Technician A says that a voltage drop on the ground side of a bulb won’t affect its brightness because the electricity has already been used up. Technician B says that a voltage drop is one way to determine if there is unwanted resistance in a circuit. Who is correct?
Answer:
Technician B
Explanation:
For a given circuit current, the voltage drop is an indication of the resistance in the circuit.
If the voltage drop on the ground side of a bulb is unexpectedly high, it means the circuit resistance is unexpectedly high. Technician B is correct.
True or false? if i were to hook up an ac voltage source to a resistor, the voltage drop across the resistor would be in phase with the current in the circuit.

Explanation:
A +7.5% grade meets a horizontal grade on a section of a rural mountainous highway. If the length of the crest vertical curve formed in that section is 300 ft long, determine the safe operating speed on the highway.
Using the formula of comfort condition it is possible to determine the safe operating speed on the highway.
What is a deflection angle?In physics, we define angular deviation as the angle resulting from the deflection of light when reflected from a prism. A prism has the ability to separate white light into several other colors, which are reflected by the object.
The comfort condition formula is given by: [tex]L=2(\frac{NV^{3} }{C} )^{\frac{1}{2} }[/tex]
Where, L is the length of the vertical curve, N is the grade, V is the safe speed operation and assuming the standart value for C (0,6 m/s3) it is possible to calculate:
[tex]C = 0,6 m/s^{3} = 1,968 ft/s^{3}\\ N= N1 - N2 = 7,5-0 = 7,5% = 0,075[/tex]
Changing the values in the formula:
[tex]L=2(\frac{NV^{3} }{C}){\frac{1}{2} } \\300 = 2(\frac{0,075.V^{3} }{1,968})^{\frac{1}{2} } \\V = 83,89 ft/s[/tex]
So, the safe operating speed on the highway is 83,89 ft/s.

How a car break works?
The break system of a car is composed by several items that are always working together to slow down and bring a vehicle to a complete stop. It also has the function of keeping the car stationary when it is parked. In general, this system has two manual activation modes: the lever and the pedal, with the exception of vehicles adapted for people with disabilities.
Most vehicles today use the disc brake system. Disc brakes work by using pads, which are held inside a hydraulic caliper, receiving pressure to brake. Such pads generate friction on a disc, which makes the vehicle stop permanently.
The drum brake is another type, being older and dependent on the famous linings to cause friction in the wheel and stop the vehicle. A hydraulic cylinder makes the plies move inside the drum, which is a hollow part fastened with screws and attached to the wheels. This type of brake is on the rear wheels, for the most common models.

A company is currently paying its employees $0.38 per mile to drive their own cars on company business. The company is considering supplying employees with cars, which would involve purchasing at $25,000 with an estimated three-year life, a net salvage value of $8,000, taxes and insurance at a cost of $900 per year, and operating and maintenance expenses of $0.22 per mile. If the interest rate is 10% and the company anticipates an employee’s annual travel to be 22,000 miles, what is the equivalent cost per mile (neglecting income taxes)?
The equivalent cost per mile is mathematically given as
Equivalent kilometer = 0.61
What is Distance?Distance is a measure of the distance between two places. Depending on context, the term "distance" might refer to a precise measurement or an approximation based on other factors. |AB| can be used to represent the distance between two points.
What is an Equivalent cost per mile?Generally, the equation for Equivalent annual cost is mathematically given as
EAC= $ 25,000 ( A/P, 10% , 3 years ) + $ 900 + $ 0.22 * 22,000 - $ 8000 ( A/F , 10% , 3 years)
Therefore
EAC= $ 25,000 * 0.402115 + $ 5740 - $ 8000 * 0.302115
EAC= $ 13,375.955
In conclusion, the Equivalent cost per kilometer

A______solid-state relay is an electronic device that performs the same function as an electromechanical relay.
Answer: Non-programmable
Explanation:
A non-programmable solid-state relay is an electronic device that performs the same function as an electromechanical relay.
What is a solid-state relay?An SSR is an electrical switching device that turns on or off when an external voltage (AC or DC) is applied across its control terminals. They perform the same job as an electromechanical relay, but because they include no moving parts, they have a longer operational lifetime.
Solid-state relays are the semiconductor analogs of electromechanical relays and can thus control electrical loads. When energized, the solid-state relay is a fairly complex device with a simple purpose: to activate a single output load.
Therefore, a non-programmable solid-state relay is a type of electrical device that functions similarly to an electromechanical relay.

