FOREACH, EXPLODE and MAIL are examples of crazy functions.

Answer:

Multimedia has become an essential and vital part of various sectors such as healthcare, education, entertainment, and marketing.

Explanation:

In the past, children primarily learned using textbooks, but now they engage with smart boards and other interactive digital devices that provide animated content.

The role of multimedia is crucial in entertainment, where there has been a significant increase in attendance for multimedia events.

Similarly, in the medical field, students can learn more effectively with the use of multimedia tools. Looking ahead, multimedia is expected to draw interest across all disciplines and its future seems promising.

Answer:

C3H8

Explanation:

Step 1:

Relevant details from the question are noted below:

Mass of the alkane is 1.17g

Volume (V) = 674 mL

Temperature (T) = 28°C

Pressure (P) = 741 mmHg.

Gas constant (R) = 0.08206 atm.L/Kmol

Step 2:

Convert to the appropriate units.

For Volume:

1000mL = 1L

So, 674mL = 674/1000 = 0.674L

For Temperature:

Temperature in Kelvin = Temperature in Celsius + 273

Temperature in Celsius = 28°C

Temperature in Kelvin = 28°C + 273 = 301K

For Pressure:

760mmHg = 1atm

So, 741 mmHg = 741/760 = 0.975atm

Step 3:

Calculate the moles of the alkane.

The moles of the alkane can be found using the ideal gas equation, presented below:

Volume (V) = 0.674L

Temperature (T) = 301K

Pressure (P) = 0.975atm

Gas constant (R) = 0.08206 atm.L/Kmol

Number of moles (n) =?

PV = nRT

n = PV /RT

n = (0.975 x 0.674)/(0.08206x301)

n = 0.0266 moles

Step 4:

Calculate the alkane’s molar mass.

Mass of alkane = 1.17g

Number of moles = 0.0266moles

Molar Mass =?

Number of moles = Mass/Molar Mass

Molar Mass = Mass/Number of moles

Molar Mass of alkane = 1.17/0.0266 = 44g/mol

Step 5:

Determine the molecular formula of the alkane.

This is based on:

The general formula for alkanes is CnH2n+2

To find the molecular formula, we start with n = 1, 2, 3, etc., until we find the molar mass of 44.

When n = 1

CnH2n+2 = CH4 = 12 + (4x1) = 16g/mol

When n = 2

CnH2n+2 = C2H6 = (12x2) + (6x1) = 30g/mol

When n = 3

CnH2n+2 = C3H8 = (12x3) + (8x1) = 44g/mol

It can be observed that for n equal to 3, the molar mass is 44g/mol.

Thus, the molecular formula of the alkane is C3H8.

Answer:

The type of session hijacking attack that Sean is illustrating is Blind Hijacking, option C.

Explanation:

This is because he is inserting harmful data or commands into the compromised communications within the TCP session, regardless of the source-routing being turned off. He is capable of sending the data or commands, but does not have the ability to view the responses.

Answer:

C. you possess insurance documentation

Explanation:

Being a resident does not automatically grant permission to operate a vehicle. For instance, a person might have residency but might also have a suspended license, which means they are unable to drive.

Typically, insurance applies to the CAR rather than the individual. Therefore, the general guideline is:

A different person is permitted to drive your vehicle if you possess proof of insurance.

Answer:

Explanation:

When removing items from a dictionary, always specify the key in quotation marks.

For example: del country_capital['Prussia']

Failing to place it in quotes will cause the interpreter to view Prussia as a variable, resulting in an error saying that Prussia is not defined.

Code:

user_input=input("") #taking input from user

entries=user_input.split(',')    

country_capital=dict(pair.split(':') for pair in entries) #creating the dictionary from user input

del country_capital['Prussia'] #removing Prussia; failure to include quotes results in an error

print('Prussia deleted?', end=' ')

if 'Prussia' in country_capital: #verifying the presence of Prussia in the dictionary

print('No.')

else:

print('Yes.')

print ('Spain deleted?', end=' ')    

if 'Spain' in country_capital: #checking if Spain is present in the dictionary

print('No.')

else:

print('Yes.')

print ('Togo deleted?', end=' ') #verifying the existence of Togo in country_capital

if 'Togo' in country_capital:

print('No.')

else:

print('Yes.')
