Match the layer of Earth with its characteristic.

mote1985 [20]

Answer:

Explanation:

The Asthenosphere -- drives the movement in the plates

It is a weak and flexible part of the upper mantle of the planet Earth.

It is located below the lithosphere. The depth of it is between 200 and 80 kilometers below the surface. It is usually solid but in some regions it is fluid. The temperature dictates the thickness of the Asthenosphere.

The Core -- the hottest layer of the Earth.

The inner Core of the Earth is a layer that's located in the core of it. By definition, it is a rock-hard ball that has the radius of 1,220 kilometers, making it 20% of the Earth's radius and 70% of the Moon's radius. The samples are not discovered. It is believed that it has the composition of iron-nickel infusion along with other elements. The temperature is appx. 5430 °C, which is similar to the temperature of the surface of the Sun.

Mesosphere -- contains the lower mantle

By definition, it comes from the Greek word mesos, which means '' middle ''.

It is the third layer of the Earth. It is located above the stratosphere and below the thermosphere. The higher the altitude, the lower the temperature. It ends in the coldest part of the Earth, Mesopause. And it begins at the Stratosphere.

Lithosphere -- contains the tectonic plates

By the definition, it is also a word that came from the Greek language. It comes from the word '' lithos '' which means '' rocky ''.

It is a hard, outer part of the Earth.

On the planet Earth, it is made out of the crust of the upper mantle. The rocks from the Lithosphere are elastic.

They are two types of Lithosphere -- the oceanic Lithosphere and Continental Lithosphere.

An electric drill

Lera25 [3.4K]

Answer:

Incomplete question. Complete question is: An electric drill starts from rest and rotates with a constant angular acceleration. After the drill has rotated through a certain angle, the magnitude of the centripetal acceleration of a point on the drill is twice the magnitude of the tangential acceleration. Determine the angle through which the drill rotates by this point.

The answer is : Δ θ = 1 rad

Explanation:

Ok, so the condition involves the centripetal acceleration and the tangential acceleration, so let’s start by writing expressions for each:

Ac= centripetal acceleration At= tangential acceleration

Ac = V² / r At = r α

Because we have to determine the angle ultimately, therefore we should convert the linear velocity into angular velocity in the expression for centripetal acceleration

V = r ω

Ac = (r ω)² / r = r² ω² / r

Ac = r ω²

now that we have expressions for the centripetal and tangential acceleration, we can write an equation that expresses the condition given: The magnitude of the centripetal acceleration is twice the magnitude of the tangential acceleration.

Ac = 2 At

That is,

r ω² = 2 r α

it is equivalent to;

ω² = 2 α

now we have the relation between angular speed and angular acceleration, but we also need to determine the angular displacement as well. Therefore choose a kinematics equation that doesn’t involve time because time is not mentioned in the question. Thus,

ω² – ω°² = 2 α Δ θ

such that ω° = 0

and ω² = 2 α

therefore;

2 α - 0 = 2 α Δ θ

2 α = 2 α Δ θ

So the angle will be : Δ θ = 1 rad

If two light waves are coherent a) their amplitudes are the same their phase difference is constant their frequencies are the sa

Aleonysh [2.5K]

Answer:

a) their amplitudes are the same their phase difference is constant their frequencies are the same

Explanation:

Coherent waves are the waves that have constant phase difference, equal frequency, amplitude and waveform.

Frequency denotes the number of cycles a wave completes in one second.

Amplitude is the maximum height that the wave reaches.

Waveform is the two dimensional representation of a wave in graphical form.

What is the speed of a wave with a frequency of 100 hz and a wave length of .5 m?

____ [38]

Answer:

Explanation:

There are 2 ways to help with this. Explain the details, which are fairly simple in this topic, or give the formula. My hope is that an explanation will last longer than memorizing the formula. I give you both.

If a wave has frequency, f, of 3 Hz, its period, T, is

1

3

s

. The wavelength,

λ

, is 5 meters. That means that in the time of one period, the wave travels 5 m.

In general,

S

p

e

d

=

distance

time

In applying this general definition of speed

↑

to a wave, we have

speed of the wave

=

wavelength

period

Note: we generally use v for speed of a wave. Using the variable names, then that last formula is written

v

=

λ

T

Since

T

=

1

f

, we can also say that

v

=

λ

⋅

f

So, using that last formula

v

=

5

m

s

Note: the unit Hz is equivalent to what it was called 100 years ago,

cycles

second

(

also cps

)

. Cycles is not a true unit, so the Hz contributed only the "per second" to the result
