Think about a wholesaler and manufacturer of jams and jellies. To prepare for supply delays, they store extra supplies of raw materials like fruit and sugar on hand.

This serves as their backup supply. In the standard formula, buffer stock is determined as the product of the maximum daily usage (the maximum number of units sold in one day) and the maximum lead time (the length of time it has taken your supplier to ship the stock) minus the product of the average daily usage (the average number of units sold in 1 day). A surplus of raw materials is maintained on hand as a buffer stock to protect against any unanticipated inventory shortages prior to production.

Answer: P = 7.5 × 10^-17

Explanation:

Given that the retraction speed = 1000nm/s

The mechanical power P exerted on the protein will be the product of exerted force F and the speed V. That is,

P = FV

Let consider the attached graph to solve the question.

The mechanical power P will be the area under the graph.

At V = 1000nm/s , F = 75 pN

Using the formula below

P = V × F

Substitute V and F into the formula

P = 1000 × 10^-9 × 75 × 10^-12

P = 7.5 × 10^-17 W

Therefore, the mechanical power exerted on the protein when the retraction speed is 1000 nm/s is 7.5 × 10^-17 watt.

Answer:

  4 A

Explanation:

Current is found using Ohm's law.

  I = V/R

  I = (240 volts)/(60 ohms) = 4 A

The heating element current is 4 amperes.

The accelerations of points C and D are -1.3 m/s²  and 3.0 m/s² , respectively, and the load L has a tension of 19.62 N.

To calculate the accelerations of points C and D and the load L, we need to use the following equations:

Acceleration = Radius x Angular Acceleration
Load L = Tension in rope

First, let's calculate the radius of each drum. Assuming that the pulleys are the same size, we can use the radius of one of the drums:

Radius = Diameter / 2 = 1 meter / 2 = 0.5 meters

Next, let's calculate the angular acceleration of each drum:

Angular Acceleration of drum A = -2.6 rad/sec²  (negative because the angular velocity is decreasing)
Angular Acceleration of drum B = 6.0 rad/sec²  (positive because the angular velocity is increasing)

Using the equation for acceleration, we can calculate the accelerations of points C and D:

Acceleration of point C = Radius x Angular Acceleration of drum A = 0.5 meters x (-2.6 rad/sec² ) = -1.3 m/s² (negative because the acceleration is in the opposite direction to the motion)
Acceleration of point D = Radius x Angular Acceleration of drum B = 0.5 meters x 6.0 rad/sec²  = 3.0 m/s²  (positive because the acceleration is in the same direction as the motion)

Finally, we can calculate the tension in the rope, which is equal to the load L:

Tension in rope = Load L = 2 x (9.81 m/s² ) = 19.62 N (assuming a mass of 2 kg for the load)

Therefore, the accelerations of points C and D are -1.3 m/s² and 3.0 m/s² , respectively, and the load L has a tension of 19.62 N.

A Mealy machine and a Moore machine are both types of finite state machines, which are used to model and control systems with discrete states. However, they differ in how they output information.

In a Mealy machine, the outputs depend on both the current state and the input that is currently being processed. This means that the output can change at any point during the transition between states, and it can be influenced by the input. For example, a Mealy machine could be used to control a traffic light, where the output (the color of the light) depends on both the current state (green, yellow, or red) and the input (the presence of cars at the intersection). In contrast, a Moore machine outputs information based solely on the current state. This means that the output only changes when the machine transitions to a new state. For example, a Moore machine could be used to control a vending machine, where the output (the product dispensed) depends only on the current state (which product has been selected). Overall, the key difference between a Mealy machine and a Moore machine is how they handle output. Mealy machines use both current state and input to determine output, while Moore machines use only current state.

d.  the temperature (K) at state 3 is   \(\mathbf{ T_3 = 532.959 \ K}\)

Explanation:

From the given information:

T1 (K) = 249

P1 (kPa) = 61

V1 (m/s) = 209

rp = 10.7

rc = 1.8

The objective is  to determine the following:

a. Determine the temperature (K) at state 2.

b. Determine the pressure (kPa) at state 2.

c. Determine the specific enthalpy (kJ/kg) at state 2.

d. Determine the temperature (K) at state 3.

To start with the specific enthalpy (kJ/kg) at state 2.

By the relation of steady -flow energy balance equation for diffuser (isentropic)

\(h_1 + \dfrac{V_1^2}{2}=h_2+\dfrac{V^2_2}{2}\)

\(h_1 + \dfrac{V_1^2}{2}=h_2+0\)

\(h_2=h_1 + \dfrac{V_1^2}{2}\)

For ideal gas;enthalpy is only a function of temperature, hence \(c_p\)T = h

where;

\(h_1\) is the specific enthalpy at inlet  = \(c_pT_1\)

\(h_2\) is the specific enthalpy at  outlet = \(c_pT_2\)

\(c_p\)  = 1.004  kJ/kg.K or 1004 J/kg.K

Given that:

\(T_1\) (K) = 249

\(V_1\) (m/s) = 209

∴

\(h_2=C_pT_1+ \dfrac{V_1^2}{2}\)

\(h_2=1004 \times 249+ \dfrac{209^2}{2}\)

\(h_2 = 249996+21840.5\)

\(\mathbf{\mathtt{h_2 = 271836.5 \ J/kg}}\)

\(\mathbf{h_2 = 271.84 \ kJ/kg}}\)

Determine the temperature (K) at state 2.

