Answer:

False, metal and dirt ARE considered contaminants!

Explanation:

i ride motocross! trust me!

The statement "Metal and dirt are not considered contaminants to oil" is false. The correct option is B.

Metals are chemical elements that have high thermal and electrical conductivity, and they are soft and ductile. Magnesium, helium, gold, and silver are metals. They are very reactive, and they contain both gas and solids.

Oil and dirt are considered contaminated to oil. It causes a chemical reaction in the oil, that's why it is a problem with contamination of the oil. It causes reactions like depletion or oxidation.

In motor oils, there are many chances of pollution with dirt and metals, and other oxides. This causes debris and leads to degradation of work of lubrication of engine parts, which causes friction.

Thus, the statement is true. The correct option is B.

Answer:

E = 132.69 sin(ωt -11.56)

i(t) = 6.64 sin (ωt +48.44) A

Explanation:

given data

e1 = 80 sin ωt volts                       80 < 0

e2 = 60 sin (ωt + π/2) volts          60 < 90

e3 = 100 sin (ωt – π/3) volts        100 < -60

solution

resultant will be  = e2 + e2 + e3

E =  80 < 0 + 60 < 90 + 100 < -60

\(\bar E\) = 80 + j60 + 50 - j50\(\sqrt{3}\)

\(\bar E\) = 130 + (-j26.60)

\(\bar E\) = 132.69  that is less than -11.56

so

E = 132.69 sin(ωt -11.56)

and

as we have given the impedance

z = (10-j17.3)Ω

z = 19.982 < -60

and

i(t) = \(\frac{132.69}{19.982}\) sin(ωt -11.56 + 60)  

i(t) = 6.64 sin (ωt +48.44) A

Answer:

The resistance of a cell membrane rises when an ion channel opens, whereas conductance falls.

Describe resistance.

The ability to avoid or lessen the presence of illnesses in otherwise intermediate hosts is known as disease resistance. It can be caused by environmental or genetic causes, like inadequate penetrance. [1] Disease intolerance is distinct since it refers to the a host's ability to manage the negative effects of a disease on that host's health. This in crops includes plant pathogens tolerance and can be inherited gene for gene. Some plants may withstand the presence of numerous insects without suffering any serious consequences. However, this is not particularly acceptable because bugs will still cause damage, and in fact, support is given to additional breeding and population growth of the pest species.

t_ds = 0:1/8000:0.001;

Sensors in a vehicle with a side sonar system are typically located on the side bumpers or door panels. They are evenly distributed along the length of the vehicle for effective detection.

A side sonar system in a vehicle is designed to detect obstacles and other objects near the sides of the car during maneuvers such as parking or changing lanes. To ensure comprehensive coverage, multiple sensors are embedded along the side bumpers or door panels.

These sensors emit ultrasonic waves that bounce off nearby objects and return to the sensors, allowing the system to calculate the distance to the detected object. This information is then relayed to the driver through visual or auditory cues, helping them make safe driving decisions. The precise location of sensors may vary depending on the vehicle make and model.

The unknown capacitor in arm CD must have a value of 330 microfarads, and the unknown resistor must have a value of 100 kilo-ohms.

To solve the problem, use the following formula:
Cseries = C1 x C2 / (C1 + C2)

Where C1 is the value of the capacitor in arm AB (47 microfarads) and C2 is the value of the capacitor in arm BC (330 microfarads).

Therefore, Cseries = 330 microfarads.

Also, the total resistance of arms CD is the sum of the resistance of the resistor (R) and the reciprocal of the capacitive reactance of the capacitor (1/Xc).

Using the following formula:
Rtotal = R + 1/Xc

Where Xc = 1/2πfC,

f is the frequency and C is the capacitance.

For this problem,

Xc = 1/2π(50)(330 x 10-6)

Here is the answer: The answer is Technician B is correct because the unequal length driveshafts may cause a pull during hard acceleration called torque steer. In FWD vehicles, unequal length front driveshafts are called half shafts. Half shafts are used in FWD (front-wheel drive) systems to transfer power from the engine/transaxle to the front wheels to make them spin.

Explanation:

Answer:

La potencia disipada por el resistor es 200 watts.

Explanation:

Supóngase que el resistor trabaja en corriente continua (CC). La potencia disipada por el resistor (\(\dot W\)), medida en watts, es definida por la siguiente ecuación matemática:

\(\dot W = i^{2}\cdot R\) (1)

Donde:

\(i\) - Corriente eléctrica, medida en amperios.

\(R\) - Resistencia eléctrica, medida en ohms.

Si sabemos que \(R = 10000\,\Omega\) y \(i = 20\times 10^{-3}\,A\), la potencia disipada por el resistor es:

\(\dot W = (20\times 10^{-3}\,A)\cdot (10000\,\Omega)\)

\(\dot W = 200\,W\)

La potencia disipada por el resistor es 200 watts.

Centrifugal force is the force exerted on an object moving in a circular path and directed outward from the center. In order to determine the centrifugal force in pound-force of a centrifuge carrying 50mL of blood, we will need to use the formula for centripetal force:

Centrifugal force = (mass x acceleration)/radius

Here's how to solve the problem:

First, we need to determine the mass of the blood being carried by the centrifuge. We know the volume of blood (50 mL) and the density of blood (0.994 g/mL), so we can use the formula:

mass = volume x density

mass = 50 mL x 0.994 g/mL

mass = 49.7 g

Next, we need to convert the given units to SI units (meters and seconds):

Centripetal acceleration = 64 ft/s^2
1 ft = 0.3048 m
Centripetal acceleration = 64 ft/s^2 x 0.3048 m/ft = 19.5072 m/s^2

Rotational speed = 345 rpm
1 rpm = 1/60 s
Rotational speed = 345 rpm x 1/60 s = 5.75 s^-1

Now we can use the formula to calculate centrifugal force:

Centrifugal force = (mass x acceleration)/radius

The radius of the centrifuge is half the diameter (3.5 inches or 0.0889 meters):

Centrifugal force = (49.7 g x 19.5072 m/s^2)/0.0889 m

Centrifugal force = 10,879.52 N

Finally, we need to convert Newtons to pound-force:

1 N = 0.22481 lb-f
Centrifugal force = 10,879.52 N x 0.22481 lb-f/N

Centrifugal force = 2,442.69 lb-f

Therefore, the centrifugal force in pound-force is 2,442.69 lb-f.

The correct option for the implication of low variety is B) Flexibility needed. Variety refers to the number of different products, services, or activities that an organization offers. High variety means that a company offers a wide variety of products or services, while low variety means that a company provides a limited range of products or services.

One of the implications of low variety is that customers have limited options. They are restricted to purchasing only those goods and services that the company offers, which may not match their requirements or preferences. This may lead to losing customers to rivals who offer a greater variety of goods and services.

In the case of low variety, it is critical to have the required flexibility. Customers may ask for certain specific goods or services that are not provided by the company. To meet customer requirements, the company should be adaptable and able to rapidly respond to customer requests by expanding its product line. As a result, low variety necessitates the need for flexibility.

The other given options are not valid. Low unit cost is not related to low variety. Unit cost may be affected by economies of scale and other factors, but it is not directly related to variety. High complexity is not related to low variety as well. As the range of goods and services offered by the company increases, the complexity of the company's operations and management also increases. Matching customers' specific needs is partially correct because the company cannot match customer specific needs in low variety. In low variety, the company has a limited range of goods and services, so it is not possible to fulfill all the customers’ specific needs.
