The many volcanoes located along the edge of the Pacific Ocean make up the Ring of Fire. How does subduction play a role in the volcanic activity in the Ring of Fire? Make a full paragraph!

Answers

Hello!

Subduction volcanism occurs where two plates are converging on one another. One plate containing oceanic lithospehe descends beneath the adjacent plate, consuming the oceanic lithosphere into the earth's mantle.

I really hope this helped you! :)

Answer:

When two plates collides of varying densities, one tends to subduct introducing volcanic material to the earth surface.  

Explanation:

The ring of fire is a geographical area where seismic and volcanic activities are prevalent. This region extend around the edge of the pacific plates and including smaller plates like the Juan de Faca plate, coccus plate and the Philippine plate .  The ring of fire is a place known for earthquake and volcanism due to the active plate boundary.

The plate boundaries around the rings of fire are known for subduction activities.

Usually, in a convergence boundary where continental crust collides with oceanic crust the more dense oceanic crust tends to subduct. The continental crust is less dense and possess more buoyancy. The less dense and buoyant nature of the continental crust will cause it to override the oceanic crust.

Generally, when oceanic crust and continental crust collides the oceanic crust subduct reaching the aesthenosphere area, Aesthenosphere material like magma are introduced to the earth surface through the subduction zone. The magma may creep through cracks and fissures or erupt to the earth surface. The subduction zone form trenches which is a prerequisite for  creating mountains, volcanisms and earthquakes.

What occurs when an object vibrates in response to sound waves of a certain frequency?

Answers

i believe its vibration or my teacher taught me wrong

answer: resonance

Explanation: APHEX

What has to be true about mass if a small object (like a metal ball) has a high density? A: The mass has to be high compared to the volume. B: The mass has to be low compared to the volume. C: The mass is not related to the density. D: The mass would be determined by throwing the ball in water.

Answers

Since density is equal to mass divided by volume, we can determine the relationship between mass, density, and volume. Therefore, we can automatically know that the answer must either be A or B, since this information is determinable. The prompt lists the object as small. Therefore, we know that density is high, but volume is low. Let's examine the equation (D = M/V), where d = density, m = mass, and v = volume. In order for any number to be divided by a smaller number and have the end result be a higher number, the numerator (i.e. mass) must be bigger than the denominator (i.e. volume). We can also see that this is true by substituting in somewhat random numbers for d, m, and v. D = M / V 5 = 10 / 2 10 > 2 M > V In conclusion, your answer is D.

Answer:

the mass must be high compared to the volume

a car moving 12 m/s stops in 3 seconds vf=

Answers

Your question is not complete
For this I can answer only this
That it can stop in 3 seconds

Answer:

The question seems to be looking for vf, which may be the final velocity.

We know that the car stops, so the car is at rest, this means that the final velocity is equal to zero.

vf = 0 m/s

Now, we also can find the acceleration, the velocity equation can be written as:

v(t) = a*t + 12m/s

We know that in 3 seconds the car stops, so we have:

v(3s) = 0 = a*3s + 12m/s

a= -12m/s*(1/3s) = -4m/s^2

So in those 3 seconds where the car is stoping, the acceleration of the car is -4m/s^2, and the velocity of the car in those 3 seconds can be described by the equation:

v(t) = -4m/s^2*t + 12m/s

By definition, Momentum = Mass x Velocity.

Let us examine the given statements, and decide whether the impulse of the momentum is either LOWERED, INCREASED, or UNCHANGED.
 
Case 1: A boxer turns his head while being punched.
By turning his head away from the incoming punch, the boxer lowers the
velocity with which the punch is delivered.
Answer: LOWERED

Case 2: A truck smashes into a two-layered retaining wall.
Neither the mass nor the velocity of the truck changes before impact.
Answer: UNCHANGED

Case 3: Mass is removed from a ship before it collides with an iceberg.
By removing mass from the ship, the momentum is lowered.
Answer: LOWERED

Case 4: A sugar-glider slows down in mid-air before hitting the ground.
By lowering the velocity, momentum is lowered.

The New York Wheel is the world's largest Ferris wheel. It's 183 meters in diameter and rotates once every 37.3 min.
Find the magnitude of the average acceleration at the wheel's rim, over a 8.60-min interval.

Answers

The radius of the Ferris wheel is r = 83/2 = 91.5 m.

The angular velocity is
ω = (2π rad)/(37.3*60 s) = 2.8075 rad/s
The tangential velocity is
v = rω = 0.2569 m/s

The arc length traveled in 8.6 min (= 8.6*60 s = 516 s) is
s = (91.5 m)*(2.8075 rad/s)*(516 s) = 132.553 m
The central angle swept is
θ = 132.553/91.5 = 1.4487 rad

From the vector diagram, the change in velocity is (from the Law of Cosines)
Δv² = v²(1 - 2 cosФ)
where Ф = Π - 1.4487 = 1.6929 rad
Δv² = 0.2569²[1 - 2*(-0.1218)] = 0.0821
Δv = 0.2865 m/s

The acceleration is
a₁ = (0.2865 m/s)/(516 s) = 5.6 x 10⁻⁴ m/s²

The actual centripetal acceleration is directed toward the center of the wheel, and its value is
a = v²/r = 0.2569²/91.5 = 7.2 x 10⁻⁴ m/s²

Answer: 
a = 7.2 x 10⁻⁴ m/s², the centripetal acceleration acting toward the center of the wheel.
The magnitude of a₁ is 5.6 x 10⁻⁴ m/s², but it is not directed toward the center of the wheel.

The question that could be best answered using scientific inquiry about the discovery of the Earth revolving around the sun would be: Give four ways to demonstrate that Earth is spherical.

Measure the Earth's curvature using a long-distance view, such as observing a ship disappearing over the horizon.Conduct experiments with gravity, such as observing the shape of water in a container or using a plumb line to measure verticality.Utilize satellite imagery or photos taken from space to show the Earth's spherical shape.Observe the change in constellations as you move away from the equator, which can only be explained by Earth's sphericity.

a brick dropped from 78m high scaffold. what is the velocity as the brick hits the pavement? show work.

Answers

39.09987212 m/s There are a couple of ways to solve this problem. We can use the equation for the distance an object moves under a constant acceleration of 9.8 m/s^2, or we can calculate the kinetic energy an object will have after falling 78 meters and from there calculate the velocity. Let's first use the constant acceleration formula: d = 0.5 AT^2 78 m = 0.5 * 9.8 m/s^2 * T^2 78 m = 4.9 m/s^2 * T^2 15.91836735 s^2 = T^2 3.98978287 = T So we now know it takes 3.98978287 second for the brick to hit the ground. And at an acceleration of 9.8 m/s^2 we get: 3.98978287 s * 9.8 m/s^2 = 39.09987212 m/s Now let's try using the energy method. I will assume that the mass of the brick is 1 kg, but any non-zero value will do. So 78 m * 9.8 m/s^2 * 1 kg = 764.4 kg*m^2/s^2 And kinetic energy is expressed as KE = 0.5 mv^2 So 764.4 kg*m^2/s^2 = 0.5 1 kg * v^2 764.4 kg*m^2/s^2 = 0.5 kg * v^2 1528.8 m^2/s^2 = v^2 39.09987212 m/s = v So the determine how long it takes and multiply by the acceleration method gives 39.09987212 m/s. And the use the energy to determine the velocity gives 39.09987212 m/s. So it doesn't matter which of the two methods you use. But, personally, I think the energy method is simpler, although the time method is more direct.

Answer:

39.09987212m/s
