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]

Answer:

Frequency = 3 Hz

Explanation:

Frequency is a measure of Hertz. Recall that Hertz is the unit expressing cycles/second, where one second is the denominator of the fraction for simplicity. If there are 12 waves every four seconds, and one wave represents one cycle, dividing 12 waves by 4 seconds will give the answer of 3 waves (or cycles) per one second.

The frequency of these waves is 3 Hz. The correct option is D.

Frequency is the number of cycles or oscillations of a wave that occur in one second, measured in Hertz (Hz). It is a fundamental property of waves and is directly related to the energy and wavelength of the wave. The higher the frequency of a wave, the more energy it carries and the shorter its wavelength.

The formula for frequency (f) is:

f = 1 / T

where f is the frequency in Hertz (Hz) and T is the period of the wave in seconds (s). The period is the time it takes for one complete cycle or oscillation of the wave to occur.

Here in the Question,

The frequency of the waves can be calculated using the formula:

frequency = number of waves/time

In this case, the number of waves is 12 and the time is 4 seconds. Substituting these values into the formula, we get:

frequency = 12 waves / 4 seconds = 3 Hz

Therefore, the frequency of these waves is 3 Hz.

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.

Answer:

the maximum height reached by the marble is 11.84 m.

Explanation:

Given;

mass of the marble, m = 0.02 kg

extension of the string, x = 0.08 m

force applied to the string, F = 58 N

Apply the principle of conservation of energy;

elastic potential energy = gravitational potential energy

¹/₂fx = mgh

[tex]h = \frac{Fx}{2mg} \\\\h = \frac{58 \ \times \ 0.08}{2 \ \times \ 0.02 \ \times \ 9.8} \\\\h = 11.84 \ m[/tex]

Therefore, the maximum height reached by the marble is 11.84 m.

Answer:

D. The bowling ball has greater momentum because its mass is

greater than the mass of the tennis ball.

Explanation:

The momentum of a body is defined as the product of mass and velocity. That is;

p = mv

This implies that the momentum of a body depends both on its mass and velocity respectively.

The question clearly states that the tennis ball and the bowling ball have the same speed and are rolling in the same direction. However, the bowling ball has a larger mass compared to the tennis ball hence it possesses a greater momentum than the tennis ball.

Explanation:

the second diagram depicts the phenomenon which is refraction and this stems from light moving from a medium to another......and in this case light moves from a less dense medium to a denser medium hence is refracted away from the normal(the straight line between the medium of air and glass)

PLS GIVE BRAINLY

Diagram B shows the refraction event and this is from light to medium, in this case, the light travels from a slightly narrower area to a compact area and is, therefore, further away from the normal (vertical line between the air and glass).

When a ray of light travels from a dense area to a rare place, it bends away from normal.

Refractive index is also equal to the velocity of light c of a given wavelength in empty space divided by its velocity v in a substance, or n = c/v.

Explanation:

No, the atom will get a positive charge.

Answer:

F = 7.8  10³ N

Explanation:

For this exercise we will use the law of universal Gravitational

         F = G M m / r²

for initial conditions

        F₀ = G M m₀ / r₀²

      They tell us that the mass changed at m = 2m  distance at r = 0.8r₀

we substitute

      F = G M 2m₀ / (0.8 r₀) ²

      F = (GM m₀/ r₀²)   [tex]\frac{2}{0.64}[/tex]

      F = 3.125 F₀

let's calculate

      F = 3.125 2.5 10³

      F = 7.8125 10³ N

Answer:

5 Hz

Explanation:

Given:

Wave velocity ( v ) = 10 m / sec

wavelength ( λ ) = 2 m

We have to calculate Frequency ( f ) :

We know:

v = λ / t [ f = 1 / t ]

v = λ f

= > f = v / λ

Putting values here we get:

= > f = 10 / 2 Hz

= > f = 5 Hz

Hence, frequency of sound is 5 Hz.

Answer:

Avion A (10000 meters).

Explanation:

Deje que la altura de los aviones sea A y B respectivamente.

Dados los siguientes datos;

Altura A = 10000 metros

Altura B = 33300 pies

Para encontrar el avión que voló más alto, tendríamos que hacer alguna conversión de unidades.

Conversión:

Metros a centímetros;

1 metro = 100 cm

10000 metros = 100 * 10000 = 1.000.000 centímetros.

Por lo tanto, la altura A en cm = 1,000,000 centímetros

Pies a centímetros;

1 pie = 30,48 centímetros

33300 pies = 33300 * 30,48 = 1014984 centímetros.

Por lo tanto, la altura B en cm = 1014984 centímetros.

De los cálculos anteriores, podemos deducir que el avión A voló más alto.
