Answer:
B. Cinética, debido a que esta energía está asociada con la velocidad que posee el tren.
Explanation:
Un tren de alta velocidad (TAV) o tren bala es aquel que alcanza velocidades iguales o superiores a 200 km/h. La energía que tiene el tren en su recorrido habitual es
A. Cinética, debido a que existen trenes elevados los cuales poseen altura y la altura está asociada con la energía cinética.
B. Cinética, debido a que esta energía está asociada con la velocidad que posee el tren.
C. Rápida, porque la energía cinética es sinónimo de rápido.
D. Potencial, debido a la potencia que tiene el tren para moverse.
Solution:
La energía cinética es la energía contenida en un objeto en movimiento. La energía cinética se puede definir como la cantidad de energía necesaria para que un objeto se acelere desde el reposo hasta su velocidad final.
La energía cinética (KE) viene dada por:
KE = (1/2) * masa * velocidad²
Podemos ver que la energía cinética depende de la masa del objeto y la velocidad del objeto.
El tren de alta velocidad posee energía cinética debido a la velocidad del tren.

What's the Genotype for these? If your answer is something off-topic I ShAlL rEpOrT iT u.U
Pick any free letter for each trait. For example, "A" for the dominant allele and "a" for the recessive allele for the number of arms. Assuming complete dominance, the genotype for the dominant trait will always have at least one "capital" allele, so a creature with 2 arms would have genotype either AA (homzygous dominant) or Aa (heterozygous), while a creature with the recessive trait of having 4 arms will always be homzygous recessive with genotype aa.

If you are sitting 8.20 m from a
70.0 W speaker, what is the
sound level in dB?
(Treat the speaker as a point source.)
(Unit = dB)
The sound level will be 109 decibels. If a person exceed hear a sound more than the certain sound level, the person hearing may damage.
What is sound level?Sound level is the intensity to measure the sound. Decibels are used to quantify sound level.
Sound level or the sound intensity is the ratio of the power to the surface area;
[tex]\rm Intensity = \frac{Pow\pi er }{Surface \ area} \\\\ \rm Intensity = \frac{70}{ 4 \times \pi \times 8 \times 20^{2} } \\\\ I = \ 0.082 \ W/m^2[/tex]
The conversion of the obtained value into the decibel as;
[tex]\rm I = 10 \times log \frac{I}{1 \TIMES 10^{-12}} \\\\\ I = 109 \ decibel[/tex]
Hence, the sound level will be 109 decibels.

Many battery-powered devices come with cords that allow them to be
plugged into electrical outlets. What change has to take place inside
the power cord in order for the device to function properly?
Answer:
The change that has to take place inside the power cord in order for the device to function properly include;
The changing of the alternating current (AC) from the electrical outlet to the direct current having a specific voltage and current value with which the device can be powered
Explanation:
A battery powered device makes use of direct current (DC) electric power from a battery, while the power normally given out at an electrical outlet comes as an alternating current (AC) electric power source.
The power cord for battery-powered device, also known as an AC/DC adapter, that allows them to be plugged into electrical outlets converts the AC electric current it obtains from the electrical outlets to DC electrical current of the appropriate voltage and amperage that the device can make use of for electric power to function and for charging the battery which is the power source for the device
Therefore, the change that has to take place in the power cord is the conversion of the electric outlet alternating current (AC) voltage and amperage values, into direct current (DC) of the required voltage and current for the device

The title is the journey of the ice cube. (change it if you want)
Main character - ice cube
There was an ice cube made by the water from the freezer in an ice shop.
The ice cube, with a bunch of other ice cubes, were taken to be packed and sold to a restaurant. The ice cube was excited to where he was going while the other ice cubes are just meh. Now that the ice cubes arrived, a restaurant worker stores the ice cubes in a cooler and later used to put ice in a lemonade. While the lemonade in a glass cup was carried outside the porch of the restaurant by the waiter, the ice cube was fascinated by the environment of the restaurant. The waiter finally serves the thirsty customer and the customer drank almost half of the lemonade but the ice cube did not get in the man's mouth. Instead the other ice cubes went. The ice cube feared the person. Shortly after checking his phone, the customer was about to reach on to the glass until the hands accidentally pushes the glass over and falls. The ice cube and the remaining ice cubes spread away with the wasted lemonade liquid. No one bothered cleaning up the ice cubes, only the glass shards because the floor is a smooth concrete. Outside was really hot from the sun anyways so it would melt the ice cube and sooner evaporate. As it was in liquid form, the "ice cube" was feeling relaxed because it was just chilling on the floor. And when it evaporates, the ice cubes becomes more fascinated since it goes up to the sky while having a sky-view from above.
That is the end.

