Answer:

The atmosphere and Earth's interior are layered by density. The differentiation between these layers is due to processes that took place during the early stages of Earth's formation (ca. 4.5 billion years ago). At this time, melting would have caused denser substances to sink toward the center while less-dense materials would have migrated to the crust.

Gravity pulls more strongly on denser materials so denser materials are at the center of things. The lowest layer of the atmosphere is denser than the upper layer. Earth's liquid metal oure has convection, which generates the magnetic field.

Explanation:

Gravity pulls more strongly on denser materials so denser materials are at the center of things. The lowest layer of the atmosphere is denser than the upper layer. Earth's liquid metal core has convection, which generates the magnetic field.

The five physical layers are the lithosphere, asthenosphere, mesosphere, outer core, and inner core. Each layer has its own properties, composition, and characteristics that affects many of the key processes of our planet. They are, in order from the exterior to the interior – the crust, the mantle, the outer core, and the inner core.

The layers of the Earth are responsible for the formation of our continents. Earthquakes can be important because of energy (seismic energy) released. The atmosphere and Earth's interior are layered by density. Gravity pulls more strongly on denser materials so denser materials are at the center of things. Earth's core, at its center, is denser than its crust. The lowest layer of the atmosphere is denser than the upper layer.

Aircraft sometimes acquire small static charges. Suppose a supersonic jet has a 0.650 µC charge and flies due west at a speed of

Ganezh [65]

Answer : $F=2808\times 10^{-11}\ N$

Explanation :

It is given that,

Charge, $q=0.650\ \mu C=0.65\times 10^{-6}\ C$

Velocity of Aircraft, $v=540\ m/s$ (in west)

Magnetic field, $B=8 \times 10^{-5}\ T$ ( in north )

Using the relation as :

$F=q(v\times B)$

Magnetic force is ,

$F=0.65\times 10^{-6}\ C\times 540\ m/s\times 8 \times 10^{-5}\ T$

$F=2808\times 10^{-11}\ N$

Using Right hand thumb rule, the direction of force is in the plane perpendicular to the velocity and the magnetic field i.e. $-\hat{k}$ .

Which type of stress causes deformation that leads to earthquakes at converging plate boundaries?

ki77a [65]

The answer is Compressional Stress

In geology, stress is the force per unit area that is placed on a rock. ... This is called confining stress. Compression squeezes rocks together, causing rocks to fold or fracture (break). Compression is the most common stress at convergent plate boundaries.

I hope this helped!! Have a great day :D

A truck drives with a constant linear speed v_iv i v, start subscript, i, end subscript down a road with two curves. The first

Alex

Answer:

Explanation:

Centripetal acceleration is given by

$a = \dfrac{v^2}{r}$

where v is the linear velocity and r is the radius of the curve.

Let the centripetal acceleration on the curve of radius R be $a_1$ .

Then

$a_1 = \dfrac{v_i^2}{R}$

Let the centripetal acceleration on the curve of radius 3R be $a_2$ .

Then

$a_2 = \dfrac{v_i^2}{3R} = \dfrac{1}{3}\dfrac{v_i^2}{R} = \dfrac{1}{3}a_1$

Here, we see that the acceleration decreases by a factor of 3.

Every star is part of a constellation and is assigned a Greek letter within the constellation. Many stars still bear ancient Ara

Andru [333]

Answer:

All 88 constellations are based on figures that originated in Greek and Middle Eastern mythology. (Correct)

The α star in a constellation is usually brighter than the β star. (Correct)

All stars are part of some constellation. (Correct)

The modern constellations have English names rather than Latin like the ancient ones. (Correct)

Explanation:

Constellations were grouped by different civilizations as mean to be oriented when they were making observations of the sky (they could see as maps of certain regions). Each constellation is an arrangement of several stars in a specific figure (animals, mythological characters and objects), things that were important for that civilization.

The letter $\alpha$ is given to the brightest star in a constellation while the other letters of the Greek alphabet are assigned to the other stars that belong to that specific constellation according to their brightness. For example in the Orion constellation the brightest star is Betelgeuse so it is classified with an $\alpha$ ; $\beta$ to Rigel, the second in brightness and so on. That classification system was established by the astronomer Johann Bayer in 1603.

The modern constellations have English names, for example the constellations of Telescopium, Fornax, Sculptor, Chamaeleon, among others.

As constellations represent maps of different regions in the sky, any star will be related with them. For that reason is correct to say that all stars are part of some constellation.
