No, it isn't. It can only perform basic mathematical calculations. A computer must be programmable in order to be Turing-complete.

In 1642, Blaise Pascal invented the Pascal's calculator, a mechanical calculator. The laborious arithmetic calculations required by his father's work as the supervisor of taxes in Rouen inspired Pascal to create a calculator.

It must have some kind of programming language in which you can write instructions that can be followed automatically or by a human operator to perform any type of data processing.

Thus, it can be concluded that Pascaline calculator is not actually a computer according to the Turing model.

The capacitive reactance of a DC series circuit increases when its capacitance decreases and vice-versa.

A DC series circuit can be defined as a type of circuit in which all of its resistive components are connected end to end, so as to form a single path for the flow of current.

This ultimately implies that, the same amount of current flows through a direct current (DC) series circuit.

Mathematically, the capacitive reactance of a DC series circuit is given by this formula:

\(X_C = \frac{1}{2\pi fC}\)

Where:

From the above formula, we can deduce that the capacitive reactance of a DC series circuit is inversely proportional to both frequency and capacitance. Thus, the capacitive reactance of a DC series circuit increases when its capacitance decreases and vice-versa.

In conclusion, a capacitor would influence a simple DC series circuit by blocking the flow of direct current (DC) through it.

The maximum allowable sustained pumping rate for the well in Eudora can be determined by considering the drawdown observed in a non-pumping well located 200 m away from the pumping well.

Drawdown is the decline in the water level caused by pumping from the well, and it is an indicator of the well's ability to sustain pumping at a given rate over a long period of time. The drawdown observed in the non-pumping well after 300 days of pumping is 1 m, which indicates that the pumping rate of 0.016 m3/s has caused a decline in the water level of 1 m. To determine the maximum allowable sustained pumping rate, we need to consider the hydraulic conductivity of the medium sand aquifer and the radius of influence of the pumping well.

The hydraulic conductivity of a medium sand aquifer is typically in the range of 10^-2 to 10^-3 m/s. Using this value and the drawdown observed in the non-pumping well, we can calculate the maximum pumping rate using the Theis equation, which relates the pumping rate, drawdown, and hydraulic conductivity to the well's radius of influence.

The radius of influence can be estimated as r = (KtS/4πT)^0.5, where K is the hydraulic conductivity, t is the time elapsed since pumping started, S is the drawdown, and T is the transmissivity of the aquifer. The transmissivity can be estimated as T = Kb, where b is the thickness of the aquifer.

Using the values from the problem, the maximum allowable sustained pumping rate can be estimated. The result can be compared to the desired pumping rate of 0.025 m3/s. If the maximum pumping rate is less than the desired pumping rate, the pumping rate will have to be reduced to ensure that the well can sustain pumping over a long period of time.

In conclusion, the maximum allowable sustained pumping rate for the well in Eudora can be estimated by considering the hydraulic conductivity of the medium sand aquifer, the drawdown observed in a non-pumping well, and the radius of influence of the pumping well. The result can be compared to the desired pumping rate to ensure that the well can sustain pumping at the desired rate over a long period of time.

Grounded windings electric motor problems can cause the motor housing to become energized. The correct option is C.

An electric motor with grounded windings may energise the motor casing. An unexpected electrical connection exists between a motor's windings and the motor housing when the windings are grounded.

Failure of the insulation or a wiring issue in the motor may be the cause of this. The motor housing, which is generally wired to the ground, gets electrically energised when the windings are grounded.

Due to the risk of electric shock if someone comes into contact with the powered motor casing, this poses a serious safety risk.

Therefore, in order to avoid such risky circumstances, it is essential to quickly identify and correct grounded windings.

Thus, the correct option is C.

Answer:

a) 47500 mg/L

b) 5250366.444  kg/year

Explanation:

Given data:

suspended solids removal efficiency = 20%

Flowrate in the primary clarifier ( Q ) = 20 MGD ( change to Liters/day

Q = 20* 10^6 * 3.785412  Liters /day

settled concentration  ( St ) = 950mg/L * 0.2 = 190 mg/L

amount of settled solid = Q * St

                                   = ( 20* 10^6 * 3.785412 ) * 190  = 14384.5656 kg/day

∴ Amount going into sludge with a flowrate of 0.08 MGD = 14384.5656 kg/day

a) concentration of solid in sludge  ( leaving the clarifier )

= amount of settled solid / flow rate out of the clarifier in liters/day

= 14384.5656 / ( 0.08 * 10^6 * 3.785412 )

= 0.0475 kg/L

= 47500 mg/L

b) Determine mass of solids that is removed annually

= 14384.5656 kg/day * 365 days

= 5250366.444  kg/year

Explanation:

Base current increases and collector current decreases

The collector current does reduces because electrons that moves from emitter to base and the electrons that moves from collector to base are both cancelled out. Some of these electrons enter from the emitter to the collector because, in a way, the emitter has been heavily döped

An increase in base current also means that there is more bias to the transistor

Explanation:

The distance below the top of the cliff that the two balls cross paths is 7.53 meters.

