A) The sum of the kinetic energy and the gravitational potential energy changes by an amount equal to the energy dissipated by friction,

Explanation:

The sum of the kinetic energy and the gravitational potential energy changes by an amount equal to the energy dissipated by friction.

The principle of conservation of energy states that, the total mechanical energy of an isolated system is always conserved.

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: [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]

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:

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.

Explanation:

Solar radiation that is not absorbed or reflected by the atmosphere (for example by clouds) reaches the surface of the Earth. The Earth absorbs most of the energy reaching its surface, a small fraction is reflected. In total approximately 70% of incoming radiation is absorbed by the atmosphere and the Earth’s surface while around 30% is reflected back to space and does not heat the surface. The Earth radiates energy at wavelengths much longer than the Sun because it is colder. Part of this longwave radiation is absorbed by greenhouse gases which then radiate energy into all directions, including downwards and thereby trapping heat in the atmosphere.

Explanation:

Lift occurs when a moving flow of gas is turned by a solid object. The flow is turned in one direction, and the lift is generated in the opposite direction, according to Newton's Third Law of action and reaction. Because air is a gas and the molecules are free to move about, any solid surface can deflect a flow.

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].
