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.

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! :)

Two 3.0 μC charges lie on the x-axis, one at the origin and the other at What is the potential (relative to infinity) due to the
Airida [17]

Complete Question:

Two 3.0µC charges lie on the x-axis, one at the origin and the other at 2.0m. A third point is located at 6.0m. What is the potential at this third point relative to infinity? (The value of k is 9.0*10^9 N.m^2/C^2)

Answer:

The potential due to these charges is 11250 V

Explanation:

Potential V is given as;

V =\frac{Kq}{r}

where;

K is coulomb's constant = 9x10⁹ N.m²/C²

r is the distance of the charge

q is the magnitude of the charge

The first charge located at the origin, is 6.0 m from the third charge; the potential at this point is:

V =\frac{9X10^9 X3X10^{-6}}{6} =4500 V

The second charge located at 2.0 m, is 4.0 m from the third charge; the potential at this point is:

V =\frac{9X10^9 X3X10^{-6}}{4} =6750 V

Total potential due to this charges  = 4500 V + 6750 V = 11250 V

Which of the following scenarios will cause the current to stop flowing within a circuit?
Lelechka [254]
C is correct. Only a closed circuit can carry current, opening a switch disconnects the circuit and stops current from flowing. Remember, all current flows in loops, if you can't make a loop out of it, current can't flow, and opening a switch, assuming no other paths for current exist, will completely stop the current.

2 Newtons to the right.

3 newtons are needed to over come the friction. There are 2 left over.

So the answer is 2 newtons to the right.

Alona [7]

Answer:

7.59Ns

Explanation:

Given parameters:

Force  = 1360N

Time of contact  = 5.85 x 10⁻³s

Unknown:

Impulse  = ?

Solution:

The impulse of the ball is given as:

        Impulse  = Force x time

       Impulse  = 1360 x 5.85 x 10⁻³ = 7.59Ns

Which best describes the surface of a concave mirror? It is flat. It is textured. It curves outward. It curves inward.
Sonja [21]

The concave mirror is a spherical-shaped mirror that has an inner curved surface. Hence, option (4) is correct.

What is a concave mirror?

The concave mirrors are spherical-shaped mirrors that are painted on the outward surface. It is also known as the converging mirror, having the recessed inner reflecting surface.

  • The concave mirrors are generally used for the purpose to focus the light. For that, they might have a reflecting surface, curved inwards, and the reflection of light is limited to the single focal point.
  • The reflecting surface of the concave mirror has its vertex or midpoint lying farther away from the objects than the edges.

Thus, we can conclude that the surface of the concave mirror is curved inward. Hence, option (4) is correct.
