What is a tsunami? How is it formed?

2 answers:

A tsunami is a series of waves generated in an ocean or other body of water by a disturbance such as an earthquake, landslide, volcanic eruption, or meteorite impact. ... Undersea earthquakes, which typically occur at boundaries between Earth's tectonic plates, cause the water above to be moved up or down

Answers:

1. A tsunami, also known as a seaquake is a seism whose epicenter is located at the depths of the sea or ocean (or any a mass of water) producing the agitation of the waters and forming large waves.

2. How is it formed?

After the seism at the depth of the mass of water begins, and if the seism has a vertical component, the movement causes a displacement of the sea bottom and, consequently, it causes the formation giant waves as the water is displaced because of gravity, trying to return to a stable position.

Now, when the tsunami approaches the coast its speed decreases, because the depth decreases, in other words, the water accumulates when braking, increasing the height of the wave.

And, according to the conservation of energy principle, if the speed of the wave decreases, its height increases.

The kinetic energy of a rotating body is generally written as K=12Iω2, where I is the moment of inertia (also known as rotationa

agasfer [191]

Answer

given,

expression of Kinetic energy of rotating body

$K = \dfrac{1}{2}I\omega^2$

ω = 34.0 rad/s

Assuming mass of the particle equal to 13 Kg

and perpendicular distance from the particle to the axis is r = 1.25 m

now,

moment of inertia of particle = ?

from the given expression

$I= \dfrac{2K}{\omega^2}$ ..............(1)

we know

$K = \dfrac{1}{2}mv^2$

v = r ω

$K = \dfrac{1}{2}mr^2\omega^2$

putting value in equation (1)

$I= \dfrac{2\dfrac{1}{2}mr^2\omega^2}{\omega^2}$

$I =mr^2$

$I =13 \times 1.25^2$

I = 20.3125 kg.m²

Which process is represented by the PV diagram?

Reika [66]

Hi!

The answer would be A. Isobaric Process

<h3>Explanation:</h3>

Isobaric process is a process where the pressure inside a system remains unchanged. In the Pressure Volume graph given, you can see that the pressure (y axis) remains constant with an increasing volume ( x axis). An example of this would be heating a container with a movable piston. Now, the degree of pressure is dependent on the frequency of collisions of particles inside a system on the walls. If this frequency changes, the pressure changes (proportionally). In our example, heating a container with a movable piston results in the particles inside the container to gain kinetic energy and move faster, meaning an increased frequency of collisions (higher pressure), but at the system time the increase in pressure results in the piston being pushed outwards, causing the volume of the container to increase. This results in decreased frequency of collision of the particles with the walls of the container (lesser pressure). This results in the a zero net effect on the pressure.

Hope this helps!