SInce; \(\mathtt{h_2 = c_pT_2 = 271.84 \ kJ/kg}\)

\(\mathtt{ c_pT_2 = 271.84 \ kJ/kg}\)

\(\mathtt{T_2 = \dfrac{271.84 \ kJ/kg}{ c_p}}\)

\(\mathtt{T_2 = \dfrac{271.84 \ kJ/kg}{1.004 \ kJ/kg.K}}\)

\(\mathbf{T_2 =270.76 \ K}}\)

Determine the pressure (kPa) at state 2.

For isentropic condition,

\(\mathtt{ \dfrac{T_2}{T_1}= \begin {pmatrix} \dfrac{p_2}{p_1} \end {pmatrix} ^\dfrac{k-1}{k}}\)

where ;

k = specific heat ratio = 1.4

\(\mathtt{ \dfrac{270.76}{249}= \begin {pmatrix} \dfrac{p_2}{61} \end {pmatrix} ^\dfrac{1.4-1}{1.4}}\)

\(\mathtt{ 1.087389558= \begin {pmatrix} \dfrac{p_2}{61} \end {pmatrix} ^\dfrac{0.4}{1.4}}\)

\(\mathtt{ 1.087389558 \times 61 ^ {^ \dfrac{0.4}{1.4} }}=p_2} ^\dfrac{0.4}{1.4}}\)

\(\mathtt{ \mathbf{ p_2 = \sqrt[0.4]{3.519487255^{1.4}} }}\)

\(\mathtt{ \mathbf{ p_2 = 81.79 \ kPa }}\)

d. Determine the temperature (K) at state 3.

For the isentropic process

\(\mathtt{\dfrac{T_3}{T_2} = \begin {pmatrix} \dfrac{p_3}{p_2} \end {pmatrix}^{\dfrac{k-1}{k}}}\)

where;

\(\mathtt{\dfrac{p_3}{p_2} }\) is the compressor ratio \(\mathtt{r_p}\)

Given that ; the compressor ratio \(\mathtt{r_p}\) = 10.7

\(\mathtt{\dfrac{T_3}{T_2} = \begin {pmatrix} r_p \end {pmatrix}^{\dfrac{k-1}{k}}}\)

\(\mathtt{\dfrac{T_3}{270.76} = \begin {pmatrix} 10.7 \end {pmatrix}^{\dfrac{1.4-1}{1.4}}}\)

Answer:

Made of Silicon.

Explanation:

A diode is a semiconductor device use in mostly electronic appliances. It is two terminals device consisting of a P-N junction formed either in Germanium or silicon crystal.

Diode can be forward biased or reverse biased.

When a diode is forward biased and the applied voltage is increased from zero, hardly any current flows through the device in the beginning.

It is so because the external voltage is being opposed by the internal barrier voltage whose value is 0.7v for silicon and 0.3v for germanium.

If you measure 0.7 V across a diode, the diode is probably therefore made of Silicon.

Here is the fractional_part() function:

def fractional_part(numerator, denominator):

   if denominator != 0:

       return (numerator % denominator)/denominator

   else:

       return 0

Explanation:

I will explain the code line by line.

The first statement it the definition of function fractional_part() which takes two parameters i.e. numerator and denominator to return the fractional part of the division.

Next is an if statement which checks if the value of denominator is 0. If this is true then the function returns 0. If this condition evaluates to false which means that the value of denominator is not 0 then return (numerator % denominator)/denominator  is executed. Now lets see how this statement works with the help of an example.

Lets say the value of numerator is 5 and denominator is 4. (numerator % denominator)/denominator will first compute the modulus of these two values. 5 % 4 is 1 because when 5 is divided by 4 , then the remainder is 1. Now this result is divided by denominator to get the fractional part. When 1 is divided by 4 the answer is 0.25. So this is how we get the fractional part which is 0.25.

Well, the nice thing about pseudocode is that it doesn’t need to match anything that a compiler or interpreter would recognize as valid syntax. Thus, you can basically write it any way you want, as long as the intention is clear.

The idea of pseudocode is that you describe the program flow, without getting bogged down into the specifics of a particular language.That being said, some programming languages use the len function or method, which some might write as length … so you might write something like:

len(my_array) # using a function

length(my_array)

my_array.length # using a property or attribute

my_array.length() # using a method

The pressure regulator valve keeps the pressure at a regulated level by exhausting excess pressure back to the oil pump.

The pressure regulator valve, also known as the relief valve, is a key component of an engine's oiling system. The pressure regulator valve maintains a regulated pressure in the oil system by controlling the flow of oil and directing excess oil back to the oil pump when the pressure exceeds the set limit.The pressure regulator valve is usually found in the oil pump, which is located in the engine block's bottom end.

It's usually located close to the engine's oil filter. The oil pump sucks oil from the engine's oil pan and directs it through the engine's oil galleries and bearings. The pressure regulator valve is responsible for keeping the pressure within the specified range by controlling the flow of oil back to the oil pump. It opens when the oil pressure exceeds the limit, allowing excess oil to bypass the engine's bearings and returning it to the oil pump, preventing damage to the engine's oiling system.
