What is the difference between bare and
shielded electrodes
Answer:
shielded electrodes give metal smotth and clean welds and bare electrodes reduces spattering.
Explanation:
Shielded electrodes minimize sulfur, oxides, and other types of impurities within the base metal to give regular, smooth, and clean welds while bare electrodes, makes welding more manageable and reduces spattering

How do we infer that there is
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
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.

Cooling water available at 10°C is used to condense steam at 30°C in the condenser of a power plant at a rate of 0.60 kg/s by circulating the cooling water through a bank of 7-m-long 1.2-cm-internal-diameter thin copper tubes. Water enters the tubes at a mean velocity of 4 m/s and leaves at a temperature of 24°C. The tubes are nearly isothermal at 30°C. Determine the average heat transfer coefficient between the water, the tubes, and the number of tubes needed to achieve the indicated heat transfer rate in the condenser.

How to handle or hold sharp edged tools in welding
Answer: I got you bestie :)
When walking with a sharp tool, the tool should be carried with the blade down and away from the body. When climbing with a sharp tool, tool belts, or buckets with hand lines should be used so workers can have both hands to grip the ladder.

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.
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.
