How does the intensity of light change for a location depending on the season?

Answers

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.

In summer the axis points to the sun, which is why more intensity per unit area arrives. In winter the axis moves away from the sun intensity per unit area is less

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.

4.- Una vagoneta de 1000 kg de peso parte del reposo en el punto 1 y desciende, sin rozamiento, por la vía indicada en la figura. A) Calcular la fuerza que la vía ejerce sobre la vagoneta en el punto 2, donde el radio de curvatura es de 6 m. B) Determinar el mínimo valor del radio de curvatura en el punto 3 para salvar dicho punto

Answers

Answer:

A) 49,050 N

B) 16 m

Explanation:

Question:

El dibujo de la pregunta se obtiene de un documento titulado "TRABAJO DIVERSO Y ENERGÍA" que se encuentra en línea y se presenta aquí.

La masa dada del vagón, m = 1,000 kg

La altura del punto en el que descansa el vagón, punto 1, h₁ = 12 m

A) El radio en el punto 2, el punto más bajo, R = 6 m

La fuerza, 'N', que la vía ejerce sobre el vagón en el punto 1 viene dada por la siguiente relación;

N = El peso del vagón + La fuerza de movimiento del vagón

∴ N = m × g + m × a

Dónde;

g = La aceleración debida a la gravedad ≈ 9,81 m / s²

a = La aceleración del vagón

Observamos que para el movimiento circular, la fuerza de movimiento del vagón, m × a = La fuerza centrípeta que actúa sobre el vagón = m × v² / R

∴ m × a = m × v² / R

Dónde;

v² = La velocidad del vagón en el punto 2 = 2 · g · h₁

Por lo tanto;

N = m × g + m × a = m × g + m × v² / R = m × g + m × 2 · g · h₁ / R

∴ N = 1000 × 9,81 + 1000 × 2 × 9,81 × 12/6 = 49,050

La fuerza que ejerce el vagón en el punto 2, N = 49,050 N

B) En el punto 3, tenemos;

N = m · g - m · a₃

La fuerza centrípeta en el punto 3, m · a₃ = m · v₃² / R₃

∴ La altura en el punto 3, h₃ = 4 m

El cuadrado de la velocidad en el punto 3, v₃² = 2 · g · (h₁ - h₃)

Para que el vagón esté seguro en el punto 3, la fuerza de la vía sobre el vagón, N = 0 para que el vagón permanezca en la vía actuando

Por lo tanto;

N = m · g - m · a₃ = 0

m · g = m · a₃ = m · v₃² / R₃ = m · (2 ​​· g · (h₁ - h₃)) / R₃

∴ R₃ = (2 · g · (h₁ - h₃)) / g = (2 · (h₁ - h₃)) = 2 × (12 - 4) = 16

El radio de curvatura en el punto 3 para que el punto sea seguro es R₃ = 16 m.

A 10kg box accelerates forward at a rate of 12 m/s^2. What is the force acting on the box?
120N
N8'0
ON

Answers

Answer:

120N

Explanation:

Newton's second law formula: F= ma

given that m = 10 kg, a = 12 m/s^2

F = ma = 10 kg * 12 m/s^2 = 120 kgm/s^2 = 120 N

The force acting on the box is equal to 120N. Therefore, option (A) is correct.

What is Newton's second law of motion?

According to Newton's 2nd law of motion, The force acting on an object is equal to mass times the acceleration of that object.

This law tells that the acceleration of a moving body depends upon two variables in which one is the mass of the object which is constant while the other is the force acting on that object. The acceleration of an object increases as the mass of the object is less.

The mathematical equation of the second law of motion can be written as:

F = ma

Given, the mass of the box, m = 10 Kg

The acceleration of the box, a = 12m/s²

We can find the force acting on the box by putting the values a and m:

Force acting on the box, F = 10 ×12 = 120 N

Therefore, the force acting on the box is equal to 120 newtons.

An astronaut weighs 200 N on the Moon where gravity is 1.62 m/s/s. Find his weight on Earth. HELP PLEASE FAST

Answers

Answer:

the weight of the astronaut on Earth is 1209.88 N

Explanation:

Given;

weight of the astronaut, W = 200 N

acceleration due to gravity on moon, g = 1.62 m/s²

Apply Newton's second law of motion to determine the mass of the astronaut;

F = ma = mg

m = F/g

m = 200 / 1.62

m = 123.457 kg

The weight of the astronaut on Earth is calculated as follows;

F = mg

where;

g is acceleration due to gravity on Earth = 9.8 m/s²

F = 123.457 x 9.8

F = 1209.88 N

Therefore, the weight of the astronaut on Earth is 1209.88 N

Explanation:

To get the displacement, we will make use of the expression;

[tex]D = \sqrt{(\sum d_x)^2+(\sum d_y)^2}[/tex]

Taking the sum of the distances along the x;

dx = 1km - 4km

dx = -3km

Taking the sum of the distances along the y axis

dy = 3km - 3km

dy = 0km

Substitute into the formula above;

[tex]R = \sqrt{(-3)^2+(0)^2}\\R = \sqrt{9} \\R = 3km\\[/tex]

Oxygen has 6 valence electrons. how many hydrogen atoms (who have 1 valence electrons) can bond with it? remember the octet rule.

Answers

Answer:

Oxygen starts with six valance electrons and ends with six valance electrons but after bonding has parts of the densities of 8 electrons

Explanation:

Chemical bonding does not increase the valance electrons. Oxygen has 6 valence electrons. Bonding is sharing of valance electrons

The electron density of two of the valance electrons of Oxygen are shared with the Hydrogen atoms. The Hydrogen atoms is turn share part of the electron density of their single electron with Oxygen.

This means that there are parts of 8 electron densities around the Oxygen. This does not increase the number of valance electrons of Oxygen. (Note the sharing is very unfair, Oxygen gets more than its

share of the electron densities of the two electrons used for the chemical bond.

An observer notices that 12 waves pass by in 4 seconds. What is the frequency of these waves? 0.33 Hz 16 Hz 48 Hz 3 Hz

Answers

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.

What is a frequency?

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.