Read the excerpt from " Crossing the Brooklyn Ferry." Flood-tide below me! I see you face to face! Clouds of the west – sun there half an hour high – I see you also face to face. Which statement best describes the effect of repeating the phrase "face to face"? It shows that the narrator sees the facial features of others. It demonstrates that the narrator is surrounded by nature. It demonstrates that the narrator is surrounded by people. It shows that the narrator is suspicious of the sea and sky.
Answer:
It demonstrates that the narrator is surrounded by nature.
Explanation:
Walt Whitman's "Crossing the Brooklyn Ferry" is a free verse poem written about the speaker's return trip on a ferry. He talks about his daily commute on the Brooklyn ferry, like the other commuters, and how they all share the same experience.
The given lines are from the very first stanza of the poem. The speaker repeats "face-to-face" when talking about nature. He sees the "flood-tide below" and the "clouds" high in the sky. This repetition demonstrates that he is surrounded by nature, amidst the throng of people around him. This shows the speaker's attitude of seeing the beauty of nature in any way he can, despite the bustle of commuting from Brooklyn to Manhattan.

Stephen Strasburg throws out the opening pitch at Nationals Park. The ball starts at rest, but
accelerates to 42 m/s (approximately 95 mph) in the 0.02 seconds it takes to throw. If the ball
has a mass of 0.145 kg, how much force did Strasburg throw with?
Answer:
Force = 304.5 Newton
Explanation:
Given the following data;
Initial velocity, u = 0m/s (since it started from rest).
Final velocity, v = 42m/s
Time, t = 0.02 secs
Mass = 0.145 kg
To find the force;
First of all, we would have to determine the acceleration of the ball;
Acceleration = (v - u)/t
Acceleration = (42 - 0)/0.02
Acceleration = 42/0.02
Acceleration = 2100 m/s²
Now, we solve for the force;
Force = mass * acceleration
Force = 0.145 * 2100
Force = 304.5 Newton

ay wants to buy a new fireplace insert that will burn gas instead of wood. She normally uses two cords of wood in the winter. Wood costs $250/cord. She is interested in knowing how much she will save if she burns gas in the fireplace insert. Gas costs $0.91 per therm. One therm is 100,000 BTU. The fireplace insert burns 33,000 BTU per hour. Kay figures she will burn the fireplace 5 hours per day for 120 days. How much will she save in one winter if she burns gas instead of wood
Answer:
Saved Money = $ 319.82
Explanation:
First, we will calculate the cost of wood:
[tex]Wood\ Cost = (No.\ of\ Cords)(Unit\ Cost)\\Wood\ Cost = (2 cords)(\$ 250/cord)\\Wood\ Cost = \$ 500\\[/tex]
Now, we calculate the time to burn gas:
[tex]Time\ to\ burn\ gas = (5\ hours/day)(120\ days)\\Time\ to\ burn\ gas = 600\ hr\\[/tex]
Now, we calculate the energy:
[tex]Energy\ Required = (600\ hr)(33000\ BTU/hr)(\frac{1\ therm}{100000\ BTU})\\\\Energy\ Required = 198\ therm\\[/tex]
Now, we will calculate the cost of gas:
[tex]Gas\ Cost = (Energy\ Required)(Unit\ Cost)\\Gas\ Cost = (198\ therm)(\$\ 0.91/therm)\\Gas\ Cost = \$\ 180.18\\[/tex]
Now, we will calculate the amount of money saved:
[tex]Saved\ Money = Wood\ Cost - Gas\ Cost\\Saved\ Money = \$\ 500 - \$\ 180.18\\[/tex]
Saved Money = $ 319.82

5. Relationships in a community can be cooperative or competitive.
True
False
Answer:
True
Explanation:
is the correct answer
Answer:
This is True
Explanation:
Communities cooperate by simply co-existing and working together to benefit the community and offering their goods and services. Some programs in a community offer social work, like volunteering and charities, which help people in need in a community.
They can also be competitive because there are lots of the same goods and services offered throughout the city, so businesses have to compete for sales to attract consumers in the communities.

Explanation:
Jenny and anne wanted to see who could throw the ball the hardest. they decided to each throw a ball against the wall as hard as they could and measured how far the ball rolled away from the wall. what might be the variables in this experiment;
Solution:
There are different type of collisions. In an inelastic collision, momentum is conserved and there is loss in kinetic energy while in an elastic collision, momentum is not conserved and there is no loss in kinetic energy.
During inelastic collision, the objects stick together while during an elastic collision, the objects separate.
When the ball is thrown against the stationary wall, there is momentum due to the force of impact. The distance at which the ball is rolled away from the wall depends on:
a) mass of the ball, b) velocity of the ball, c) mass of the wall d) type of collision (elastic or inelastic)
