Answer:

The ratio of forces is 22 : 3.

Explanation:

Case I:

initial velocity, u = 35 mph

final velocity, v = 0

time, t = 15 ms

Case II:

initial velocity, u = 35 mph

final velocity, v = 0

time, t' = 110 ms

let the mass is m.

According to the Newton's second law, the force is given by the rate of change of momentum.

So

[tex]F =\frac{m(v-u)}{t}\\\\F'= \frac{m(v-u)}{t'}\\\\So, \frac{F}{F'} =\frac{t'}{t}\\\\\frac{F}{F'}=\frac{110}{15}=22:3[/tex]

Answer:

1084860 N

Explanation:

Applying,

P = ρgh................ Equation 1

Where P = pressure, ρ = density, h = height, g = acceleration due to gravity.

From the question,

Given:  ρ = 1025 kg/m³, h = 9 m

Constant: g = 9.8 m/s²

Substitute these values into equation 1

P = (1025)(9)(9.8)

P = 90405 N/m²

Also,

P = F/A.............. Equation 2

Where, F = Force, A = Area.

Make F the subject of the equation

F = PA............... Equation 2

Given: A = 12m²

F = 12(90405)

F = 1084860 N

Explanation:

From the question given above, the following data were obtained:

Mass (m) = 5 Kg

Coefficient of friction (μ) = 0.36

Normal reaction (N) =?

Next, we shall determine the weight of the body. This can be obtained as follow:

Mass (m) = 5 Kg

Acceleration due to gravity (g) = 10 m/s²

Weight (W) =?

W = mg

W = 5 × 10

W = 50 N

Finally, we shall determine the normal reaction. This can be obtained as follow:

Weight (W) = 50 N

Normal reaction (N) =?

Normal reaction = weight of the body

N = W = 50 N

Thus, the normal reaction acting on the body is 50 N

La respuesta correcta para esta pregunta abierta es la siguiente.

A pesar de que se te olvidó especificar el país al que te refieres y a la fecha específica para saber de qué época estás hablando, te podemos ayudar comentando lo siguiente.

¿Qué juegos se practicaban en esa Época?

Anterior al surgimiento de la era digital y la era de los "gammers," los niños y la juventud en general salían a la calle o al parque a realizar diferentes actividades físicas y recreativas. Había juegos de ronda, juegos deportivos, juegos de destreza, y juegos de mesa.

¿Qué nombre tenían los juegos?

Había juegos que se llamaba "Doña Blanca," "La Roña," "Lobo estás ahí," "Las escondidas," "canicas," el yoyo," "el trompo," "el burro castigado," "las cebollitas," "el látigo," además de las "cascaritas" que eran juegos de soccer o futbol americano en las calles y con equipos formados por tus amigos.

¿En qué consistía cada uno de los juegos?

Si jugabas canicas, tenías que golpear una canica con otra para desplazarla y llevarla a cierto lugar. O tenías que meterla en agujeros.

Si jugabas, "Doña Blanca," formabas un círculo entrelazado de las manos. Mientras cantabas la canción de Doña Blanca, alguien que estaba afuera del círculo trataba de romperlo, tratando de soltar algunas de las manos entrelazadas.

La verdad era sumamente divertido, creativo, te reías, mucho, y lo mejor de todo era que hacías ejercicio y no te quedabas sentado todo el día frente a una pantalla de computadora.

Complete Question:

The Statue of Liberty is made of copper that has turned green because it has undergone a change. What can be said about this change?

Group of answer choices.

A. The change is a physical change because the copper in the statue is still there.

B. The change is a physical change because a new chemical is formed on the outside of the statue.

C. The change is not a physical change because the color of the statue has changed.

D. The change is not a physical change because a new chemical is formed on the outside of the statue.

Answer:

D. The change is not a physical change because a new chemical is formed on the outside of the statue.

Explanation:

A physical change can be defined as a type of change that only affects the physical form of a chemical substance (matter) without having any effect on its chemical properties. Thus, a physical change would only affect the physical appearance and properties of a chemical substance (matter) but not its chemical properties.

This ultimately implies that, a physical change result in a change of matter from one form or phase (liquid, solid or gas) to another without a corresponding change in chemical composition.

Additionally, a physical change is a type of change that involves an increase or decrease in the volume of a physical object (object). Also, this change can be reversed to the original state under certain conditions.

Since the Statue of Liberty which is made of copper turned green, the change is not a physical change because a new chemical is formed on the outside of the statue.

Answer:

a. Energy = 28800000 Joules

b. Energy = 8 Kwh

c. Cost = $4

Explanation:

Given the following data;

Power = 1000 Watts

Time = 8 hours

Cost = $0.5 per KWh

Conversion:

1 hour = 60 * 60 = 3600 seconds

8 hour = 8 * 3600 = 28800 seconds

a. To find much electrical energy, in joules;

Energy = power * time

Energy = 1000 * 28800

Energy = 28800000 Joules

b. To find how much energy is that in kilowatt hours;

Energy = power * time

Energy = 1000 * 8

Energy = 8000 Watt-hour = 8000/1000 = 8 Kwh (1 Kilowatts is equal to 1000 watts).

c. To calculate the cost of using this heater;

Cost = 8 * 0.5

Cost = $4

Answer:

The statements that best compares radiation and conduction are the following: both transfer thermal energy from warm objects to cooler objects and both can transfer energy through matter. The difference is that conduction is through direct heat transfer; whereas, radiation transfers heat through waves.

Answer:

t_total = 6.99 s

Explanation:

It asks us how long it takes to hear the sound, for this we must look for the time (t₁) it takes for the sound to reach the microphone, the time it takes for the video signal (t₂) to reach the television and the time (₃) it takes for the TV sound to reach us, so the total delay time is

         t_total = t₁ + t₂ + t₂

we look for t1, it indicates that the distance x = 22m

          v = x / t

           t = x / v

           t₁ = 22/343

           t₁ = 6.41 10-2 s

time t₂

          t₂ = 4500 103/3 108

          t₂ = 1.5 10-5 s

time t₃

          t₃ = 2/343

          t₃ = 5.83 10⁻³

Total time is

         t_total = t₁ + t₂ + t₃

         t_total = 6.41 10⁻² + ​​1.5 10⁻⁵ + 0.583 10⁻²

         t_total = 6.99 s

Answer:

d- Earth revolves around the sun.

Explanation:

Earth rotation can be defined as the amount of time taken by planet earth to complete its spinning movement on its axis.

This ultimately implies that, the rotation of earth refers to the time taken by earth to rotate once on its axis. One spinning movement of the earth on its axis takes approximately 24 hours to complete with respect to the sun.

On the other hand, earth revolution can be defined as a complete trip along a path around the sun. This path is known as an orbit and it typically takes the Earth 365¼ days to complete it's journey around the Sun.

When a constellation (stars) changes its position in the sky, at the same time of the evening and over a period of several weeks; it ultimately implies or is an evidence that Earth revolves around the sun.
