Which of the following best describes how a transformer works?
O A. Converts electric energy into mechanical energy
B. Converts the voltage of a current source
C. Converts mechanical energy into electrical energy
D. Converts the direction of current flow in a circuit

Answers

Answer 1

Answer:

B.Converts the voltage of a current source

A transformer is an electrical apparatus designed to convert alternating current from one voltage to another. It can be designed to "step up" or "step down" voltages and works on the magnetic induction principle. ... When voltage is introduced to one coil, called the primary, it magnetizes the iron core.

Many scientific discoveries are made by chance. While studying one phenomenon, a scientist may discover a different one. Such was the case when William Herschel discovered the planet Uranus in 1781. Herschel was charting faint stars in the sky, when he discovered something that was not a star. How can astronomers tell the difference between a star and a planet

Answers

Answer:

One simple explanation is that planets move, while stars remained fixed in the sky. You can observe a planet's orbit, but a star will stay in the same position.

Explanation:

Stars emit their own light due to thermonuclear fusion while planets have fixed orbits and they do not have their own light.

What are the differences between a planet and a star?

A star can be described as an astronomical body that possesses a light that causes it to reflect the light. A planet can be described as a fixed celestial body with a fixed path that spins on its own axis and reflects the light from an external source. Planets do not have an internal light source and receive light from external sources such as the Sun.

Stars have incredibly hot high temperatures while planets have relatively low temperatures. Stars produce their own light but planets are incapable of producing their own light.

Stars exhibit the unique effect of twinkling in the sky while planets do not exhibit the twinkling effect. The position of stars changes but can be seen only after a long time while planets in orbits change their positions constantly.

A 15.0 kg crate, initially at rest, slides down a ramp 2.0 m long and inclined at an angle of 20.0° with the horizontal. Using the work-kinetic energy theorem and disregarding friction, find the
velocity of the crate at the bottom of the ramp. (g = 9.81 m/s?)

Answers

The component of the crate's weight that is parallel to the ramp is the only force that acts in the direction of the crate's displacement. This component has a magnitude of

F = mg sin(20.0°) = (15.0 kg) (9.81 m/s^2) sin(20.0°) ≈ 50.3 N

Then the work done by this force on the crate as it slides down the ramp is

W = F d = (50.3 N) (2.0 m) ≈ 101 J

The work-energy theorem says that the total work done on the crate is equal to the change in its kinetic energy. Since it starts at rest, its initial kinetic energy is 0, so

W = K = 1/2 mv ^2

Solve for v :

v = √(2W/m) = √(2 (101 J) / (2.0 m)) ≈ 10.0 m/s

A standing wave measures 12 m between its first and fourth node and its frequency 325 Hz. What is the standing wave's speed?
1300 m/s
380 m/s
1500 m/s
750 m/s

Answers

Answer:

1300 m/s

Explanation:

Applying,

v = λf/2............... Equation 1

Where v = velocity or speed of wave, f = frequency of wave, λ = wavelength of wave.

From the question,

Given: f = 325 Hz, λ = (12×2/3) = 8 m

Substitute these values into equation 2

v = 325(8)/2

v = 1300 m/s.

Hence the standing wave speed is 1300 m/s

The right option is 1300 m/s

the

Answers

Answer:

See the answer below

Explanation:

Acceleration due to gravity (g) is the accelerational force experienced by a body as a result of the influence of the earth's gravitational force. It is a vector quantity, that is, it has both magnitude and direction.

The acceleration due to gravity is inversely proportional to the square of the radius of the earth. Hence, g at the equatorial region is slightly lesser (9.780 m/s2) than that of the polar regions (9.832 m/s2) of the earth because the earth bulges at the equator leading to a higher radius than at the poles.

An organism that is only one cell big and has a nucleus is most likely a member of which kingdom?

Answers

Answer:

Protista

Explanation:

Taxonomy can be defined as the process of naming, classification and description of living organisms such as plants and animals. Thus, the biological classification of living organisms based on similarities or characteristics such as eyes, number of legs, etc., is generally referred to as taxonomy.

Basically, taxonomy helps scientist to have a good understanding and knowledge when studying various organisms.

Furthermore, the eight (8) biological classification (taxonomy) used for grouping and organizing organisms are; kingdom, domain, phylum, family, order, class, species and genus.

An organism that has only one cell, big and has a nucleus is most likely a member of Protista. Thus, a Protista such as euglena, paramecium, amoeba, etc., have a nucleus and are unicellular.

A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

What is potential difference?

The difference in charge carriers' energy between two places in a circuit is known as the potential difference.

Voltage is another name for potential difference (p.d.), which is expressed in volts (V). When charge carriers move through electrical components in a circuit, energy is delivered to those parts. To determine the potential difference, we use a voltmeter (or voltage).

The amount of current multiplied by the resistance equals the potential difference, which is the same as voltage. One Coulomb of charge uses one Joule of energy to move between two points in a circuit, which is equal to a potential difference of one Volt.

Therefore, Potential difference is measured in joules​ is true statement.

Answers

Answer:

Supongo que queremos determinar la carga de la carga de prueba.

Sabemos que la fuerza culombiana entre dos cargas q₁ y q₂, separadas por una distancia R, está dada por:

[tex]F = k_c*\frac{|q_1*q_2|}{R^2}[/tex]

Aislandolo para una de las cargas, obtenemos:

[tex]\frac{F*R^2}{kc*|q_1|} =|q_2|[/tex]

En este caso sabemos:

fuerza atractiva, por lo que los signos de las cargas son opuestos.

q₁  = 5 mC

R = 35cm

F = 1.5 N

Kc = 9*10^9 N*m^2/C^2

Un primer paso, seria reescribir todos los valores en las mismas unidades.

Sabiendo que:

100cm = 1m

R = 35cm = (35/100) m = 0.35m

Y sabiendo que:

1mc = 1*10^(-6) C

Entonces:

q₁  = 5 mC = 5*1*10^(-6) C = 5*10^(-6) C

Ahora podemos reemplazar esos valores en la ecuación de la fuerza, para obtener el valor de la otra carga:

[tex]\frac{15N*(0.35m)^2}{(9*10^9 N*m^2/C^2)*5*10^{-6}C} =|q_2| = 4.08*10^{-5} C[/tex]

Y recordar que las cargas tienen signo opuesto, entonces la carga de la carga de prueba es:

q₂ = -4.08*10^-5 C
