Explain why there is a voltage between the two terminals of the secondary coil

Answers

Answer 1

Answer:

The coils are not electrically connected. ... the primary coil current produces a magnetic field, which changes as the current changes. the iron core increases the strength of the magnetic field. the changing magnetic field induces a changing potential difference (voltage) in the secondary coil.

Answer 2

There is a voltage between the two terminals of the secondary coil because the magnetic field/magnetic flux is strengthened by the iron core. The secondary coil's potential difference (voltage) changes as the magnetic field changes. Energy is transferred by law of conversation .

What is magnetic flux?

Magnetic flux is the number of magnetic field lines passing through a closed surface.

What is electromagnetic induction?

There is a change in magnetic flux associated with a coil it gives rise to an induced current and hence an induced EMF in the coil. This phenomenon is called electromagnetic induction.

What is law of conservation of energy?

Law of conservation of energy states that energy can neither be created nor be destroyed . It can only be converted from one form to another form.

Lamar writes several equations trying to better understand potential energy. What conclusion is best supported by lamar's worm?

Answers

Complete question is;

Lamar writes several equations trying to better understand potential energy. What conclusion is best supported by Lamar’s work?

A) The elastic potential energy is the same for any distance from a reference point.

B) The gravitational potential energy equals the work needed to lift the object.

C) The gravitational potential energy is the same for any distance from a reference point.

D) The elastic potential energy equals the work needed to stretch the object

Answer:

B) The gravitational potential energy equals the work needed to lift the object.

Explanation:

In physics, we know that potential energy is the energy of a body at rest while the energy of a body in motion is known as kinetic energy.

However,the work required to lift a body from it's position of rest is equal to the Gravitational potential energy of that body.

Elastic potential energy is the one that is stored as a result of force applied to deform an elastic object. Thus, it is not equal to the work needed to stretch the object and it is also not the same for any distance from reference point.

Thus, looking at the options, Option B is correct

Explanation:

Un automóvil viaja a la velocidad de 10 m/s. Se acelera Durante 12s y aumenta su velocidad hasta 70 m/s ¿Que aceleración experimenta el automóvil?

Answers

Answer:

Aceleracion = 5 m/s²

Explanation:

Dados los siguientes datos;

Velocidad inicial = 10 m/s

Velocidad final = 70 m/s

Tiempo, t = 12 segundos

Para encontrar la aceleración;

Aceleración se puede definir como la tasa de cambio de la velocidad de un objeto con respecto al tiempo.

Esto simplemente significa que la aceleración viene dada por la resta de la velocidad inicial de la velocidad final a lo largo del tiempo.

Por lo tanto, si restamos la velocidad inicial de la velocidad final y la dividimos por el tiempo, podemos calcular la aceleración de un objeto. Matemáticamente, la aceleración viene dada por la fórmula;

[tex] Aceleracion = \frac{final \; velocidad - inicial \; velocidad}{tiempo}[/tex]

Sustituyendo en la fórmula, tenemos;

[tex] Aceleracion = \frac{70 - 10}{12}[/tex]

[tex] Aceleracion = \frac{60}{12}[/tex]

Aceleracion = 5 m/s²

How is atomic energy is produced ?​

Answers

Answer:

Fission and Fusion

Explanation:

There are two basic processes: fission and fusion. In both processes, mass is converted to energy according to the famous equation, e=mc2

In fission, heavy fuel (isotopes of uranium, plutonium, thorium, etc.) atoms split, releasing kinetic energy daughter particles and as radiation. In a reactor plant kinetic energy of the daughter particles is converted to thermal energy as the particles are slowed by the fuel matrix or primary coolant. Radiation is absorbed by various components of the reactor and converted to thermal energy. Thermal energy from both sources is then carried out of the reactor core by primary coolant to a turbine where it is converted to electrical energy which is then transmitted to the power grid.

In fusion, light atoms of hydrogen combine to form helium. Energy released from this reaction will be captured and used to generate electricity as well, once we have constructed a fusion reactor large enough to be self-sustaining (i.e. produce as much or more energy from fusion than needed to start the reaction going).

In the case of nuclear weapons, the tremendous energy from the nearly simultaneous fission/fusion reactions is used to create a fireball, intense radiation, and a large shock wave.

Q7) A box sliding with a velocity of 5 m/s accelerates at 2 m/s^2. How
much is the box displacement after 6 s?

Answers

Answer:

The box displacement after 6 seconds is 66 meters.

Explanation:

Let suppose that velocity given in statement represents the initial velocity of the box and, likewise, the box accelerates at constant rate. Then, the displacement of the object ([tex]\Delta s[/tex]), in meters, can be determined by the following expression:

[tex]\Delta s = v_{o}\cdot t+\frac{1}{2}\cdot a\cdot t^{2}[/tex] (1)

Where:

[tex]v_{o}[/tex] - Initial velocity, in meters per second.

[tex]t[/tex] - Time, in seconds.

[tex]a[/tex] - Acceleration, in meters per square second.

If we know that [tex]v_{o} = 5\,\frac{m}{s}[/tex], [tex]t = 6\,s[/tex] and [tex]a = 2\,\frac{m}{s^{2}}[/tex], then the box displacement after 6 seconds is:

[tex]\Delta s = 66\,m[/tex]

The box displacement after 6 seconds is 66 meters.

What is the equivalent resistance of a circuit that contains four 75.0 resistors connected in parallel with a 100.0 V battery?

Answers

Answer:

18.75 ohms.

Explanation:

From the question,

]When four resistors are connected in parallel in a circuit,

The equilvalent resistor is given as

1/R' = 1/R₁+1/R₂+1/R₃+1/R₄............................Equation 1

Where R' = Equivalent resistor.

Given: R₁ = R₂ = R₃ = R₄ = 75.0 ohms.

Substitute these values into equation 1

1/R' = (1/75)+(1/75)+(1/75)+(1/75)

1/R' = 4/75

R' = 75/4

R' = 18.75 ohms.

Hence the equivalent resistance = 18.75 ohms.

18.8 ohms
