Answer:

Sí se puede aplicar el Principio de Conservación de la Energía Mécanica siempre y cuando se considere los efectos de pérdida de energía a causa del rozamiento, de lo contrario, no se cumpliría el requisito de conservación derivado del citado principio de conservación.  

Explanation:

Consideremos que el cuerpo representa nuestro sistema de estudio, el cual se desplaza por una carretera y experimenta rozamiento, significando cambios en la energía cinética y potencial gravitacional. La presencia de rozamiento indica una disipación de la energía del cuerpo, cuya energía mecánica total disminuye, significando un sistema no conservativo.

Explanation:

because the same current flows through the lamps and the total voltage across all the lamps is the sum of all the separate voltages across them.

Answer:

It controls the amount of current.

Explanation:

A resistor helps control and maintain the circuit which is it's main function.

Electric currents, changes in electric fields, or charged particles with inherent angular momentum produce the magnetic field.

A magnetic field, a vector field that describes the magnetic field on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field is subject to a force that is perpendicular to the magnetic field and has its own velocity.

The force that draws objects like iron is known as the magnetic force. The attraction or repellence between two magnetic materials is known as magnetic force. Iron is one of the ferromagnetic materials.

Given the facts, the magnetic field is typically present whenever charged particles with intrinsic angular momentum or spin are in the field or space, as well as whenever there are changes in the electric fields or currents.

Now, two of Maxwell's equations explain the magnetic fields produced by electric currents and shifting electric fields.

Magnetic fields are produced whenever a charge moves. When more charge is transferred about, a magnetic field grows stronger.

Hence, when there is an electric field, there is also a magnetic field.

Answer:

(a) η = 0.1742 = 17.42 %

(b) W = 31.64 W

(c) m = 0.58 kg

Explanation:

(a)

The efficiency of a Carnot's engine is given as follows:

[tex]\eta = 1-\frac{T_2}{T_1}[/tex]

where,

η = efficiency = ?

T₁ = source temperature = 100°C + 273 = 373 K

T₂ = sink temperature = 35°C + 273 = 308 K

Therefore,

[tex]\eta = 1 - \frac{308\ k}{373\ k} \\[/tex]

η = 0.1742 = 17.42 %

(b)

Another formula for the efficiency of Carnot's Engine is:

[tex]\eta = 1 - \frac{Q_2}{Q_1}[/tex]

where,

Q₁ = Input heat rate

Q₂ = Heat rejected = 150 W

Therefore,

[tex]0.1742 = 1 - \frac{150\ W}{Q_1}\\\\ \frac{150\ W}{Q_1} = 1-0.1742\\\\Q_1 = \frac{150\ W}{0.8258}[/tex]

Q₁ = 181.64 W

Now, for the useful power output:

[tex]W = Q_1-Q_2\\W = 181.64\ W - 150\ W\\W = 31.64\ W[/tex]

where,

W = Useful Output

W = 31.64 W

(c)

The heat required to condense steam i given as:

[tex]Q = mH\\Q_1t=mH\\m = \frac{Q_1t}{H}[/tex]

where,

m = mass of steam condensed = ?

t = time = 2 h = 7200 s

H = Latent heat of condensation of steam = 2260 KJ/kg = 2260000 J/kg

Therefore,

[tex]m = \frac{(181.64\ W)(7200\ s)}{(2260000\ J/kg)}[/tex]

m = 0.58 kg

Answer:

2.38 kg

Explanation:

by definition, weight in physics is the force of gravity (Fg)

Fg = mass x gravity or mg

gravity is 9.8 m/s^2

N = kg m/s^2

Fg = mg

23.3 kg m/s^2 = 9.8 m/s^2 x m

23.3 kg m/s^2 / 9.8 m/s^2 = m    >>> m/s^2 cancel out

23.3/9.8 = 2.37755 kg

m = 2.38 kg

In the context of physics, work is defined to be the movement of an object when you apply a (pushing or pulling) force.

If you lifted a box to move it upward, then you are doing work. If you slide that box along the floor, then you are also doing work. However, if you try to lift something very heavy, but cannot move it at all, then 0 work is being applied. This is because the object hasn't moved. You need displacement to have work happen.

So that's why a physicist would not consider studying doing "work" (in the context of physics), though I'm sure they would be able to agree that studying does exercise the mind.

What are the following statements?

Answer:

Part A

The relationship between the circuit structure and the brightness of the bulb are;

The brightness of the bulb depends on the voltage to which the bulb is connected to

Bulbs connected in parallel, are connected directly to the voltage of the power source and are therefore brighter than bulbs arranged in series due to the reduced potential difference between bulbs in series and the voltage source

Part B

Given that bulbs are brighter when arranged in parallel, they require more energy to keep the bulbs lit than when they are arranged in series

Part C

The pros and cons of wiring bulbs in series and parallel are;

Series Circuits Disadvantage

i) A failure of one bulb arranged in series can lead to a failure of the circuit

ii) Bulbs arranged in series are not as bright as bulbs arranged in parallel

iii) When the number of bulbs arranged in a series are increased, the brightness decreases

iv) The bulbs cannot be controlled independently

Advantages of Series Circuits

i) Series circuits consume less energy and the batteries last longer when the attached bulbs are arranged in series

Disadvantage of bulbs arranged in parallel

i) The battery power quickly consumed

The Advantages of Bulbs in Parallel

i) The bulbs light brighter when they are in parallel

ii) The bulbs can be individually controlled

iii) The current can flow through more than one path way

iv) When one bulb fuses, the others in the circuit keep working

Answer:

Gamma rays and x rays

Explanation: just took the test

Gamma rays and X-rays have higher frequencies than the waves that make up ultraviolet light. Hence option D is correct.

Electromagnetic spectrum is nothing but the range of wavelengths or frequencies on which electromagnetic radiation extend. it is whole distribution of electromagnetic waves according to frequency or wavelength. Electromagnetic wave is nothing but a photon which carries energy. Photon wave has frequency, wavelength as well as amplitude.

Electromagnetic spectrum is show in figure.

There is inverse relation between wavelength and frequency as υ = c/λ

where υ is the frequency, λ is the wavelength and c is the speed of light.

as wavelength increases, frequency decreases vice verse.

In this figure we can see that radio waves has highest wavelength hence it has lowest frequency. X ray and gamma rays has lowest wavelength hence it has highest frequency.

Hence option D is correct.
