The eastern margin is a convergent boundary subduction zone under the South American Plate and the Andes Mountains, forming the Peru–Chile Trench. The southern side is a divergent boundary with the Antarctic Plate, the Chile Rise, where seafloor spreading permits magma to rise.

Explanation:

The south-eastern side of the Pacific plate is a divergent boundary (the plates are pulled, and not pushed, apart) with the Nazca Plate forming the East Pacific Rise.

The East Pacific Rise is part of the circumglobal system of active volcanic ridges, all of which define the position of diverging plates where new crust is being created. These ridges represent the locus of global shallow-water earthquakes.

Electrically neutral objects cannot exert an electrical force on each other, but they can exert a gravitational force on each ot

Olenka [21]

The correct answer is
A) true

In fact, the electrical force can be present only if the two objects have a net charge different from zero, because the electrical force is proportional to the value of the charges:
$F_e = k_e \frac{Q_1 Q_2}{r^2}$
so, if they are neutral they cannot exert an electrical force between each other, because their charge Q is zero.

Viceversa, the gravitational force is always present when the objects have masses, since the force is proportional to the value of the masses:
$F_g = G \frac{m_1 m_2}{r^2}$
so, even if the two objetcs are neutral, if they have mass, they exert a gravitational force to each other.

(ii) two locomotives approach each other on parallel tracks. each has a speed of 155 km/h with respect to the ground. if they ar

IgorLugansk [536]

You have to find an equation that would relate the two motions of the locomotives. When they meet at a certain point after being 8.5 km apart initially, then that means that their individual distances traveled is equal to 8.5 The solution is as follows:

Distance = speed*time
Total distace = 8.5 = 155t + 155t
Solving for t,
t = 0.027 hour or 98.71 seconds

The fact that light travels at 300,000 km/s is a consequence of Energy Conservation
The particle that move with that kind of speed creates energy way faster than the particle that don't. Which means that it would require less effort to produce the energy,

TiliK225 [7]

Answer:

v = 2,99913 10⁸ m / s

Explanation:

The velocity of propagation of a wave is

v = λ f

in the case of an electromagnetic wave in a vacuum the speed that speed of light

v = c

When the wave reaches a material medium, it is transmitted through a resonant type process, whereby the molecules of the medium vibrate at the same frequency as the wave, as the speed of the wave decreases the only way that they remain the relationship is that the donut length changes in the material medium

λ = λ₀ / n

where n is the index of refraction of the material medium.

Therefore the expression is

v = $\frac{\lambda_o}{n} f$
