<h3><u>Answer;</u></h3>

Accretionary wedge

<h3><u>Explanation;</u></h3>
  • An accumulation of different sedimentary and metamorphic rocks combined with scraps of ocean crust is called<em><u> accretionary wedge.</u></em>
  • <em><u>Accretionary wedge results from the sediments that are accreted onto the subducting tectonic plate at a convergent plate boundary.</u></em>
  • At the abduction zone,<em><u> the lower plate scrapes along the bottom of the overriding plate as it enters the earth, an action which erodes material that consists of rock and sediment that then accumulate onto the overriding plate in an accretionary wedge.</u></em>

<span>Accretionary wedge. The accretionary wedge is formed from several sediments: marine sediments, but also erosional materials from volcanoes. ocean floor basalts, volcanic island masses, pelagic sediments, trench sediments and other materials transported by gravity. All these sediments are in the non-subducting tectonic plate of the Earth.</span>

The force of attraction between a -165.0 uC and +115.0 C charge is 6.00 N. What is the separation between these two charges in m
Simora [160]

Answer:

  • The distance between the charges is 5,335.026 m

Explanation:

To obtain the forces between the particles, we can use Coulomb's Law in scalar form, this is, the force between the particles will be:

F = k \frac{q_1 q_2}{d^2}

where k is Coulomb's constant, q_1 and q_2 are the charges and d is the distance between the charges.

Working a little the equation, we can take:

d^2 = k \frac{q_1 q_2}{F}

d = \sqrt{ k \frac{q_1 q_2}{F}}

And this equation will give us the distance between the charges. Taking the values of the problem

k= 9.00 \ 10^9 \frac{N \ m^2}{C^2} \\q_1 = 165.0 \mu C \\q_2 = 115.0 C\\F=- 6.00

(the force has a minus sign, as its attractive)

d = \sqrt{ 9.00 \ 10^9 \frac{N \ m^2}{C^2} \frac{(165.0 \mu C) (115.0 C)}{- 6.00 \ N}}

d = \sqrt{ 9.00 \ 10^9 \frac{N \ m^2}{C^2} \frac{(165.0 \mu C) (115.0 C)}{- 6.00 \ N}}

d = \sqrt{ 28,462,500 \ m^2}}

d = 5,335.026 m

And this is the distance between the charges.
