What is likely happening at the boundary between the Nazca plate and the Pacific plate?

<span>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.</span>

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.

I hope you find this information useful and interesting! Good luck!

How is temperature related to the physical change of a substance?

WINSTONCH [101]

When you heat something of cool it down you don't change the substance you might change the why is looks, but it is still the same substance. For example you cool water to 0 degrees Celsius it turns into ice but it still is two parts hydrogen and one part oxygen H2O. Physical changes will change state and/or form but it will still be what it originally was on the molecular level. Hope that helped.

Answer:

b) a = -k / m x , c) d²x / dt² = - A w² cos (wt+Ф) , d) and e) T = 2π √m / k

h) a = - A w² cos (wt+Ф)

Explanation:

a) see free body diagram in the attachment

b) We write Newton's second law

Fe = m a

-k x = ma

a = -k / m x

c) the acceleration is

a = d²x / dt²

If x = A cos wt

v = dx / dt = -A w sin (wt +Ф)

a = d²x / dt² = - A w² cos (wt+Ф)

d) we substitute in Newton's second law

d²x / dt² = -k / m x

We call

w² = k / m

e) substitute to find w

-A w² cos (wt+Ф) = -k / m A cos (wt+Ф)

w² = k / m

Angular velocity and frequency are related

w = 2π f

f = 1 / T

We substitute

T = 2π / w

T = 2π √m / k

g) v= - A w sin (wt+Ф)

h) acceleration is

a = - A w² cos (wt+Ф)

An airplane is flying at a speed of 45 m/s when it drops a 40 kg food package to the Polar exploration team. If the plane drops

Alina [70]

To solve this problem we will apply the concepts related to energy conservation, so the potential energy in the package must be equivalent to its kinetic energy. From there we will find the speed of the package in the vertical component. The horizontal component is given, as it is the same as the one the plane is traveling to. Vectorially we will end up finding its magnitude. So,

$PE = KE$

$mgh = \frac{1}{2}mv^2$

Here,

m = Mass

g = Gravity

h = Height

v = Velocity

Rearranging to find the velocity

$v = \sqrt{2gh}$

Replacing,

$v = \sqrt{2(9.8)(120)}$

$v = 48.49m/s$

Using the vector properties the magnitude of the velocity vector would be given by,

$|V| = \sqrt{v_x^2+v_y^2}$

$|V| = \sqrt{45^2+48.42^2}$

$|V| = 66.2m/s$

Therefore the package is moving to 66.2m/s

Levart [38]

Most of the excess energy is released as waste heat into the air surrounding the engine. Small amounts of excess energy are also released as sound energy, and as electrical energy generated by the alternator in a car's engine.
