sense, absolutism is opposed to moral relativism, which denies the existence of universally applicable moral principles. Secondly, absolutism may refer to the claim that moral rules or principles do not admit any exceptions. Immanuel Kant, for instance, is an absolutist (in this sense) with respect to lying, because he held that it is never permissible to lie. This variety of absolutist need not maintain that all moral principles are absolute. Most contemporary defenders of absolutism would not hold that lying is always impermissible but may maintain this of (e.g., torture).

In terms of politics, ‘absolutism’ refers to a type of government in which the ruler’s power is absolute, that is, not subject to any legal constraints. The European monarchies, especially those of France, Spain, and Russia, between the fifteenth and eighteenth centuries provide perhaps the clearest examples of absolute rule, although forms of absolutism have existed in most parts of the world. It was not until the end of the eighteenth century that the prevalence of absolute rule in Europe began to wane.

The word ‘absolutism’ does not have an entirely uniform meaning within contemporary moral and political writings. This article outlines three central uses of the term, which may serve as an introduction to the topic.

1.

Answers

Answer:

This paragraph may help you with your questions.

Explanation:

The archduke traveled to Sarajevo in June 1914 to inspect the imperial armed forces in Bosnia and Herzegovina, annexed by Austria-Hungary in 1908. The annexation had angered Serbian nationalists, who believed the territories should be part of Serbia. A group of young nationalists hatched a plot to kill the archduke during his visit to Sarajevo, and after some missteps, 19-year-old Gavrilo Princip was able to shoot the royal couple at point-blank range, while they traveled in their official procession, killing both almost instantly.

The assassination set off a rapid chain of events, as Austria-Hungary immediately blamed the Serbian government for the attack. As large and powerful Russia supported Serbia, Austria asked for assurances that Germany would step in on its side against Russia and its allies, including France and possibly Great Britain. On July 28, Austria-Hungary declared war on Serbia, and the fragile peace between Europe’s great powers collapsed, beginning the devastating conflict now known as the First World War.

In addition, anyone who wants to know more about this subculture and how to be part of it, will find it easy to research, since it is a highly popular subculture to the point that it has already become a part of pop culture.

2. Subcultures are supported to the extent that they meet the standards established by society. This is because subcultures that do not meet these standards are often judged, devalued and suppressed.

4. Gothic has little influence on my visual identity, but it has attracted a lot of my attention in the form of arts and literature which I think has a strong influence in awakening feelings and perceptions in me.
