A child is perched perilously above a 150m ravine. The child has a mass of 45kg. How much

Finger [1]

Answer:

Explanation:

<u>Gravitational Potential Energy</u>

Gravitational potential energy is the energy stored in an object because of its vertical position or height in a gravitational field.

It can be calculated with the equation:

U=m.g.h

Where m is the mass of the object, h is the height with respect to a fixed reference, and g is the acceleration of gravity or $9.8\ m/s^2$ .

The child of mass m=45 Kg is perched above a h=150 m ravine. His gravitational potential energy is:

$U=45~Kg\cdot 9.8\ m/s^2\cdot 150\ m$

U = 66,150 J

A health care provider suspects a client has developed posttraumatic stress disorder (PTSD). Select the necessary criterion to v

julia-pushkina [17]

Answer:

The necessary criterion to validate the PTSD (posttraumatic stress disorder) is criterion A, (one required): the person was exposed to: death, threatened death, actual or threatened serious injury, or actual or threatened sexual violence,one symptom (or more): inability to remember an important aspect of the event, from criterion B, one symptom (or more): wars survivors, persistent and exaggerated negative beliefs about oneself, others, or the world, and persistent negative emotional state.to criterion C: old age abused; persistent distorted cognitions about the cause or consequences of the event.

Explanation:

DSM-5 PTSD diagnosis measures, assesses, or evaluates dissociative subtypes, which causes disconnection from the surrounding world or from oneself.

The DSM-5 manual, for the PTSD diagnosis, includes the DSM-IV/ICD-9 309.81 to the ICD-10 F43.10.

An experienced mental health provider, such as a psychiatrist or psychologist, is generally in charge of the diagnosis.

To be diagnosed with PTSD, an adult must have at least one avoidance symptom re-experiencing symptom for at least 1 month.

Ehy Newton's law of gravitation also called universal law?

pychu [463]

Answer:

Gravity is a natural phenomenon that causes all massive objects to attract each other. The magnitude or force of this interaction depends on the masses and distance of the bodies. This causes objects to fall toward Earth, for example, and keep satellites and celestial bodies in their orbits, such as the Earth's orbit around the Sun. Gravity also causes the tidal phenomenon.

In physics, gravity can be approximated by Isaac Newton's laws of gravity. Although the accuracy of the law is sufficient, for example, when calculating the orbits of spacecraft, gravity is best described by Albert Einstein’s general theory of relativity, in which it is considered the curvature of space-time.

In which of these situations, is mechanical energy being conserved? (Neglect, air resistance, friction, and breaking) Check all

Amiraneli [1.4K]

1) Mechanical energy is conserved in all the situations mentioned

2) True

3) Potential energy

4) The potential energy is 490 J

5) The potential energy is 750,000 J

Explanation:

1)

The mechanical energy of an object is the sum of its potential energy (PE) and its kinetic energy (KE):

$E=PE+KE$

When there are no conservative forces acting on the object (i.e. air resistance of friction), the mechanical energy is always conserved, so it is constant:

$E=const.$

This means that there is a continuous conversion between potential energy and kinetic energy.

In all the examples mentioned here, there are no air resistance or friction acting on the system: therefore, mechanical energy is conserved in all cases.

2)

The potential energy of the object falling to the ground is given by

$PE=mgh$

where

m is the mass

g is the acceleration of gravity

h is the height of the object above the ground

While the kinetic energy is given by

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

where

v is the speed of the object

As the object falls, its height h decreases, while the speed v increases: therefore, the potential energy decreases and it is converted into kinetinc energy, which increases.

3)

The energy possessed by an object due to its position is called potential energy. It can be of two types:

- Gravitational potential energy: it is the energy possessed by an object due to its position in a gravitational field. It is given by

$PE=mgh$

where m is the mass, g the acceleration due to gravity, h the height of the object

- Elastic potential energy: it is the energy stored in an elastic object which is compressed or stretched - it is given by

$PE=\frac{1}{2}kx^2$
