Answer:

the energy usage of the clock per year is 17.2 kWh

Explanation:

Given;

power drawn by the clock, P = 2 W

duration of the clock's operation, t = 8,600 hours per year

The energy usage of the clock per year is calculated as;

E = Pt

[tex]E = (\frac{2}{1000} )kW \ \times \ 8,600 \ hr\\\\E = 17.2 \ kWh[/tex]

Therefore, the energy usage of the clock per year is 17.2 kWh

Flooding in the southern United States due to El Nino

Explanation:

An El Nino is said to be taking place during the period of a rise in the temperature of the water at the equatorial Pacific above average combined with a weaker than normal east winds.

The opposite condition is La Nina

The effects of an El Nino includes an higher amount of rainfall and can sometimes cause destructive flooding which is observed in the Southern United States from during the fall through spring

The weather that is most likely to occur if there are warmer than average ocean waters in the pacific is flooding due to El Nino in the southern United States.

Explanation:

Answer:

First answer.

Explanation:

There may be a 5N force, but if the frictional force also equals 5N, than they cancel eachother out, resulting in the brick still staying still, as it is resting on a (perfectly) level surface, but any amount of force would make the brick move.

Answer:

I. Potencia mecánica = 20000 Watts.

II. Potencia mecánica = 26 caballos de fuerza.

Explanation:

Dados los siguientes datos;

Trabajo realizado = 60000 julios

Tiempo = 3 segundos

Para encontrar el poder;

I. En vatios:

Potencia mecánica = trabajo realizado / tiempo

Potencia mecánica = 60000/3

Potencia mecánica = 20000 Watts

II. En caballos de fuerza;

1 vatio = 0.0013 caballos de fuerza

20000 Watts = 20000 * 0.0013 = 26 caballos de fuerza.

Potencia mecánica = 26 caballos de fuerza.

Una grua que efectua un trabajo de 60000 J en 3 s, tiene una potencia mecánica de 20000 W o 27 HP.

Una grua efectua un trabajo (W) de 60000 Joule en 3 segundos (t).

La Potencia mecánica (P) se define como la cantidad de trabajo realizado por unidad de tiempo.

[tex]P = \frac{W}{t} = \frac{60000J}{3s} = 20000W[/tex]

Podemos convertir 20000 W a caballos de fuerza usando el factor de conversión 1 HP = 735.5 W.

[tex]20000W \times \frac{1HP}{735.5W} = 27 HP[/tex]

Una grua que efectua un trabajo de 60000 J en 3 s, tiene una potencia mecánica de 20000 W o 27 HP.

RT=R1+R2+R3

Explanation:

Answer: People can introduce their own biases into an experiment.

Explanation:

The scientist had not actually sorted the mice in terms of intelligence which means that the rats in all the groups possessed the same intelligence on average yet the students after assessment, still corroborated his false narrative by stating that the more intelligent mice were better at solving mazes.

This means that somehow, they must have altered the assessment to fit the narrative of the scientist and they might have done this either consciously or unconsciously. This therefore shows that people will usually introduce their own biases into an experiment in order for it to turn out a certain way.

Answer:

The intensity of light can change with the time of the day, season, geographic location, distance from the equator, and weather. It gradually increases from sunrise to the middle of the day and then gradually decreases toward sunset; it is high during summer, moderate in spring and fall, and low during winter time.

Explanation:

translational movement with the tilt of the earth's axis we can explain the change in intensity that an area receives determined with the weather station.

The intensity of the radiation is defined by the relationship between the power on the irradiated surface

        I = P / A

where I is the intensity, P is the power emitted by the sun and A is the area.

The intensity of the radiation that reaches it is around 1400 W / m² in the upper part of the Earth's atmosphere, this amount varies slightly when the planet passes from its furthest point from the sun to its closest point, that is, perihelion to aphelion.

The most important variation of this intensity is due to the fact that it has its axis inclined and the normal to the area changes in relation to the incident radiation during the translational movement around the sun.

In the summer the axis of the earth is inclined towards the sun, so the rays fall more perpendicularly, therefore their absorption over the area is maximum and the temperature rises.

In winter, the earth's axis is tilted away from the sun, so the rays they carry are distributed over a larger surface area and therefore less energy is absorbed per unit area and the temperature decreases.

In the spring and autumn seasons, the Earth's axis is almost vertical, so the absorption is intermediate and the temperature of the Earth is between the two maximums.

Using an analysis of the translational movement with the inclination of the earth's axis, we can explain the change in intensity received by an area determined with the weather station.

Answer:

W = 210 N

Explanation:

For an ideal machine:

[tex]Work\ In = Work\ Out\\(P)(L)=(W)(H)[/tex]

where,

P = Effort = Spring Scale Reading = 70 N

L = Effort Arm = Length of inclined plane = 12 m

W = Actual Load (Weight) to be lifted = ?

H = Load Arm = Height = 4 m

Therefore,

[tex](70\ N)(12\ m) = (W)(4\ m)\\\\W = \frac{(70\ N)(12\ m)}{4\ m}[/tex]

W = 210 N

Answer:

Superconductivity is a phenomenon whereby a charge moves through a material without resistance. In theory this allows electrical energy to be transferred between two points with perfect efficiency, losing nothing to heat it was discovered on April 8, 1911 by Heike Kamerlingh Onnes, who was studying the resistance of solid mercury at cryogenic temperatures using the recently produced liquid helium as a refrigerant. At the temperature of 4.2 K, he observed that the resistance abruptly disappeared.

Answer:

177.87

Explanation:

acellus

The potential difference between the points A and B is 177.9 V.

Potential difference between any two points is the amount of work required to move a unit positive charge along any path from point A to point B without accelerating is referred to as the electric field.

Here,

The charge on the particle, q = +0.00235 C

The change in electric potential energy, ΔU = 0.418 J

The potential difference can be defined as the electric potential energy per unit charge.

Therefore, the potential difference between A and B,

V = ΔU/q

V = 0.418/0.00235

V = 177.9 Volt

Hence,

The potential difference between the points A and B is 177.9 V.
