Answer:
The ocean becomes cooler
Explanation:
La Niña is a phase of a natural climate pattern which occurs across the tropical Pacific Ocean and swings back and forth every 3 - 7 years on the average.
Now, during La Niña, the surface winds across the entire tropical Pacific Ocean are usually stronger than they are on the average, and in return most of the tropical Pacific Ocean will become cooler than they are on average.
Thus, looking at the given options, the correct one is;
The ocean becomes cooler
The way in which La Niña affects the climate of the Pacific Ocean is that: A. The ocean becomes cooler.
La Niña is a complex oceanic and atmospheric phenomenon that occur due to variations in ocean temperatures across the equatorial band of the Pacific Ocean, at a specific period of time in years. Also, it is a colder part of the El Niño-Southern oscillation climate pattern.
Basically, La Niña causes the surface winds blowing across the equatorial band of the Pacific Ocean to be stronger while reducing tropical cyclogenesis. Consequently, this causes the climate of the Pacific Ocean to become cooler.

How is a pitch that is heard when waves are closely spaced together described?
A.the same as when waves are spaced far apart
B.high
C.low
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.
What are wave properties?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.

Its kinetic energy is released into the air at the top of the hill.
B.
Its kinetic energy is added to the potential energy to give it twice as much speed.
C.
Its kinetic energy is converted to potential energy at the very top of the hill.

Una mujer sale de su casa, camina 650 m al Oeste y luego 500 m al Norte hasta llegar al centro comercial donde va a realizar sus compras. Calcular: a) distancia total recorrida y b) magnitud y dirección de su desplazamiento resultante.
Answer:
Explanation:
De la información dada:
La distancia total recorrida= 650 m + 500 m
La distancia total recorrida= 1150 m
La magnitud se puede calcular utilizando el teorema de Pitágoras.
a² = b² + c²
a² = 500² + 650²
a² = 250000 + 422500
a² = 672500
a = [tex]\sqrt{672500}[/tex]
a = 820 m
La dirección del desplazamiento resultante es la dirección noreste desde el punto de partida.
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?(1 point)
18.8 m/s
15.9 m/s
37.5 m/s
22.5 m/
The answers to this test are:
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.
