Answer:
The program written in Python is as follows:
<em>See Explanation section for line by line explanation</em>
for n in range(100,1000):
isum = 0
for d in range(1,n):
if n%d == 0:
isum += d
if isum == n * 2:
print(n)
Explanation:
The program only considers 3 digit numbers. hence the range of n is from 100 to 999
for n in range(100,1000):
This line initializes sum to 0
isum = 0
This line is an iteration that stands as the divisor
for d in range(1,n):
This line checks if a number, d can evenly divide n
if n%d == 0:
If yes, the sum is updated
isum += d
This line checks if the current number n is a double-perfect number
if isum == n * 2:
If yes, n is printed
print(n)
<em>When the program is run, the displayed output is 120 and 672</em>

Explanation:
When I think about computers, I can understand about the software and the hardware, we can touch the hardware, but the software don't because is only data stored in the hardware, we can interact with the stored data using the hardware, we can complete a system with data, software, hardware, and people, people try to learn about software because it is better paid than fix a hardware.
The density of mercury is 13.6 grams per cubic centimeter. Complete the steps for converting 13.6 g/cm3 to kg/m3.
(1 kg = 1,000 g, 1 m3 = 106 cm3)
13,600
106
1,360
1 g
1 kg
1 m3
