Which circuit prevents the flow of current?

2 answers:

5 0

The answer is Open Circuit. Open Circuit is a circuit that has a break that prevents the flow of current; a circuit with a gap that stops the current. An "open<span>" (off) switch leave gaps in a </span>circuit<span> preventing electrons from traveling from one side of the power source to the other. Thus, electrons will not flow. This situation is called an </span>open circuit<span>.</span>

Como anticipan la caída del proyectil, con movimiento parabólico para que el misil no haga daño

Elena L [17]

Answer:

Conociendo la velocidad inicial del proyectil y el angulo de lanzamiento con respecto ala horizontal.

Explanation:

Para poder anticipar la caída del proyectil es importante conocer la velocidad inicial del proyectil y el angulo de disparo del proyectil con respecto a la horizontal.

A continuación se presenta un diagrama o esquema donde se pueden ver estas variables y se explicaran a la brevedad:

Para poder encontrar el rango que es la máxima distancia horizontal recorrida por el proyectil debemos utilizar la siguiente ecuación:

$x=(v_{o})_{x} *t\\where:\\(v_{o})_{x} = velocidad inicial x-component [m/s]\\t= time [s]$

Para poder encontrar el tiempo debemos utilizar la siguiente ecuación:

$y=(v_{y} )_{o}*t-0.5*g*t^{2} \\donde:\\(v_{y} )_{o}= velocidad inicial componente y [m/s]\\g = gravity = 9.81 [m/s^2]\\t = time [s]$

En la anterior ecuación, igualamos y = 0, ya que cuando el proyectil cae al suelo la distancia vertical es cero. De esta manera podemos encontrar el tiempo t, ya que conocemos la velocidad inicial del proyectil en la componente y.

Seguidamente reemplazamos t en la primera ecuacion y encontramos la distancia x o el rango.

When discharging, what percentage of the starting voltage will the capacitor reach after 5rc?

Ahat [919]

When discharging equivalent of 0% starting voltage will the capacitor reach after 5RC.

V(t) = V0e-t/RC = V0b initially.

<h3>What is capacitor?</h3>

In an electric field, a capacitor is a device that stores electrical energy. It has two terminals and is a passive electrical component.

Capacitance refers to a capacitor's effect.
The terminals in a capacitor are connected to two metal plates that are spaced apart by a dielectric, a non-conducting material.
Two pieces of aluminum foil, along with a piece of paper, can be used to create a capacitor (and some electrical clips).
It won't have a lot of storage capacity, so it won't be a great capacitor, but it will still function.

<h3>What are the different types of capacitors?</h3>

The numerous kinds of capacitors and their applications.

Frequently utilized in radio tuning circuits is air.

Mylar: The material most frequently used in timer circuits for clocks, alarms, and counting.

Good for high-voltage applications is glass.

Ceramic is used in X-ray, MRI, and other high-frequency devices.

a powerful capacitor fuels hybrid and electric vehicles.

Which of the following are true statements? A. Like charges repel B. Unlike charges repel C. Unlike charges attract or D. Charge

Brums [2.3K]

Answer: The correct answers are (A) and (C).

Explanation:

The expression from electrostatic force is as follows;

$F=\frac{kq_{1}q_{1}}{r^{2} }$

Here, F is the electrostatic force, k is constant, r is the distance between the charges and $q_{1},q_{1}$ are the charges.

The electrostatic force follows inverse square law. It is inversely proportional to the square of the distance between the charges. It is directly proportional to the product of the charges.

Like charges repel each other. There is a force of electrostatic repulsion between the like charges. Unlike charges attract each other. There is a force of electrostatic attraction between unlike charges.

The charges are induced on the neutral object when it is placed nearby the charged object without actually touching it.

Therefore, the true statements from the given options are as follows;

Like charges repel.

Unlike charges attract.

Some cities now implement signal lights designed to specifically apply to _____ rather than motorized vehicles.

dimulka [17.4K]

The correct answer is C; Bicycles.

Further Explanation:

In major cities, in the United States, have implemented signal lights specifically designed for bicycle riders. The riders also have their own designated bike lanes in many large cities. Drivers in vehicles, are to give the right of way to people on bicycles.

Bicycle riders are to follow the same laws and laws specifically for the riders or they can face fines and tickets.
