Answer:
cout<<"''<<user_word<<"' "<<user_number;
Explanation:
The above question was answered using C++ programming language.
The keyword cout represents print and it carries out print operation only.
It prints all variable in front of it.
Assume the values of user_word and user_number to be Charles and 20, respectively.
The output of the above instruction would be
'Charles' 20 just as it is in the sample output in the question.
In java programming language, it is
System.out.print("'"+user_word+"' "+user_number);
In Qbasic, it is
PRINT "'"+user_word+"' "+ user_number
Answer: Combustion of Hydrocarbons
Explanation:
The Independent variable in an experiment is the one whose effect on the dependent variable is being measured. The independent variable therefore is controlled to see the effect it will have in the experiment.
In this experiment, the scientists combusted different types of hydrocarbons (diesel, gasoline, natural gas and a gasoline/ethanol mixture) as they aimed to find out the effect that this burning would have on the environment thereby making the combustion of hydrocarbons the independent variable.
Answer:
Ceramic coating offers good protection to the car's surface. The nano-coating can protect the car from most scratches, dirt and chemical contaminants. Ceramic coating also doesn't have any side-effects to the original paint. Ceramic coating also lasts longer than regular paint.

Answer:
A) attached below
B) 743 KJ
C) 1.8983 KJ/K
Explanation:
A) Diagram of system schematic and set up states

<u>B) Calculate the amount of work received from the paddle wheel </u>
assuming ideal gas situation
v1 = v2 ( for a constant volume process )
work generated by paddle wheel = system internal energy
dw = mCv dT . where ; Cv = 0.743 KJ/kgk
= 5 * 0.743 * ( 500 - 300 )
= 3.715 * 200 = 743 KJ
<u>C) calculate the amount of entropy generated ( KJ/K )</u>
S2 - S1 = 1.8983 KJ/K
attached below is the detailed solution
