what factors need to be considered when building housing on a waterway
Answer:
Flooding
Explanation:
.
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)

Answer:
spikes blood sugar quickly is something it doesn't help with
Explanation:
complex-are starches and dietary fibers. They include whole grains such as wheat, barley, bulgar, rye, millet, oats, pasta, rice and legumes. Carbohydrates are our main source of energy. About 50%-60% of your plate at each meal should be composed of carbohydrates. Besides supplying you with long-lasting energy, carbohydrates also supply other nutrients such as vitamins, minerals and protein.
What elements do architects use in their design work to make buildings that encourage people's positive needs
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.

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?
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.

something stopping civilizations from
progressing beyond where we, humans,
are now?
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

The form of energy delivered to an electrical generating turbine in a geothermal facility is in the form of ________.
Geothermal energy is a product of the heat of Earth's molten interior. The form of energy delivered to an electrical generating turbine in a geothermal facility is in the form of hot water or steam.
Geothermal energy is gotten so as to generate electricity. This is done when water is injected deep underground and it then comes back as steam or hot water.This is then converted to steam so as to drive a turbine on an electric power generator. The plants makes use of steam to produce electricity.
There are three main types of energy for electricity generation. They are fossil fuels which is made up of coal, natural gas, and petroleum, and then nuclear energy, and renewable energy sources.

Technician A says a typical Manifold Absolute Pressure (MAP) sensor can be connected directly to the intake manifold or connected through a vacuum hose. Technician B says most modern MAP sensors do not use a flexible silicon chip within a chamber anymore. Who is correct
Answer:
the correct answer is: technician A
Explanation:
this answer is taken directly from the book
One method of determining engine load is through the use of a manifold absolute pressure (MAP) sensor. The MAP sensor can be either directly bolted to the intake manifold or connected through a vacuum hose.
Most modern MAP sensors use a type of flexible silicon chip within a sealed chamber; the chip changes resistance when manifold pressure flexes the chip.
