Answer: Input Voltage
Explanation:
Based on the information given, since the power supply to install in the system is being determined, the input voltage is the most important characteristic to consider when choosing a power supply.
The input voltage indicates the type of voltage and the electrical current that's required to power a device safely and effectively.
Answer:
The solution code is written in Python:
- def nested_list_string(list2D):
- output = ""
- for i in range(0, len(list2D)):
- for j in range(0, len(list2D[i])):
- output += str(list2D[i][j]) + " "
-
- return output
Explanation:
Let's create a function and name it as nested_list_string() with one input parameter, list2D (Line 1).
Since our expected final output is a string of number and therefore we define a variable, <em>output</em>, to hold the string (Line 2).
Next use two for loops to traverse every number in the list and convert each of the number to string using <em>str()</em> method. Join each of individual string number to the output (Line 3-5).
At the end, we return the output (Line 7)
Answer:
A pointer is a variable that stores the address of another variable. Unlike other variables that hold values of a certain type, pointer holds the address of a variable. For example, an integer variable holds (or you can say stores) an integer value, however an integer pointer holds the address of a integer variable.
Answer:
The Compass
Explanation:
The compass was one of the foremost technological inventions that forever changed sea navigation.
Before its invention, sailors used landmarks to navigate and when it got dark, they had to stop and wait for daybreak before resuming their journey. Some other people used the inaccurate means of the sun and stars to navigate at sea.
But with the invention of the compass, all these problems were a thing of the past because the compass could provide direction despite the weather or time of the day and as a result, it opened more trade routes and assisted in the Age of Discovery.
