He must move the magnet through the inside of the wire coil.
Explanation:
To detect a current Felix must move the magnet around wire coil. This magnetic field around the wire make the electrons mobile and creates an electrical current. Hence. option B is correct.
What is magnetically induced current?Electricity can be created using magnetic' characteristics. Electrons are pushed and pulled by moving magnetic fields. Electrons in metals like are loosely held in their valence shell. Hence they can be transited easily.
The electrons in the wire are pushed when a magnet is moved around it or when a coil of wire is moved around a magnet, producing an electrical current. Kinetic energy, or the energy of motion, is effectively transformed into electrical energy via electricity generators.
The coil of metallic wire can produce a magnetic field in turn also. This is what called the electromagnetic induction. Therefore moving the bar magnet around the coil generates an electric current and results in a deflection in ammeter.

A 920-kg compact car moving at 92 m/s has approximately 3,893,440 Joules of kinetic energy. What is the change in kinetic energy if it is moving at 36 m/s?
Answer:
Change in kinetic energy = 3297280 J
Explanation:
Given that,
Mass, m = 920 kg
Speed of a car, v = 92 m/s
Kinetic energy, K = 3,893,440 J
If the speed of a car, V = 36 m/s
Net kinetic energy is given by :
[tex]K_n=\dfrac{1}{2}mV^2\\\\=\dfrac{1}{2}\times 920\times (36)^2\\\\K_n=596160\ J[/tex]
The change in kinetic energy = 3,893,440 - 596160
= 3297280 J
So, the change in kinetic energy of the car is 3297280 J.

How is a pitch that is heard when waves are closely spaced together described?
A.the same as when waves are spaced far apart
B.high
C.low
Answer:
The answer is high
Explanation:
I just took the test :))
Higher frequency and higher pitch are produced by sounds with shorter wavelengths. So, long waves sound low and short waves sound high.
What are wave properties?Physical characteristics of waves, such as transmission, reflection, polarization, diffraction, and refraction, are examples of wave attributes.
Waves are described mathematically using terms like wavelength, frequency, and amplitude.
Sound and light are two examples of common waves we encounter. Whether you're discussing waves or vibrations.
All of them may be classified according to the following four factors: amplitude, wavelength, frequency, and speed.
According to the graph, pitch perception is influenced by tone strength; below 1000 Hz, pitch tends to decrease with increasing loudness, and beyond 1000 Hz, pitch tends to increase.
Therefore, high pitch that is heard when waves are closely spaced together.

Una mujer sale de su casa, camina 650 m al Oeste y luego 500 m al Norte hasta llegar al centro comercial donde va a realizar sus compras. Calcular: a) distancia total recorrida y b) magnitud y dirección de su desplazamiento resultante.
Answer:
Explanation:
De la información dada:
La distancia total recorrida= 650 m + 500 m
La distancia total recorrida= 1150 m
La magnitud se puede calcular utilizando el teorema de Pitágoras.
a² = b² + c²
a² = 500² + 650²
a² = 250000 + 422500
a² = 672500
a = [tex]\sqrt{672500}[/tex]
a = 820 m
La dirección del desplazamiento resultante es la dirección noreste desde el punto de partida.
When a wave is absorbed by a medium, its energy is transferred to the medium. The energy is most often transformed into thermal energy. What measurement could you make to confirm the transfer and transformation of wave energy?
Answer:
TEMPERATURE
Explanation:
When a wave is absorbed by a material medium, different phenomena occur, but the collisions with the other particles causes the energy to be transformed into internal energy in the atoms and molecules of the material, with TEMPERATURE measurements the increase in the internal energy of the material.

Explanation:
why did earth most likely form into distinct, separate layers? (HELP ASAP PLZ)
Answer:
The stratification of Earth into its geologic layers was brought about by the formation of the Earth's iron core. The iron core was generated by a combination of radioactive decay and gravitation, which raised the temperature enough for molten iron to form. The migration of molten iron to the center of the Earth displaced the less dense materials toward the surface.The early Earth needed lots of energy to trigger the creation of molten iron. Some of this energy came from radioactive decay. Radioactive elements such as uranium and thorium give off heat when they decay. Radioactive elements were present in greater amounts in the early Earth. The radiation emitted by these elements increased the temperature of the Earth by roughly 2,000 degrees Celsius (about 3,600 degrees Fahrenheit).Gravitational forces both helped the iron accumulate in the center of the Earth and helped generate additional temperature. As the early Earth compacted into a planet thanks to gravity, this compaction gave off heat. As a result, gravitational energy helped raise the temperature of the Earth by an additional 1,000 degrees Celsius (about 1,800 degrees Fahrenheit). In turn, this temperature increase helped sustain the presence of molten iron at the Earth's core.
Explanation:
The hotter temperature in the mantle make the tectonic plates to move apart and form distinct layers. Hence, option C is correct.
What is tectonic movement ?The rocky mantle's base is heated by the core of earth . Buoyancy forces attempt to drive the hottest rocks upward when the densest rock near the mantle's bottom becomes slightly less dense than the somewhat cooler rock above it.
Despite being solid, the rock in the mantle can progressively distort like hot wax because of the intense pressure and heat. As a result, the heated rock gradually pushes through the colder rock.
Cooler rock flows downward to occupy the space near to the core as the hot rock rises, where it gets heated and becomes buoyant enough to rise again later. Near the surface of the Earth, the rising hot rock comes into touch with certain cold rocks, emitting heat, cooling, and lead to the tectonic movement.