Given the following data:

Scientific data:

To determine how far (distance) below the top of the cliff that the two balls cross paths, we would apply the third equation of motion.

Mathematically, the third equation of motion is given by this formula:

\(V^2 = U^2 +2aS\)

Where:

Substituting the parameters into the formula, we have;

\(V^2 = 0^2 +2(9.8) \times 30\\\\V^2 = 588\\\\V=\sqrt{588}\)

V = 24.25 m/s.

Note: The final velocity of the first ball becomes the initial velocity of the second ball.

The time at which the two balls meet is calculated as:

\(Time = \frac{S}{U} \\\\Time = \frac{30}{24.25}\)

Time = 1.24 seconds.

The position of the ball when it is dropped from the cliff is calculated as:

\(y_1 = h-\frac{1}{2} at^2\\\\y_1 = 30-\frac{1}{2} \times 9.8 \times 1.24^2\\\\y_1 = 30-7.53\\\\y_1=22.47\;meters\)

Lastly, the distance below the top of the cliff is calculated as:

\(Distance = 30-22.47\)

Distance = 7.53 meters.

Answer:

Explanation:

To determine the drain current (ID) for each of the given values of VGS and VDS, we can use the following equation:

ID = kn/2 * (VGS - VT)^2 * (1 + λVDS)

where kn is the process transconductance parameter, VT is the threshold voltage, λ is the channel-length modulation parameter, and VDS is the drain-source voltage. In this case, kn = 0.18 mA/V^2, WL = 8, and VT = 0.4 V.

(a) For VGS = 0.8 V and VDS = 0.2 V:

ID = kn/2 * (VGS - VT)^2 * (1 + λVDS)

= 0.18 mA/V^2 / 2 * (0.8 V - 0.4 V)^2 * (1 + 0.01 V^-1 * 0.2 V)

= 0.036 mA

Therefore, the drain current is 0.036 mA for VGS = 0.8 V and VDS = 0.2 V.

(b) For VGS = 0.8 V and VDS = 1.2 V:

ID = kn/2 * (VGS - VT)^2 * (1 + λVDS)

= 0.18 mA/V^2 / 2 * (0.8 V - 0.4 V)^2 * (1 + 0.01 V^-1 * 1.2 V)

= 0.0846 mA

Therefore, the drain current is 0.0846 mA for VGS = 0.8 V and VDS = 1.2 V.

(c) For VGS = 0.8 V and VDS = 2.5 V:

ID = kn/2 * (VGS - VT)^2 * (1 + λVDS)

= 0.18 mA/V^2 / 2 * (0.8 V - 0.4 V)^2 * (1 + 0.01 V^-1 * 2.5 V)

= 0.1733 mA

Therefore, the drain current is 0.1733 mA for VGS = 0.8 V and VDS = 2.5 V.

(d) For VGS = 1.2 V and VDS = 2.5 V:

ID = kn/2 * (VGS - VT)^2 * (1 + λVDS)

= 0.18 mA/V^2 / 2 * (1.2 V - 0.4 V)^2 * (1 + 0.01 V^-1 * 2.5 V)

= 1.1916 mA

Therefore, the drain current is 1.1916 mA for VGS = 1.2 V and VDS = 2.5 V.

To divide the list into almost two equally-length parts and output two lists, the following Python program can be used:

my_list =

["1","2","5","8","9","0"]

list_length = len(my_list)if list_length % 2 == 0:  

# length is even   mid = list_length // 2   list1 = my_list[:mid]

 list2 = my_list[mid:]else:

 # length is odd   mid = list_length // 2   list1 = my_list[:mid+1]   list2 = my_list[mid+1:]print(list1) print(list2)

The above program divides the list into two almost equal parts by checking whether the length of the list is odd or even.

If the length of the list is even, it divides the list into two equal parts.

If the length of the list is odd, it divides the list into two parts where the first part has one more element than the second part.
