Answer: D. Searches for a file only in the directories that are in the path variable
Answer:
- You need to create a variable outside (before) the input loop.
- You need a variable inside your loop that temporarily holds the user input.
- In your loop, you will compare if the variable outside the loop is greater than (or less than) the new user input.
I don't know what program language you are using, but I will use python since it's easy to read and you will get the idea if you're using a different programming language.
<u>Code (Python)</u>
largestnum = 0
for x in range(6): <em>#loops 6 times</em>
newnum = int(input("Enter a number: ")) #ask user for input & converts to int.
if newnum > largestnum: <em>#if new number is greater than largest num </em>
largestnum = newnum <em>#make it the largest number</em>
<em> </em>print("Largest:", largestnum)
The reason why you need a variable outside of the loop is because after the loop is done all variables inside the loop are trashed and can no longer be accessed outside of the loop.

The value of total resistance of resistors connected in parallel is calculated through the equation,
R = 1 / (1/R1 + 1/R2 + 1/R3 + 1/Rn)
Substituting the known values,
R = 1 / (1/2 + 1/6 + 1/10)
R = 30/23 ohms
The formula for power with the use of resistance and voltage is,
P = V² / R
Substituting,
P = (100 V)² / (30/23 ohms)
P = 7.67 kW
Thus, the answer to this item is letter C.
