When starting your vehicle, what does it mean when the ABS indicator light 1 point

Bezzdna [24]

Answer:

C. The vehicle safety check indicates the ABS is functioning normally.

Explanation:

ABS, an antilock braking system, is a safe and secure slip-resistant braking system in cars and air-crafts. <u>An ABS is there to prevent wheel-locking while using brakes in vehicles</u>.

When one ignites a car, the ABS indicator will light up briefly as a part of safety check.<em> The ABS indicator light comes on for a few seconds before it turns off again. This indicates that the ABS system is functioning normally</em>. But, if the ABS indicator light remains after turning on the ignition, this indicates that there is a problem in the system.

In the given scenario, the ABS indicator is functioning properly, thus the correct answer is the third option (C).

Dos capacitores de placas paralelas, idénticos, pero con la excepción de que uno tiene el doble de separación entre sus placas q

Charra [1.4K]

Las características de la capacitancia permiten encontrar los resultados para las diferentes preguntas

1) El capacitor con menor distancia entre las placas tiene mayor campo eléctrico.

2) El capacitor con menor distancia tiene mayor carga

3) El capacitor con menor distancia tiene mayor densidad de carga

Los capacitores son sistema que sirve para acumular carga, esa formado por placas conductoras separadas una distancia pequeña, la capacitancia es

$C = \frac{Q}{DV} = \frac{\epsilon_o A}{d}$

Donde Q es a carga, ΔV la diferencia de potencial, A el area y d la separación de las placas.

Busquemos las respuestas para las diferentes preguntas:

1) Cual tiene mayor campo eléctrico.

El potencial y el campo eléctrico están relacionados

ΔV = - E d

E = - $\frac{\Delta V}{d}$

Indican que un capacitor tiene el doble de separación de las placas que el otro

Capacitor 1

E = $- \frac{\Delta V}{d_1}$

Capacitor 2

d₂ = 2 d₁

E₂ = $- \frac{\Delta V}{2d_1}$

E₂= ½ E₁

Por lo tanto el capacitor con menor distancia entre las placas tiene mayor campo eléctrico.

2) Cual tiene mas carga

Busquemos la carga para cada capacitor

Q = ε₀ $\frac{A \Delta V}{d}$

Capacitor 1

Q₁ = (ε₀ A ΔV) $\frac{1}{d_1}$

Capacitor 2

Q₂ = (ε₀ A Δv) $\frac{1}{2d_1}$

Q₂ = Q₁/2

El capacitor con menor distancia tiene mayor carga

3) Cual tiene mayor densidad de energía

La densidad de energía en un capacitor esta dada por

$u_E$ = ½ ε₀ E²

calculamos para cada capacitor

Capacitor 1

$u_{E\ 1}$ = ½ ε₀ E₁²

Capacitor 2

$u_{E 2}$ = ½ ε₀ (E₁/2)²

por lo cual el capacitor con menor distancia tiene mas densidad de carga

En conclusión con lass característica de capacitancia podemos encontrar los resultados para las diferentes preguntas

1) El capacitor con menor distancia entre las placas tiene mayor campo eléctrico.

2) El capacitor con menor distancia tiene mayor carga

3) El capacitor con menor distancia tiene mas densidad de carga

If a pilot-operated check valve (POC) does not check flow, you will see

Elan Coil [88]

if a pilot-operated check valve (POC) does not check flow, you will see The symptoms and symptoms of a failing swing test valve are regularly audible.

<h3>What happens when the pilot valve reaches set strain?</h3>

When the pilot valve reaches set strain it opens and releases the strain from the dome. The piston is then unfastened to open and the principle valve exhausts the machine fluid. The manage pilot opens both to the principle valve exhaust pipe or to the atmosphere.

Pilot operated test valves paintings through permitting unfastened go with the drift from the inlet port thru the opening port. Supplying a pilot strain to the pilot port permits go with the drift withinside the contrary direction. Air strain on the pinnacle of the poppet meeting opens the seal permitting air to go with the drift freely.

Stels [109]

Answer:

Technician B is correct.

Explanation:

Two technicians are discussing the a series-parallel brake lamp circuit that does not illuminate.

The statement made by Technician A saying that an open in one of the parallel branches could be the cause has no ground because an opening in any branches has not to do with the issue since there is no disconnection The statement made by Technician B saying that a shorted (or stuck closed) brake lamp switch wired in series could be the cause is correct.
