Technician A says that relays can fail because the relay winding is open. Technician A is correct.

<h3>What is winding?</h3>

A single turn of the wound material, which is material wrapped or coiled around an object.

Poor contact alignment and open coils can also cause relays to malfunction.

The most important aspect impacting relay dependability is choosing the right relay type for a particular application. When incorporating them into circuits, several subpar design techniques are employed.

Hence, technician A is correct.

To learn more about the winding refer;

A sand has a natural water content of 5% and bulk unit weight of 18.0 kN/m3. The void ratios corresponding to the densest and lo
Zinaida [17]

Answer:

Relative density = 0.545

Degree of saturation = 24.77%

Explanation:

Data provided in the question:

Water content, w = 5%

Bulk unit weight = 18.0 kN/m³

Void ratio in the densest state, e_{min} = 0.51

Void ratio in the loosest state, e_{max} = 0.87

Now,

Dry density, \gamma_d=\frac{\gamma_t}{1+w}

=\frac{18}{1+0.05}

= 17.14 kN/m³

Also,

\gamma_d=\frac{G\gamma_w}{1+e}

here, G = Specific gravity = 2.7 for sand

17.14=\frac{2.7\times9.81}{1+e}

or

e = 0.545

Relative density = \frac{e_{max}-e}{e_{max}-e_{min}}

= \frac{0.87-0.545}{0.87-0.51}

= 0.902

Also,

Se = wG

here,

S is the degree of saturation

therefore,

S(0.545) = (0.05)()2.7

or

S = 0.2477

or

S = 0.2477 × 100% = 24.77%

Describe the Optical Fiber Network( i need 2 paragraphs, but give me about 5 sentences or like 3)
frez [133]

Answer: Fiber Optic Network Fiber-optic networks have been used for decades to transmit large volumes of traffic across the country. The economics of fiber networks have only recently allowed for connecting the fiber directly to the home, creating a fiber-to-the-home (FTTH) network.

A disk is rotating around an axis located at its center. The angular velocity is 0.5 rad/s. The radius of the disk is 0.4 m. Wha
dimaraw [331]

Answer:

0.2 m/s

Explanation:

The velocity of a point on the edge of a disk rotating disk can be calculated as:

v=\omega*r

Where \omega is the angular velocity and r the radius of the disk. This leads to:

v=0.5\,rad/s\,*\,0.4\,m=0.2\,m/s

Find the cost of fencing a rectangular park of length 10 m and breadth 5 m at the rate of? 10 per metre.
ser-zykov [4K]
It costs 300
Perimeter = 2(L+B)
2(10+5)
2(15) = 30
10 — 1metre
X — 30metres
30metres = 300

Hope that helps :)

DanielleElmas [232]

Answer:

Both Tech A and B are correct

Explanation:

One the three method of turning off the MIL is when Vehicle drive on 3 consecutive trips with warm-up cycle without detecting fault. So, with this statement, Tech A is correct.

The MIL will be acrivated when DTC stored in memory and so, the Tech B is also correct.
