given the function: g(a,b,c) = bc ac ab using shannon's expansion theorem, what is (are) the cofactor(s) of g with respect to !c? (do not reduce the cofactors).

Answer:

  Vab = 80V

Explanation:

The only current flowing in the circuit is supplied by the 100 V source. Its only load is the 40+60 ohm series circuit attached, so the current in that loop is (100V)/(40+60Ω) = 1A. That means V1 = (1A)(60Ω) = 60V.

Vab will be the sum of voltages around the right-side "loop" between terminals 'a' and 'b'. It is (working clockwise from terminal 'b') ...

  Vab = -10V +60V +(0A×10Ω) +30V

  Vab = 80V

r² = 3.6924

r = √3.6924

r = 1.922 mm

Answer:

Δ enthalpy = -23 Btu/Ibm

Explanation:

Given data:

Pressure ( P1 ) = 250 psi

Initial Temperature ( T1 ) = 175°F

Final temperature ( T2 ) = 20°F

Calculate the change in the enthalpy of R-134a

From R-134 table

h1 = 129.85 Btu/Ibm

s1 = 0.23281 Btu/Ibm.R

note : entropy is constant  

hence ; s1 = s2

by interpolation  ; h2 = 106.95

Δ enthalpy = h2 - h1

                  =  ( 106.95 - 129.85 ) = -23 Btu/Ibm

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.

In the LP formulation of a maximal flow problem, the statement that a conservation of flow constraint ensures that an arc's flow capacity is not exceeded is false.

In the maximal flow problem, there are two main types of constraints:

1. Conservation of flow constraints: These constraints ensure that the flow into a node equals the flow out of the node, except for the source and sink nodes. They ensure the flow conservation at each node.

2. Capacity constraints: These constraints ensure that the flow through an arc does not exceed its capacity. They are responsible for limiting the flow within the arc's capacity.

So, in summary, the conservation of flow constraint ensures that the flow into and out of each node is balanced, while the flow capacity constraint ensures that the flow on each arc does not exceed its capacity.

Answer: it spread by winds has a strong effect on fire behavior due to the fanning effect on the fire.Wind increases the supply of oxygen.

Explanation:

Fires need three things to occur in order to start and grow: oxygen, a spark/heat, and fuel. Wildfires in forests have plenty of fuel and heat is never really an issue, therefore the wind can cause a fire to continue and even spread faster. Wind will not only increase the fire's supply of oxygen, but it will   also blow the fire in many different directions, now causing the flames to spread.

To determine the heat transfer rate per unit length from the fluid in the tube to the surroundings, we need to calculate the thermal resistance of each layer and then use them in the overall heat transfer equation.

The thermal resistance of the tube therefore, he thermal resistance of the insulation can be calculated using the equation. where Lin is the natural logarithmic mean radius and kin is the thermal conductivity of the insulation material. Lin can be calculated using the formula.

This is because the heat loss through convection and radiation from the outer surface of the insulation layer becomes significant, and the additional insulation reduces this heat loss. Therefore, there exists a critical insulation thickness below which the heat transfer rate actually increases. The plot of heat transfer rate as a function of insulation thickness is shown below.

Answer:

Brainlist me if it helps!

Explanation:

To find the motor speed at the given load, we need to use the following equation:

speed (rpm) = (V - Ia * Ra) / (k * Ea)

where V is the applied voltage, Ia is the armature current, Ra is the armature resistance, k is the motor's torque constant, and Ea is the back EMF.

At no-load, the back EMF is equal to the applied voltage, so we can rearrange the equation to solve for Ea:

Ea = V - Ia * Ra

Substituting the given values, we find that Ea = 230 V - 7 A * 0.05 22 = 229.75 V.

Now we can use the equation to solve for the motor speed at the given load:

speed (rpm) = (230 V - 46 A * 0.05 22) / (k * 229.75 V)

We don't know the value of k, so we'll need to solve for it first. We can use the following equation:

k = (Ea2 - Ea1) / (Ia2 - Ia1)

where Ea2 and Ia2 are the back EMF and armature current at the given load, and Ea1 and Ia1 are the back EMF and armature current at no-load.

Substituting the given values, we find that k = (229.75 V - 0 V) / (46 A - 7 A) = 4.95 V/A.

Substituting this value into the equation for speed, we find that the motor speed at the given load is:

speed (rpm) = (230 V - 46 A * 0.05 22) / (4.95 V/A * 229.75 V) = 890 rpm

(a) The motor speed at the given load is 890 rpm.

(b) The rotational losses are equal to the power consumed by the motor at no-load, which is equal to the product of the applied voltage and the armature current. Substituting the given values, we find that the rotational losses are equal to 230 V * 7 A = 1610 W.

The core losses are equal to the power consumed by the motor at the given load, minus the rotational losses. Substituting the given values, we find that the core losses are equal to 46 A * 230 V - 1610 W = 4140 W - 1610 W = 2530 W.

(c) The efficiency is equal to the output power, divided by the input power. The output power is equal to the power consumed by the motor at the given load, which is equal to 46 A * 230 V = 10,380 W. The input power is equal to the power consumed by the motor at no-load, plus the core losses, which is equal to 1610 W + 2530 W = 4130 W.

Therefore, the efficiency is equal to 10,380 W / 4130 W = 2.51.

The distributions of solid wastes produced daily at a commercial facility are normally distributed with a mean of 10 yd3 and a standard deviation of 7 yd3. If you were to make a container size recommendation for this facility, what size would you propose? What important tradeoffs should be considered when selecting the size of the container?

It's quite perplexing to determine the perfect size of container for a facility whose waste quantity varies and is subject to changes frequently. A certain degree of burstiness is present in the distribution of solid waste generated on a daily basis in a commercial facility. However, using the available mean and standard deviation values, we can infer that a container size of 24 yd3 should be sufficient to hold the daily waste generated, considering that it's two standard deviations above the mean.

When selecting a container size, various tradeoffs must be considered. A large container is more efficient, as it would not require to be emptied as frequently, but it might be expensive and may take up more space. A smaller container may be less expensive and take up less space, but it would need to be emptied more frequently, which can result in higher transportation costs and more time spent on waste management. It is therefore essential to strike a balance between the frequency of emptying and the container size to ensure that the waste is managed effectively and efficiently.

In the above-given scenario, Technician A is correct because  low-drag calipers retract the pistons and pads farther from the rotor than traditional calipers.

Technician A is correct because low-drag calipers have a design that allows the brake pads to retract further away from the rotor when the brake pedal is released.

This reduces the amount of friction between the pads and the rotor, which in turn reduces the amount of heat generated and the wear on the brake pads and rotors. As a result, low-drag calipers improve the performance and longevity of the braking system.
