Ordovician

Explanation:

Answer:

Ordovician: 470 million years ago

The maximum energy is found in visible light from the following areas of the electromagnetic spectrum. Option A is correct.

The electromagnetic spectrum is seen as colors violet, indigo, blue, green, yellow, orange, and red.  Blue light has a very short wavelength, and so produces a higher amount of energy.

Blue light in the visible zone has a very short wavelength. So that it produces a higher amount of energy that's why the blue part of visible light transfers the most energy.

Visible light from the following regions of the electromagnetic spectrum has the highest energy.

Hence, option A is correct.

Answer:

9.0 m

Explanation:

Applying

V = kq/r......................... Equation 1

Where V = Electric potential, q = charge, r = distance, k = Coulomb's constant.

make r the subject of the equation

r = kq/V................... Equation 2

From the question,

Given: q = 1.00×10⁻⁵ C, V = 10000 V

Constant: k = 9.0×10⁹ N⋅m²/C²

Substitute these values into equation 2

r = (9.0×10⁹×1.00×10⁻⁵)/10000

r = 9.0 m

Answer: C.) Alpha Particles

Explanation: Just took it <3

Answer:

1. Solar wind: a stream of plasma.

2. Coronal mass ejection: includes prominences and solar flares.

3. Gamma ray photon: energy released during nuclear fusion.

Explanation:

1. Solar wind: a stream of plasma i.e charged particles such as ions, protons, alpha, and electrons that continuously escape at high speed from the Sun because of the very hot plasma contained in the solar corona.

2. Coronal mass ejection: includes prominences and solar flares that flow outward into interplanetary space. Thus, it's a release of solar wind plasma and magnetic field from the outer atmosphere or corona of the sun.

Additionally, a solar prominence is also known as filament and it can be defined as a large, bright, dense cloud of luminous ionized gas such as hydrogen, sodium calcium, etc., that erupts (extends) from the surface of the sun. It can linger in the corona for a very long time, reaching hundreds of thousands of kilometers into the sun's atmosphere (space).

3. Gamma ray photon: energy released during nuclear fusion of radioactive isotopes such as cobalt-60 or cesium-137. It has the shortest wavelength and highest energy in the electromagnetic radiation spectrum.

An electromagnetic spectrum refers to a range of frequency and wavelength that an electromagnetic wave is distributed or extends. The electromagnetic spectrum comprises of gamma rays, visible light, ultraviolet radiation, x-rays, radio waves, and infrared radiation.

The mass of the copper coin placed in 101g of water is 135.3g.

The mass of the copper coin can be calculated using the following expression:

Since; Q = mc∆T

Where;

mc∆T (water) = mc∆T (copper)

According to this question;

COPPER METAL:

WATER:

101 × 4.18 × 8.39 = (0.385 × m × 68)

3542.09 = 26.18m

Distancia = 50.04 metros

Explanation:

Dados los siguientes datos;

Velocidad = 10 km/h

Tiempo = 18 segundos

Para encontrar la distancia;

Conversión:

10 km/h = 10 * 1000/3600 = 2.78 m/s

Distancia = velocidad * tiempo

Distancia = 2.78 * 18

Distancia = 50.04 metros

Por lo tanto, el tren viajaría 50.04 metros antes de detenerse por completo.

Explanation:

The question is: You have 500g of ethyl alcohol at a temperature of -40 ° C. How much heat is needed to transform it into steam at a temperature of 150ºC?

Answer: 233700 J heat is needed to transform ethyl alcohol into steam at a temperature of [tex]-40^{o}C[/tex] to [tex]150^{o}C[/tex].

Explanation:

Given: Mass = 500 g

Initial temperature = [tex]-40^{o}C[/tex]

Final temperature = [tex]150^{o}C[/tex]

The standard value of specific heat of ethyl alcohol is [tex]2.46 J/g ^{o}C[/tex].

Formula used to calculate the heat energy is as follows.

[tex]q = m \times C \times (T_{2} - T_{1})[/tex]

where,

q = heat energy

m = mass of substance

C = specific heat

[tex]T_{1}[/tex] = initial temperature

[tex]T_{2}[/tex] = final temperature

Substitute the values into above formula as follows.

[tex]q = m \times C \times (T_{2} - T_{1})\\= 500 g \times 2.46 J/g^{o}C \times [150 - (-40)]^{o}C\\= 233700 J[/tex]

Thus, we can conclude that 233700 J heat is needed to transform ethyl alcohol into steam at a temperature of [tex]-40^{o}C[/tex] to [tex]150^{o}C[/tex].

Answer:

Explanation:

Effort x effort distance = load x resistance  distance

effort distance = 8 m ,

load = 2000N

resistance distance = 1/2 m = 0.5 m

Putting the values in the equation above

effort x 8m = 2000N x .5

effort = 2000 x 0.5 / 8

= 125 N

force required = 125 N .

Answer: [tex]200\Omega[/tex]

Explanation:

Given

The battery used is 6V in magnitude

The current flow is 90 mA

If the resistance of A is [tex]100\Omega[/tex]

Net resistance of the circuit is

[tex]R_{net}=\dfrac{V}{I}\\\\\Rightarrow R_{net}=\dfrac{6}{90\times 10^{-3}}\\\\\Rightarrow R_{net}=\dfrac{200}{3}\Omega[/tex]

If A and B are in parallel then their net resistance must be   [tex]\frac{200}{3}[/tex]

[tex]\dfrac{1}{\frac{200}{3}}=\dfrac{1}{100}+\dfrac{1}{R_b}\\\\\Rightarrow \dfrac{1}{R_b}=\dfrac{3}{200}-\dfrac{1}{100}\\\\\Rightarrow \dfrac{1}{R_b}=\dfrac{3-2}{200}\\\\\Rightarrow R_b=200\Omega[/tex]

The light reflects off a rough surface, what happens to the image is that will occurs No image is formed.

Reflection of light happens when a ray of light strikes a reflective surface and returns to its original medium. This phenomenon allows us to see all bodies that do not produce their own light, called secondary sources of light or simply illuminated bodies.

Diffuse reflection occurs when light reflects off a rough surface and forms a blurry image or no image at all.

Answer:

El magnetismo es el conjunto de fenómenos físicos mediados por campos magnéticos. Estos pueden ser generados por las corrientes eléctricas o por los momentos magnéticos de las partículas constituyentes de los materiales. Es parte de un fenómeno más general: el electromagnetismo. También denomina a la rama de la física que estudia dichos fenómenos.

El níquel, hierro, cobalto y sus aleaciones se encuentran entre algunos de los materiales que presentan propiedades magnéticas que son fácilmente observables, y comúnmente se llaman imanes. Estos materiales son ferromagnéticos e interactúan fuertemente con los campos magnéticos externos a la vez que generan un campo magnético propio. Esto permite la tan conocida repulsión y atracción entre los polos de los imanes. Sin embargo, todos los materiales son influidos, de mayor o menor forma, por la presencia de un campo magnético

Answer:

Inertia.

Explanation:

Inertia can be defined as the tendency of an object or a body to continue in its state of motion or remain at rest unless acted upon by an external force.

In physics, Sir Isaac Newton's first law of motion is known as law of inertia and it states that, an object or a physical body in motion will continue in its state of motion at continuous velocity (the same speed and direction) or, if at rest, will remain at rest unless acted upon by an external force.

For example, the inertia of an object such as a shopping cart is greatly dependent or influenced by its mass; the higher quantity of matter in a shopping cart, the greater will be its tendency to continuously remain at rest.
