Which layer of the Earth contains most of the Earth's mass?A.outer core
B.crust
C.inner core
D.mantle

Answers

The mantle is the layer of the Earth that contains most of the Earth's mass. The correct option is (D).

The part of the Earth's crust that contains the majority of its mass is called the mantle. Between the crust and the outer core, it is located. The mantle is made up of hot, flowing rock known as magma and is a thick, semi-solid layer. It makes up around 84% of the entire volume of the planet and is in charge of tectonic plate movement, volcanic activity, and other geological processes that sculpt the surface. In comparison to the mantle, the outer core and inner core have substantially smaller volumes.

Hence, the mantle is the layer of the Earth that contains most of the Earth's mass. The correct option is (D).

according to the modern classification system, which list is written correctly from least specific to most specific?

Answers

As per the modern classificationsystem, the class, order, genus, species is arranged from least specific to most specific one. The correct option is C.

What is classification system?

The term classification can refer to one or more of the following: the process of classifying the resulting set of classes the classification of elements into predefined classes Classifying, in its broadestsense, is a fundamental concept and a component of almost all activities.

In 1956, Herbert FaulknerCopeland (1902-1968) proposed the four kingdom classification.

Monera, Protista, Plantae, and Animalia were the four kingdoms. He classified unicellular organisms into two groups: the Monera kingdom and the Protista kingdom.

The classificationsystem provides a wealth of information about organism characteristics. Using scientific names as a shorthand method of describing a plant or animal can thus be beneficial.

Thus, the correct option is C.

What acceleration does a 9 N force produce in a 3 kg object? Make sure to show your work. (The 4 steps)​

Answers

Answer: 3m/s^2

Explanation:

Given that:

Acceleration of object = ?

Force = 9 N

Mass of object = 3 kg

Since force is the product of the mass of an object and the acceleration by which it moves i.e Force = mass x acceleration

9N = 3kg x acceleration

Acceleration = 9N/3kg

Acceleration = 3m/s^2 (3 metres per second square)

Thus, an acceleration of 3m/s^2 is produced.

How do ants use formic acid to stay alive

"When the crazy ants were dabbed with fire ant venom, they would go off and do this ... arid soils or severe freezes, that will be too harsh for them to survive.
Invasive “crazy ants” are rapidly displacing fire ants in areasacross the southeastern US by secreting a compound that neutralizes theother’s venom.It’s the first known example of an insect having the ability to detoxify another insect’s venom, researchers say.The crazy ant invasion is the latest in a series from the southernhemisphere and, like its predecessors, will likely have dramatic effectson the region’s ecosystems. Known for their painful stings on humansand other animals, fire ants dominate most ant species by dabbing themwith powerful, usually fatal venom. A topical insecticide, the venom istwo to three times as toxic as DDT on a per weight basis.invasive filesBut when a crazy ant is smeared with the venom, it begins anelaborate detoxification procedure—it secretes formic acid from aspecialized gland at the tip of its abdomen, transfers it to its mouth,and then smears it on its body.In lab experiments, exposed crazy ants that were allowed to detoxifythemselves had a 98 percent survival rate. This chemical counter-weaponmakes crazy ants nearly invincible in skirmishes with fire ants overfood resources and nesting sites. The research is published in thejournal science express.“As this plays out, unless something new and different happens, crazyants are going to displace fire ants from much of the southeastern USand become the new ecologically dominant invasive ant species,” says EdLeBrun, a research associate with the Texas invasive species researchprogram at the Brackenridge Field Laboratory at the University of Texasat Austin.Researchers have previously reported that where crazy ants take hold,the numbers and types of arthropods—insects, spiders, centipedes, andcrustaceans—decrease, which is likely to have a ripple effect onecosystems by reducing food sources for birds, reptiles, and otheranimals. They also nest in people’s homes and damage electricalequipment.

How is scientific definition of work different from the ordinary concept of wok

Answers

Scientific definition of work is using force to move an object a distance (A=F×S where A is work m, F is force and S is distance). Work in general is a synonym for a job meaning an activity involving mental or physical effort done in order to achieve a result (get money in most cases).

Voltage difference causes charge to flow from?

Answers

Voltage difference causes charge to flow from higher potential to that of a lower potential.

What is Potential difference?

This is also known as Voltage difference and it is the difference in electric potential between two points.

V= W/Q

where v is potential difference, w is work done and q is charges.

This allows for charges to flow from higher potential to that of a lower potential.

Answer:

Voltage difference causes charge to flow from higher potential to that of a lower potential.

Explanation:

Voltage Difference:

It is work done per unit charge in moving a charge from one point to another point.

V = Voltage difference

W = Work done

Q = Charge

Then,

V = (W)/(Q)

unit : Volt or Joule/Coulomb

Flow of charge :

A free positive charge move from a region of higher potential to that of lower potential whereas a free negative charge moves from lower potential region to a higher potential.

Thus, a voltage difference is required for the flow of charge.

Direction of conventional current is from positive terminal to negative terminal.

Direction of electron is from negative to positive.
