Answer: In a divergent plate boundary, seafloor spreading taking place. It leads to the formation of oceans as new materials are added here along the mid-oceanic ridge. There occur volcanism and shallow-focus earthquakes.

In a convergent plate boundary, two plates collide to form high mountain belts and also volcanic eruptions take place. There occur long chains of volcanic as well as island arcs, in association with deep-focus earthquakes.

In a transform plate boundary, two plates slide past each other, conserving the plates. Shallow-focus earthquakes are generated here.

The earth has experienced various geological processes, such as weathering and erosion of rocks, earthquakes, volcanic eruptions, mass extinction events, plate tectonic movements and many more. These continuous processes have configured the present shape of the earth's surface.

For example, the breaking up of the supercontinent Pangea divided into Laurasia and Gondwanaland and subsequently formed the present scenario. This separation of continents has taken place due to the convection current that generates in the mantle.

A rock is thrown from a height of 2.0 m at a window that is located 9.0 m above the ground. The initial velocity of the rock is

ELEN [110]

Answer:

The value is $x = 11.81 \ m$

Explanation:

From the question we are told that

The height is h = 2.0 m

The height of the window is $d = 9.0 \ m$

The initial velocity of the rock is $u = 20 \ m/s$

The angle at which it is thrown is $\theta = 40$

Generally the vertical component of the velocity of the stone is mathematically represented as

$v_y = 20 sin (40)$

=> $v_y = 12.86 \ m/s$

Generally the height of the window from the ground is mathematically represented as using kinematic equation as

$d = h + v_yt + \frac{1}{2} gt^2$

=> $9 = 2 +12.86 t + \frac{1}{2} * - 9.8 t^2$

Here g is negative -9.8 m/s^2 because the direction of the stone is against gravity

$4.9 t^2 -12.86 t + 7 =0$

Solving this quadratic equation using quadratic formula we obtain

t = 0.770 s

Generally the velocity of the stone on the x axis is mathematically represented as

$v_x = 20 * cos(40 )$

=> $v_x = 15.32 \ m/s$

Generally the distance between the person throwing the rock and the window is mathematically represented as

$x = v_x * t$

=> $x = 15.32 * 0.771$

=> $x = 11.81 \ m$

The speed of sound in air at room temperature is about s=343 m/s. calculate this speed in miles per hour (mph). (1 mi = 1609 m.)

igor_vitrenko [27]

Given:
1 mi = 1609 m.

Also,
1 hour = 3600 s

Therefore
$343 \, \frac{m}{s} =(343 \, \frac{m}{s} )*(3600 \, \frac{s}{h}) *( \frac{1}{1609}\, \frac{mi}{m})= 767.433 \, \frac{mi}{h}$

Answer: 767.4 mph (nearest tenth)

What happens to atomic numbers as you follow a period across the periodic table

geniusboy [140]

Answer:

As you move across a period, the atomic mass increases because the atomic number also increases

Explanation:

When the atomic number increases, this means that there are more protons and neutrons that add to the atomic mass of an atom.
