Si pienso en el día de mañana y cuando despierto pienso en el día que tengo por delante y preparo en mi mejor versión trataría de hacer las cosas que me gustan y dejar de lado las que me hacen mal y me estresan para poder disfrutar con total libertad.

Explanation:

Para poder ser la mejor versión de uno mismo una persona tiene que poder expresarse libremente, estar cómoda en el lugar que está para poder sentir y hacer lo que tiene ganas y lo que realmente le hace feliz.

Para algunos esa "mejor versión" puede tener que ver con exigencias físicas, como por ejemplo, entrenar para una carrera o prepararse para un evento deportivo. Para otras personas puede tener que ver con su potencial de estudio o académico por si tiene que rendir un examen, dar una exposición oral, una charla o una prueba laboral. Para otros puede tener que ver con perder miedos y soltar exigencias para poder ser libre de imposiciones externas.

Para que estas situaciones suceda la persona tiene que estar relajada, tranquila, en paz y pudiendo disfrutar en la mayor medida posible de todas sus cualidades y potencias.

Elastic potential energy changes to gravitational potential energy

Explanation:

Step 4 can be described as "elastic potential energy changes to gravitational potential energy." The correct option is A.

Potential energy is the energy stored in an object due to its position, configuration, or state. It is a scalar quantity that describes the amount of energy that an object possesses by virtue of its position or configuration.

Gravitational potential energy, on the other hand, is a specific type of potential energy that is associated with an object's position in a gravitational field. It is defined as the amount of work that must be done to move an object from its current position to a reference position where its gravitational potential energy is zero, typically at an infinite distance away from the gravitational source.

The gravitational potential energy of an object depends on its mass, its height above a reference level, and the strength of the gravitational field in which it is located. The formula for gravitational potential energy is:

PE_grav = mgh

Where PE_grav is the gravitational potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object above the reference level.

So, potential energy is a general term for any type of energy stored in an object, while gravitational potential energy is a specific type of potential energy that is associated with an object's position in a gravitational field.

Here in the Question,

When the toy is pushed down in Step 1, energy is stored in the spring as elastic potential energy. As the spring compresses in Step 2, this potential energy is increased.

When the toy is released in Step 3, the compressed spring rapidly expands and releases the stored elastic potential energy. This energy is then converted into kinetic energy as the toy jumps into the air.

As the toy jumps into the air, its height increases and it gains gravitational potential energy. This energy is due to the toy's position in a gravitational field, and it is stored in the toy's interaction with Earth's gravitational pull.

Therefore, the energy transformation that occurs in Step 4 is from elastic potential energy to gravitational potential energy.

Answer:

The answer is high

Explanation:

I just took the test :))

Higher frequency and higher pitch are produced by sounds with shorter wavelengths. So, long waves sound low and short waves sound high.

Physical characteristics of waves, such as transmission, reflection, polarization, diffraction, and refraction, are examples of wave attributes.

Waves are described mathematically using terms like wavelength, frequency, and amplitude.

Sound and light are two examples of common waves we encounter. Whether you're discussing waves or vibrations.

All of them may be classified according to the following four factors: amplitude, wavelength, frequency, and speed.

According to the graph, pitch perception is influenced by tone strength; below 1000 Hz, pitch tends to decrease with increasing loudness, and beyond 1000 Hz, pitch tends to increase.

Therefore, high pitch that is heard when waves are closely spaced together.

Answer: Rolling Friction

Explanation:A rolling ball stops because the surface on which it rolls resists its motion. A rolling ball stops because of friction.

Explanation:

The formula for finding distance is: speed × time

We must multiply:

200Km/h × 2.5 hours

This gives you 500 Km.

Remember: the formula to work out the distance -  speed x time.

If the train speed is 200 km/h, it travels 200 km/h.

Now, we must multiply 200 by 2.5:

200 x 2.5 = 500

Our answer is 500 Kilometers.

Answer:

Selenium dichloride

Explanation:

Selenium (Se) and Chlorine (Cl) are both elements capable of combining together to form a compound with the chemical formula; SeCl2. Since the chlorine atom is more electronegative than selenium atom, the chlorine pulls more electrons towards itself to form an IONIC bond.

The SeCl2 compound formed is called Selenium dichloride as two atoms of Chlorine are needed to combine with one atom of Selenium to form the compound.

The name of the molecular compound is selenium dichloride (SeCl2).  

• Due to sharing of electrons between selenium and chlorine, Selenium dichloride is considered as covalent compound.  

• Both the elements are non-metals, and thus, would give rise to covalent bond.  

• Selenium is the least electronegative element of the two, so it is written first.  

• After that the more electronegative element is written, and then addition of suffix is done, that is, -ide.  

• If atoms of an element is more than one, then prefixes are supplemented that is mono for 1 atom, di for two atoms, and tri for three atoms.  

Thus, the name of the molecular compound is selenium dichloride.

1. What is the maximum speed when the conditions are mass = 450 kg, initial height = 30 m, and the roller coaster car is initially at rest?

24.2 m/s

2. A computational model predicts the maximum height that a roller coaster car can reach when the lowest height of its journey is at ground level, where it has a speed of 20 m/s. Given these conditions, what is the maximum height?

20.4 m

3. A computational model predicts the speed of a roller coaster car at different heights given its speed at the lowest height of its journey, which is at ground level. The speed at the lowest point is 30 m/s. What is the prediction for its speed when it is at a height of 20 m?

22.5 m/s

4. A computational model predicts the maximum potential energy a roller coaster car can have given its mass and its speed at the lowest point of its journey. Its mass is 350 kg, and it speed at a height of 0 m is 25 m/s. What is the prediction for its maximum potential energy?

109,375 J

5. What is the benefit of using simple computational models in a spreadsheet application, like the one used in this course, to predict mechanical energy and related values?

It is easy to calculate new scenarios.

The predicted speed of roller coaster at the given height is 22.5 m/s. Hence, option (d) is correct.

Given data:

The speed of roller coaster at the lowest point is, v = 30 m/s.

The height of coaster is, h = 20 m.

We need to predict the speed at the given height. So for that purpose, we can use the law of conservation of energy. As per the conservation of energy :

Total energy at height of 20 m = Total energy at bottom

PE + KE = PE' + KE'

Here,

PE and KE are the potential and kinetic energies at respective points.

So,

[tex]mgh + \dfrac{1}{2}mv'^{2}=0 + \dfrac{1}{2}mv'^{2}[/tex]

At bottom, the potential energy is zero.

Solving as,

[tex]gh + \dfrac{1}{2}v'^{2}=\dfrac{1}{2}v^{2}\\\\(9.8 \times 20) + \dfrac{1}{2} \times v'^{2}=\dfrac{1}{2} \times 30^{2}\\\\v' = 22.5 \;\rm m/s[/tex]

Thus, we can conclude that the predicted speed of roller coaster at the given height is 22.5 m/s. Hence, option (d) is correct.
