Answer:
def sum_1k(M):
s = 0
for k in range(1, M+1):
s = s + 1.0/k
return s
def test_sum_1k():
expected_value = 1.0+1.0/2+1.0/3
computed_value = sum_1k(3)
if expected_value == computed_value:
print("Test is successful")
else:
print("Test is NOT successful")
test_sum_1k()
Explanation:
It seems the hidden part is a summation (sigma) notation that goes from 1 to M with 1/k.
- Inside the <em>sum_1k(M)</em>, iterate from 1 to M and calculate-return the sum of the expression.
- Inside the <em>test_sum_1k(),</em> calculate the <em>expected_value,</em> refers to the value that is calculated by hand and <em>computed_value,</em> refers to the value that is the result of the <em>sum_1k(3). </em>Then, compare the values and print the appropriate message
- Call the <em>test_sum_1k()</em> to see the result
Answer:
File manager
Explanation:
From the list of options 1 to 4, only option (2) is correct
Explaining the options one after the other
- Web browser: It lets users access the internet

Answer:
Several of the subsystems evolved during the program through design changes: The parachute system, essential for booster recovery, was redesigned with larger parachutes in 1983. Frangible nuts, used in the space shuttle pad hold down and release system, were redesigned in 2008.

Answer:
Differ in the quality of their transmission.
Explanation:
For example, when using the public phone box, wired transmission is done not wireless as in cell phones. Public phone box use electronic signals transmitted through a cable network to send voice data which are not very effective for long distance communication.
However, cell phones wirelessly send electromagnetic wave signal to a cell tower close to the caller and then the information is then transmitted to cell tower close to the receiver within a split of a second. This method of communication has much advantages.