For some alloy, the yield stress is 345-MPa (50,000-psi) and the elastic modulus (E) is 103-GPa (15x106 psi). What is the maximum load that may be applied to a specimen with a cross-sectional area of 130-mm2 (0.2-in2) without plastic deformation
The maximum load that may be applied to a specimen with a cross-sectional area of 130 mm² is; 35535 N
How to find Elastic Modulus?We are told that for an alloy, the yield stress is 345-MPa and the elastic modulus (E) is 103-GPa.
Now, we want to find the maximum load that may be applied to a specimen with a cross-sectional area of 130-mm² without plastic deformation. Thus;
We are given the parameters;
Yield Stress; σ = 345 Mpa = 345 * 10⁶ Pa
Elastic Modulus; E = 103 GPa = 103 * 10⁹ Pa
Cross sectional Area; A = 130 mm² = 103 * 10⁻⁶ m²
Formula for stress without Plastic deformation is;
σ = F_max/Area
where;
σ is stress
F_max is maximum force
Area is Area
Thus making maximum force the subject of the formula gives;
F_max = σ * A
Plugging in the relevant values for stress and area gives us;
F_max = 345 * 10⁶ * 103 * 10⁻⁶
F_max = 35535 N
The maximum load that may be applied to a specimen with a cross-sectional area of 130 mm² is gotten to be 35535 N

Determine the carburizing time necessary to achieve a carbon concentration of 0.30 wt.% at a position of 4 mm into an iron-carbon alloy that initially contains 0.10 wt.% C. The surface concentration is to be maintained at 0.90 wt.% C, and the treatment is to be conducted at C. Use the diffusion data for -Fe in Table 5.2
The carburizing time necessary to achieve a carbon concentration is 31.35 hours
How to find the Carburizing Time?To determine the carburizing time necessary to achieve the given carbon concentration, we will use the equation:
(Cs - Cx)/(Cs - C0) = ERF(x/2√Dt)
where;
Cs is Concentration of carbon at surface = 0.90
Cx is Concentration of carbon at distance x = 0.30
Distance x = 4 mm = 0.004 m
C0 is Initial concentration of carbon = 0.10
ERF() = Error function at the given value
D = Diffusion of Carbon into steel
t = Time necessary to achieve given carbon concentration ,
Thus, plugging in the relevant values gives;
(Cs - Cx)/(Cs - C0) = (0.9 - 0.3)/(0.9 - 0.1)
= 0.6/0.8 = 0.75
now, ERF(z) = 0.75 and as such using ERF table, we can say that;
Z = 0.814. Thus;
(x/2√Dt) = 0.81
Using the table of diffusion data, we have;
At a temperature of (1100°C) or 1373 K, we have;
D = 5.35 × 10⁻¹¹ m²/sec.
Calculating the carbonizing time by using the equation z = (x/2√Dt);
where;
t is carbonizing time
Thus;
0.814 = (0.004/(2 × √5.35 × 10⁻¹¹ × √t))
0.814 = 0.004 /(1.4628 × 10⁻⁵ × √t)
0.814 × 1.4628 × 10⁻⁵ × √t = 0.004
1.19072 × 10⁻⁵ × √t = 0.004
√t = 0.004/(1.19072 × 10⁻⁵)
√t = 335.93
t = 112848.96 seconds
Converting to hours gives;
t = 112848.96/3600
t = 31.35 hours
Therefore, the carburizing time necessary to achieve a carbon concentration is 31.35 hours
