Give an example of a control system with a single state variable. Then, add up to two more state variables, one at a time. Describe how the control system changes (additional sensors, feedback, etc.).

(a) The mass flow rate of air is 23.67 Kg/s

(b) The total rate of heat transfer is 21090 kw

(c) the percent thermal efficiency is 71.12 %

In thermodynamics, thermal efficiency (η[tex]_{th}[/tex]) is a dimensionless performance measure of a device that consumes thermal energy, like an internal combustion engine, steam turbine, steam engine, boiler, furnace, refrigerator, air conditioners, and so on.

Thermal efficiency is the ratio of net work output to heat input for a heat engine; thermal efficiency (also known as the coefficient of performance) for a heat pump is the ratio of net heat output (for heating) or net heat removed (for cooling) to energy input (external work).

A heat engine's efficiency is fractional because the output is always less than the input, whereas a heat pump's COP is greater than 1. The Carnot theorem further limits these values.

Method or operator can be used to concatenate lists--- B. +  operator is used to concatenate lists.

See below example

list1 = ["a", "b" , "c"]

list2 = [1, 2, 3]

list1 = list1+ list2

print(list1)

29:What will be the value of the variable list after the following code executes?

A. [1,2,3,10]

List index starts form 0. So the statement list[3]=10 will override the last element to 10.

30:Consider the following list: inventory = ["washer", "dryer", "microwave") Which of the following will display the item value, "dryer"?

B. print(inventory[1])

List index starts form 0. Below are indexes of list.

inventory[0]= "washer"

inventory[1]= "dryer"

inventory[2]="microwave"

Hence inventory[1] will print "dryer"

31:  What will be the value of the variable list2 after the following code executes?

B. [1,2,3]

Elaborating it further:

# Initialize list1 to [1,2,3]

list1=[1,2,3]

# Initialize list2 as empty list

list2=[]

# Add all element of list1 to list2 one by one. So now list2 will become [1,2,3]

for element in list1:

 list2.append(element)

# Change values of list1 to [4,5,6]. Remember this statement will not change values of list2. list2 will remain [1,2,3]

list1=[4,5,6}

32: Given that: aList = [1,2,3,4] which of the following will display the list [2,3,4] at the screen?

D. print(aList[-3:]

Here start index range is -3, that is 3rd element from end of list- that is 2.

And end index is not given in option D. That means all elements after the start index.

So we will get [2,3,4]

33:Given that: aList = [1,2,10,11,12,13] del aList[3] what will be printed by print (aList)

C. [1,2,10,12,13]

del aList[3] will delete element present at 3rd index. List index starts from 0. So this will delete 11 from list.

34:Given that: my_tools = ['hammer', 'screwdriver', 'wrench', 'pliers', 'nailer', 'table saw') my_tools[2:4]= ['chainsaw', 'chipper'] what will be printed by print

C. ['hammer', 'screwdriver', 'chainsaw', 'chipper', 'nailer', 'table saw']

my_tools[2:4]=["chainsaw","chipper"]

Index range [2:4] meanse index 2 and 3. That means element present at index 2 will be replaced by "chainsaw" .

And element present at index 3 will be replaced by "chipper"

35: Which of the following will change the list names to ['Dan', 'Mary', Juanita', 'Harry', 'Sarah')

D. Names.pop(-4)

Here we need to delete 'Bill' from the list.

Bill is present at index 2 in list. But there is no del or pop operation given for index 2.

Now if we take negative index from end of list, then 'Bill' is present at -4 index from end of list. So Names.pop(-4) will delete 'Bill'.

Simulink® models can handle signals in both discrete and continuous time. Models created with the DSP System ToolboxTM are only meant to process discrete-time signals. A discrete-time signal is a series of values that correspond to specific points in time.

The signal's sample times are the time instants at which the signal is defined, and the associated signal values are the signal's samples. A discrete-time signal has traditionally been considered undefined at points in time between the sample times.

The sample period Ts of a periodically sampled signal is the equal interval between any two consecutive sample times. The sample rate Fs is equal to the sample period's reciprocal, or 1/Ts. The number of samples in the signal per second is defined as the sample rate.

A utility company charges 8.2 cents/kWh. If a consumer operates a 60-W light bulb continuously for one day, he would charged 11.808 cents.

To calculate the amount of energy used, multiply the power by the length of time the bulb is on.

1.44 kWh is equal to W=pt=6024Wh=0.96kWh.

C = 8.2 cents multiplied by 0.96 to produce 11.808 cents.

There are 100 cents in a $1, hence a cent is one hundredth of a dollar. The cent, which equals one hundredth of the fundamental unit of currency, is also present in many other currencies, including those of the European Union, Estonia, and Hong Kong. Cent is derived from the Latin word centum, which means "hundred." Cent originally meant "one hundred" in Middle English, but by the 1600s it had changed to "one hundredth."

There are no tolerances associated with basic dimensions because, in theory, they are perfect dimensions. An acceptable degree of dimensional variation that nevertheless permits an object to operate properly is referred to as a tolerance. Limit dimensions, unilateral tolerances, and bilateral tolerances are the three fundamental tolerances that appear on working drawings the most frequently. Between the upper (maximum) and lower (lowest) bounds, tolerance is the overall range within which a dimension may change. Tolerances are used to control the parts on production drawings because it is impossible to manufacture everything to an exact size.

Always run before the subclass constructor is the superclass constructor.The final modifier must be overridden in a subclass when a method is declared with it. A superclass has access to packages.

A subclass must utilize the public accessor and mutator methods rather than the private instance variables of the superclass in order to access the public methods from the superclass that it extends. Additionally, constructors from the superclass are not inherited by subclasses. We utilize the super() function to directly invoke the superclass constructor from the subclass constructor. It's an exclusive variation of the super keyword. Only within the subclass constructor may super() be used, and it must come first. Only the subclass' instance variables can be initialized by the constructors. As a result, when a subclass object is created, the subclass object must also immediately call one of the superclass' constructors.

An electric circuit is a closed loop in which electric current flows.

What is circuit?
Electronic components such as resistors, circuitry, capacitors, inductors, and diodes are connected by conductive cables or traces that allow electric current to flow between them. It is a specific kind of electrical circuit, and in order for a circuit to be called electronic rather than electrical, there usually needs to be at least each active component present. Signals can be amplified, calculations can be made, and data can be transported from one location to another thanks to the combination of factors and wires.

Electric current is generated by a power source, such as a battery, and can travel through conductors such as wires, before returning to the power source. Electric circuits can be divided into two types: series and parallel circuits.

A series circuit is a circuit in which all components are connected in a single loop, so that the same current flows through each part of the circuit. This means that the current passing through each component is the same, and the voltage across each component is the same.

A parallel circuit is a circuit in which components are connected side by side, so that each component is connected to the power source independently. This means that the current passing through each component can be different, and the voltage across each component can be different.

You would also need to know the location of the center of mass of the bar, as well as any pivot points or points of support on which the bar is resting.
