Consider the following information: Sales = $100,000 Total costs = $80,000 Tax rate = 20% Depreciation = $10,000 The depreciation tax shield (DT) is $[ans1] and the OCF (operating cash flow) is $[ans2]. Input an integer in each box with no comma. [Hint: OCF  = (Sales – Costs)x(1 – T) + Depreciation x T]

If the absolute temperature of a sample of Helium gas is increased by a factor of four, by what factor does the root-mean-square (vrms​) speed of the atoms change?

During an isothermal expansion, an ideal gas performs 500 J of work on its surroundings. What is the net heat Q absorbed by the system during this process?

# Q1.Write a Python snippet that prompts the user to enter a greeting. # If the user enters “Hello”, output “Hi there!”. # if the user enters “Goodbye”, output “See you later!”. # For any other input, output “I don’t understand.”. # Q2. Write a Python program that interacts with the user as follows: # a. Prompt the user to enter a meal choice. The valid options are: # Breakfast, Lunch, or Dinner. # If the user enters anything else, output: # Invalid entry. # and end the program. # b. If the meal choice is valid, prompt the user to enter a drink choice. # The valid drink options are: # Coffee, Juice, or Water. # If the drink entered is not one of these options, output: # Invalid drink choice. # and end the program. # c. Only the following specific meal and drink combinations should produce output: # – Breakfast with Coffee # – Lunch with Juice # – Dinner with Water # For these combinations, output exactly one of the following messages: # Breakfast with Coffee is a great start! # Lunch with Juice is refreshing! # Dinner with Water is a healthy choice! # d. If both the meal and drink are valid but do not form one of the listed # combinations, produce no output. # Sample Runs: # Valid Input: # Enter a meal: Lunch # Enter a drink: Juice # Lunch with Juice is refreshing! # Invalid Meal: # Enter a meal: Snack # Invalid entry. # Valid Meal but Invalid Drink: # Enter a meal: Dinner # Enter a drink: Soda # Invalid drink choice. # Q3. Understanding Boolean Logic (Program Comprehension) # This is a program comprehension question. # You do NOT need to write or submit any Python code. # Consider the following Python code: # condition = (50 < 40) or (75 == 75) and (200 > 300) # if condition == True: # print(“Success!”) # else: # print(“Failure!”) # Question: # What is the exact output produced when this code is executed? # Your answer should be ONE line of text exactly as it would appear # when the program runs. # Do NOT rewrite the code. # Do NOT explain your reasoning. # Only write the output.
