Answer:
the difference in pressure between the inside and outside of the droplets is 538 Pa
Explanation:
given data
temperature = 68 °F
average diameter = 200 µm
to find out
what is the difference in pressure between the inside and outside of the droplets
solution
we know here surface tension of carbon tetra chloride at 68 °F is get from table 1.6 physical properties of liquid that is
σ = 2.69 × 
N/m
so average radius = 
= 100 µm = 100 ×
m
now here we know relation between pressure difference and surface tension
so we can derive difference pressure as
2π×σ×r = Δp×π×r² .....................1
here r is radius and Δp pressure difference and σ surface tension
Δp = 
put here value
Δp = 
Δp = 538
so the difference in pressure between the inside and outside of the droplets is 538 Pa
Answer:
- def processString(sentence):
- middle = len(sentence) // 2
- output = sentence[0: middle - 5] + sentence[middle+5:]
- return output
-
- print(processString("I have a dream"))
Explanation:
Create a function processString that take sentence as input paratemer (Line 1).
Next create a variable middle to hold the value of middle index of sentence string (Line 2)
Build the output string by slicing the input sentence from first character to character middle - 5th and from middle + 5th till the end of the string (Line 3).
Test the function using a sample sentence and we shall get the output "I am"
Yes i is the time of the day you get to frost the moon and back and then you can come over and then go to hang out with me me and then go to hang out
Answer:
The long derivation for work of a mechanically reversible, isothermal compression was done with detailed steps as shown in the attachment.
Explanation:
what is applied here is a long derivation from Work done in an isobaric process, the expression for the compressibility factor (Z) and the equation of state that was given. The requisite knowledge of Differentiation and Integration was used.
The detailed derivation from firs principle is as shown in the attachment.
Answer:
1. Costs and frequency of change.
2. The most important ‘non-functional’ requirements. Different systems have different priorities for non-functional requirements.
3. The software lifetime and delivery schedule.
Explanation:
The process of requirement gathering is required in both generic and customized software.
• A document to define the development process is required in all type of software application.
• Updating is required in each type of software. For doing so, new version of each type of software is released.
• Maintenance is an important part of software development. It is required in each type of application development.
• Software has some minimum requirements to execute. So, platform dependability is considered in all software development.
