Answer: Earthquakes and Volcanic eruptions
Explanation:
You did not attach a picture however, this should be the correct answer.
Mid-oceanic ridge plate boundaries such as the Mid-Atlantic Ridge form as a result of plate separating at the boundary. This leads to earthquakes due to the forces of tension acting on the plates.
When this happens, the mantle is exposed and therefore there will be volcanic eruptions as the lava comes to the surface as magma. When this magma cools it creates new seafloors and underwater mountains.

What is needed in order to create a magnetic field
Electric currents, changes in electric fields, or charged particles with inherent angular momentum produce the magnetic field.
How do magnetic fields work?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.

All solid objects will deform when enough force is applied.
O True
False
Answer:
Solid objects will deform when adequate loads are applied to them; if the material is elastic, the object will return to its initial shape and size after removal. This is in contrast to plasticity, in which the object fails to do so and instead remains in its deformed state.
Explanation:
Answer:
It is false
Explanation:
because when it like a rolling ball it can deform no matter what unlesss you throw it at the ground really hard then it breaks but a soft or sometimes metal yeah it can deform but not all things solid deform.

When we sit on a chair and study for 2-3 hours, we are not doing work from a physicists point of view. Why?
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.

A Carnot engine uses a steam boiler at 100°C as the high-temperature reservoir. The low-temperature reservoir is the outside environment at 35.0°C. Energy is exhausted to the low-temperature reservoir at a rate of 150 W. Hint (a) Determine the efficiency of the engine. (Give your answer as a percentage.) eC = % (b) Determine the useful power output of the heat engine (in W). output = W (c) How much steam (in kg) will it cause to condense in the high-temperature reservoir in 2.00 h? condensate = kg
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
If a book has a weight of 23.3 N on earth, what is its mass
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
Un circuito que contiene una batería de 6.0 V se conecta con un resistor de 81.0 Ω. Si después de media hora el voltaje de la batería disminuye a 4.5 V, cómo cambia la corriente en el circuito respecto al principio
Answer:
AI = 0.019 A
Explanation:
The computation of the current change and the same compared to the staring is shown below;
I = v ÷ R
= 5v ÷ 81.0
I = 0.074 A
Now
I = v ÷ r
= 6v ÷ 81.0
I = 0.055A
Now
I = 0.074A - 0.055A
AI = 0.019 A
The same would be considered

Un cuerpo se mueve por una carretera que tiene rozamiento.¿Podríamos aplicar el principio de conservación de la energía mecánica? ¿Qué requisitos se han de cumplir para poder aplicarla?
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.

How does the circuit structure affect the brightness of a bulb? How does the circuit structure affect the energy required to keep bulbs lit? Summarize some of the tradeoffs (pros and cons) of wiring bulbs in series vs. Parallel.
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

O visible light and X-rays
O microwaves and gamma rays
gamma rays and X-rays
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.
What is Electromagnetic Spectrum ?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.
