What are the benefits and drawbacks to the different kinds of compasses that have been invented?

Answers

Answer 1

Answer:Disadvantages

It is less precise compared to other advanced methods of surveying.

It is easily subjected to various errors such as errors adjoining magnetic meridian, local attraction etc.

Imperfect sighting of the ranging rods and inaccurate leveling also causes error.

ADVANTAGES: Does not require any electrical power to function (except for night illumination), therefore is not affected by the loss of power. Tends to be more stable than a fluxgate compass. Usually, the bigger the compass card diameter on a magnetic compass, the more stable, (and also the easier to read)

Answer 2
There are different kinds of compasses that are differently built and have different purposes. We will mention some of them here:

Two main types of the compass are magnetic compass and gyro compass. First one has a magnetic element (needle or a card) that aligns itself with magnetic lines of Earth's magnetic field to point to the magnetic poles of the Earth. Gyro compass has a rapidly spinning wheel whose rotation interacts with the rotation of the earth until its axis of rotation is parallel with the Earth's and points to the Earth's rotational poles. This compass points to the true poles of the Earth. Liquid compass - has a magnetized needle or card immersed in fluid. This method lessens excessive swing and wobble and improves readability while reducing wear.

Marine compass or a card compass - This type of compass has a needle that is fixed and a compass card that is mounted in fluid and rotates according to orientation. It is used on boats because the moving card absorbs much of the motion of a boat which makes it easier to read than a needle compass. Prismatic compass or lensatic compass - has a glass prism or a lens and a lid that has a hairline. These are used for lining up with an object whose bearing is sought. It also has compass card which rotates in the base. When the compass card stops, the required bearing is read off through the prisms or lens. Some of them have liquid as a damping mechanism while other use electromagnetic induction for the same purpose. Some also have tritium and a combination of phosphors which help to read of the compass in the dark.

Base plate compass or Orienteering compass - is a liquid filled compass placed on the rectangular base made of transparent plastic so a map can be read through it. It often has a magnifying lens for map reading, some sort of light for low light conditions and a ruler. It is often used for plotting.

Answers

Answer:

Tectonismo e intemperismo.

Explanation:

O relevo terrestre é um sistema que esta em constante transformação e que se apresenta de forma muito dinamica e harmoniosa. Essas transformções que o relevo é submetido são provocadas por processos que acontecem tanto na superficie terrestre quando no interior, sendo chamados agentes modeladores internos e externos.

Dentro os modeladores internos, que são os que ocorrem no interior da terrapodemos citar o tectonismo, os abalos sísmicos e o vulcanismo. Dentre os modeladores externos, que acontecem na superficie da terra, podemos citar o intemperismo e a erosão.

IN WHICH ERA BACTERA WAS ORIGINATED?
PLEASE HELP I AM IN TROUBLE...

Answers

Explanation:

Bacteria have existed from very early in the history of life on Earth. Bacteria fossils discovered in rocks date from at least the Devonian Period (419.2 million to 358.9 million years ago), and there are convincing arguments that bacteria have been present since early Precambrian time, about 3.5 billion years ago. Bacteria were widespread on Earth at least since the latter part of the Paleoproterozoic, roughly 1.8 billion years ago, when oxygen appeared in the atmosphere as a result of the action of the cyanobacteria. Bacteria have thus had plenty of time to adapt to their environments and to have given rise to numerous descendant forms.

The nature of the original predecessor involved in the origin of life is subject to considerable speculation. It has been suggested that the original cell might have used RNA as its genetic material, since investigations have shown that RNA molecules can have numerous catalytic functions. The Bacteria and Archaea diverged from their common precursor very early in this time period. The two types of prokaryotes tend to inhabit different types of environments and give rise to new species at different rates. Many Archaea prefer high-temperature niches. One major branch of the archaeal tree consists only of thermophilic species, and many of the methanogens in another major branch can grow at high temperatures. In contrast, no major eubacterial branch consists solely of thermophiles. Both Bacteria and Archaea contain members that are able to grow at very high temperatures, as well as other species that are able to grow at low temperatures. Another prominent difference is that bacteria have widely adapted to aerobic conditions, whereas many archaea are obligate anaerobes. No archaea are obligately photosynthetic. Perhaps the archaea are a more primitive type of organism with an impaired genetic response to changing environmental conditions. A limited ability to adapt to new situations could restrict the archaea to harsh environments, where there is less competition from other life-forms.

inches is that per month?
2. The canal carried about 80 gallons of water per minute from the spring. How
many gallons would the canal carry in 10 minutes?

Answers

Answer:

1. 1 year = 12 months

that means there is 72 inches of rainfall every 12 months. 72/12 = 6 inches per month

2. 80 gallons per minute means you just have to multiply 80 by 10. 80 x 10 = 800 gallons in 10 minutes

It appears that religion has been around in one form or another for most of human history. Do you think it is getting stronger, dying out, or staying about at the same level of importance? Why?

Answers

I think this question is very dependent on who you ask personally I dont think its dying out but I definitely think it's less of a key aspect of society then it ever was. I think this because being apart of the the younger generation we have been taught to question everything, and religion doesn't always have the answers nor does it line up with alot of morals that people have.

What is migration?

The long-term relocation of a person or group is known as human migration. Many categories can be used to categorize migrations. First, we can distinguish between domestic and international migration.

In contrast to international migration, domestic travel is the movement of people and families within a single country. Migration can also be forced or voluntary, second.

Whether internal or external, the majority of voluntary movement is made in search of better job or housing opportunities.

Forced migrations often consist of people who have been forcibly moved as slaves or prisoners, or who have been ejected by governments during war or other political upheavals.

Between these two categories are the voluntary migrations of refugees fleeing conflict, famine, or natural disasters. Thus, the Europe has hight migration rate.

The big, deadly explosions are caused by water vapor, rich in CO2 that bubbles out, deeper down at much higher pressure. When CO2 starts appearing, a volcanic eruption event is on its way.

What is volcanic eruption?

A volcano is a hole in the surface of the earth through which gases, volcanic ash, and hot, liquid, or semi-liquid rock can escape. They often develop when tectonic plates collide or diverge, although volcanic hotspots can also cause them to form in the midst of plates. A volcanic eruption occurs when a volcano releases gas and/or lava, occasionally violently.

Many advantages of volcanoes for the environment include fertile soils, hydrothermal energy, and priceless minerals. Yet they also provide a number of risks, including mudslides, landslides, lava flows, pyroclastic flows, volcanic ash, gases, and lahars (mudflows) (fast-moving currents of hot gas). Volcanic eruptions frequently result in population dislocation, food shortages, and the potential for fatalities.
