Concrete has a higher specific heat than does soil. Use this fact to explain (partially) why a city has a higher average temperature than the surrounding countryside.

Answers

Answer:

Since concrete has higher specific heat, it will absorb more heat and the temperatures will rise in proportion. The large amount of energy stored in concrete during the day as the sun falls on it is released at night, resulting in an higher average evening temperature than the countryside. The cool air in the surrounding countryside exerts a buoyant force on the warmer air in the city, pushing it upward and moving into the city in the process. Thus, evening breezes tend to blow from country to city.

Explanation:

The city has a higher average temperature than the surrounding countryside as most of the cities are made up of concrete designs one of the things which absorb a lot of heat.

What is soil?

Soil contains lots of minerals as well as microorganisms. One can grow crops or vegetation on the soil. This is made up of various types of sand and granules that can be present.

Concrete absorbs more heat because of its high surface heat, which causes temperatures to rise proportionately. Asphalt absorbs a lot of energy generated by the sun each day and releases it at night, giving cities a warmer average nighttime weather than rural.

The heated air in the city is propelled higher and toward the city by the density of water of the cooler in the nearby countryside. As a result, evening gusts frequently travel between rural to city.

Answers

Answer:

shielded electrodes give metal smotth and clean welds and bare electrodes reduces spattering.

Explanation:

if we model the vibrating system as a mass on a spring, what is the mass necessary to achieve the desired resonant frequency when the tip is not interacting with the surface?

Answers

Answer:

2.5 micrograms

Explanation:

The frequency of a vibrating body reduces with increasing mass, but increases with increasing tension.

What is the relation of resonant frequency with mass?

For a spring-mass system, the relationship between frequency and mass can be expressed as follows: as mass increases, frequency decreases; as mass decreases, frequency increases.

The frequency in this case is f, and the mass is m. The relationship between mass and frequency is therefore inverse.

Precession frequency drops when mass is doubled, since angular momentum also doubles at this point. As the radius grows, the angular momentum increases and the precession frequency decreases.

Mass and stiffness are two well-known factors that affect an object's resonance frequency.

While stiffness limits low-frequency transmission because less elastic, or stiff, materials vibrate at higher frequencies, mass limits high-frequency transmission because larger objects vibrate at lower frequencies.

Therefore, The resonant frequency should rise as mass decreases.

When building housing on a waterway one must always consider the factor of Flooding and its repercussions.

What is a Flood?

A flood occurs when there is an excessive amount of water and it covers normally dry areas. The word can also refer to the tide's influx when used in the sense of "flowing water." Floods are a topic of research in the hydrology field and are very important to the fields of agriculture, civil engineering, and public health.

Floods have serious societal repercussions for both communities and people. As most people are well aware, flooding has a number of direct effects, including the loss of life, destruction of property, loss of crops and livestock, and worsening of health due to waterborne infections.

Stream gauges that are put in bodies of water close to inhabited areas are used to measure floods. The National Weather Service receives all data collected by them before it is sent to the United States Geological Survey (USGS), which erected and operates them (NWS)

What elements do architects use in their design work to make buildings that encourage people's positive needs

Answers

Answer:

Form/Formal Elements

Explanation:

This should be the correct answer i dont know if im fully correct.

These components are arranged in the order in which a single point becomes a one-dimensional line, a line becomes a two-dimensional plane, and eventually a plane becomes a three-dimensional volume.

What element  do architects use in their design work?

Points, lines, planes, and volumes make up the main components of form, each one developing from the last.

A line is an extension of a point, which is a location in space. A line's extension is referred to as a surface or plan. A plane is stretched into a volume.

In all eras of society, the hearth served as the sacred center around which structure and order were given. It is the foundational and most significant part of architecture.

Therefore, Form/Formal Elements do architects use in their design work to make buildings that encourage people's positive needs.

How do we infer that there is
something stopping civilizations from
progressing beyond where we, humans,
are now?

Answers

Answer:

Not too far removed from Collingwood’s concern with the elimination of physical and moral force via social civilization are accounts of civilized society concerned with the management of violence, if only by removing it from the public sphere. Such a concern is extended in Zygmunt Bauman’s account of civilization to the more general issue of producing readily governable subjects. The “concept of civilization,” he argues, “entered learned discourse in the West as the name of a conscious proselytising crusade waged by men of knowledge and aimed at extirpating the vestiges of wild cultures” (1987, 93).

This proselytizing crusade in the name of civilization is worth considering further. Its rationale is not too difficult to determine when one considers Starobinski’s (1993, 31) assertion: “Taken as a value, civilization constitutes a political and moral norm. It is the criterion against which barbarity, or non-civilization, is judged and condemned.” A similar sort of argument is made by Pagden (1988, 33), who states that civilization “describes a state, social, political, cultural, aesthetic—even moral and physical—which is held to be the optimum condition for all mankind, and this involves the implicit claim that only the civilized can know what it is to be civilized.” It is out of this implicit claim and the judgments passed in its name that the notion of the “burden of civilization” was born. And this, many have argued, is one of the less desirable aspects and outcomes of the idea of civilization
