How can a volcano develop in the middle of a tectonic plate?

Answers

Answer:

Volcanoes that form away from plate boundaries are created by hotspots. A hotspot is an area in the mantle that is believed to be somewhat hotter than the surrounding material. The rising magma from the hotspot can push its way through the crust and burst out at the surface, forming a volcano.

Explanation:

Volcanoes can form in subduction zones, which are regions where tectonic plates are interacting one and plate is sinking beneath the other.

Essay about how volcanoes form.

A volcano is a hill or mountain in the shape of a cone that is erected around a fissure in the surface of the earth thru which heated gases, rock fragments, and lava are released. A conical mass grows around the conduit as the solid fragments gather there, becoming progressively larger until it reaches the size of a gigantic volcanic mountain.

Explain what a volcano is.

A volcano is an aperture or vent through which magma, tephra (small rocks), or steam are released onto the the planet's surface. Days, weeks, or even years might pass between outbursts of volcanoes.

1. A Baltimore passenger train traveled 80 meters in 15 seconds. What was the average speed
of the train?
Show your work ! PLEASEEEE HELPPP !!

Answers

Answer:

45

Explanation:

The average speed of the train was 5.33  meter/second.

What is speed?

Speed is distance travelled by the object per unit time. Due to having no direction and only having magnitude, speed is a scalar quantity With SI unit meter/second.

Given parameters:

Distance travelled by the train is: d = 80 meters.

Time  taken by the train: t = 15 seconds.

Hence,  the average speed of the train =

total distance travelled/total time taken

= 80 meters/ 15 seconds.

= 5.33  meter/second.

What is the effort and load arm?

The lever has two “arms”:

The load arm is the portion of the lever directly connected to the load.

The effort arm is the portion of the lever to which we apply the effort, or input force.

The formula of the mechanical advantage(MA) of a lever is given as

MA = load/effort.

Given,

load = 2kg , effort = 30cm

MA = [tex]\frac{2}{30}[/tex] = [tex]\frac{1}{15}[/tex]

MA  = 0.06 cm

Explanation:

Since there are 1000 meters in a kilometer, divide 400 meters by 4, and 48.42 by 4. Then you get 100 meters equals 12.105 seconds. Multiply that by ten, and you get 121.05 seconds

The three main types of nuclear radiation are alpha, beta, and gamma
Which of the following lists these types of radiation from highest penetrating power to lowest penetrating power?
beta, alpha, gamma
beta, gamma, alpha
ОООО
O gamma, beta, alpha
O alpha, gamma, beta

Answers

Answer:

Gamma, beta, alpha

Explanation:

Gamma rays have the shortest wavelengths of all electromagnetic radiation, has the greatest penetrating power. Gamma rays can pass completely through the human body; as they pass through, they can cause ionizations that damage tissue and DNA. Then Beta particles are more penetrating than alpha particles, but can be stopped by a thin sheet of aluminum.

The correct order of these types of radiation from highest penetrating power to lowest penetrating power is gamma, beta, and alpha. The correct option is C.

Among gamma, beta, and alpha radiation, gamma radiation has the shortest wavelength. This is because gamma radiation consists of high-energy electromagnetic waves, similar to X-rays and light, but with even shorter wavelengths.

In terms of other properties:

Alpha radiation consists of particles called alpha particles, which are helium nuclei (two protons and two neutrons) that are emitted from the nucleus of an atom during radioactive decay. Alpha particles are relatively large and heavy, and they have a positive charge. They have a short range in air and can be stopped by a piece of paper or human skin, but they can cause significant damage to living tissue if they are inhaled or ingested.

Beta radiation consists of particles called beta particles, which are high-energy electrons or positrons that are emitted from the nucleus of an atom during radioactive decay. Beta particles are smaller and lighter than alpha particles, and they have a negative charge. They have a longer range in air than alpha particles, but they can be stopped by a thin sheet of metal or plastic.

Gamma radiation, as mentioned earlier, consists of high-energy electromagnetic waves. Gamma rays are similar to X-rays but have even higher energies and shorter wavelengths. Gamma rays have the longest range in air and require dense materials, such as lead or concrete, to stop them. Gamma radiation is the most penetrating of the three types of radiation and can cause damage to living tissue if exposure is prolonged.

Answers

Answer:

Speed is constant but velocity is changing

Explanation:

Speed is a scalar quantity, meaning magnitude only. Velocity is a vector quantity, meaning magnitude and direction. If you're moving in a circle at a constant speed, the speed is constant but the direction is constantly changing. Therefore, the speed is constant but velocity changes.

A wave in which the particles of the medium move up and down as the wave passes through is a transverse wave or a
a longitudinal wave

Answers

Answer:

transverse waves

Explanation:

this is because the definition of transverse waves is transverse waves are waves that travel perpendicular to the direction of the wave motion

however the definition of longitudinal waves is that longitudinal waves are waves that travel parallel to the direction of the wave motion.

so you can see the parallel means it forms compressions and rarefactions

but perpendicular means the particles will move up and down to the straight horizontal line, that's how lines are perpendicular right? ,

so the answer is transverse wave

Donde:

[tex]A_{o}[/tex], [tex]A_{f}[/tex] - Áreas inicial y final de la placa, medidas en metros cuadrados.

[tex]\alpha[/tex] - Coeficiente de expansión lineal, medido en [tex]\frac{1}{K}[/tex].

[tex]T_{o}[/tex], [tex]T_{f}[/tex] - Temperaturas inicial y final de la placa, medidas en Kelvin.

Use what you have learned in the reading to answer the following question. The point of a compass needle points to Earth’s north pole. The point in the compass needle has–

~the same polarity as Earth's north pole.
~the opposite polarity from Earth’s north pole.
~no polarity.
~unlimited polarity.

Answers

I would say unlimited polarity because the compass’s needle is always attracted to Earth’s north pole.

Good luck to you!

The point in the compass needle has the opposite polarity from Earth’s north pole. The correct option is B.

What is a compass needle?

The compass needle A magnetized pointer within a compass that can freely align with the Earth's magnetic field.

The magnetic needle is the most important part of the compass. It swings around the compass as you move, but the red end always points north and the white (or sometimes black) end always points south.

If you mean the geographical North Pole, the needle would point south because that is the only way to get there; more specifically, it would point south along the 112.4 degrees west longitude meridian towards the magnetic north pole at 82 degrees north, where compasses point.

Thus, the correct option is B.

Since the forces are only in the x-direction, you could just add the two forces. The West is to the left, so it would be -25N with the negative sign indicating direction. The East is to the right, so that would be +50N.

50 + (-25) = 25N to the right or the positive i-hat direction
