Answer:
All functions were written in python
addUpSquaresAndCubes Function
def addUpSquaresAndCubes(N):
squares = 0
cubes = 0
for i in range(1, N+1):
squares = squares + i**2
cubes = cubes + i**3
return(squares, cubes)
sumOfSquares Function
def sumOfSquares(N):
squares = 0
for i in range(1, N+1):
squares = squares + i**2
return squares
sumOfCubes Function
def sumOfCubes(N):
cubes = 0
for i in range(1, N+1):
cubes = cubes + i**3
return cubes
Explanation:
Explaining the addUpSquaresAndCubes Function
This line defines the function
def addUpSquaresAndCubes(N):
The next two lines initializes squares and cubes to 0
squares = 0
cubes = 0
The following iteration adds up the squares and cubes from 1 to user input
for i in range(1, N+1):
squares = squares + i**2
cubes = cubes + i**3
This line returns the calculated squares and cubes
return(squares, cubes)
<em>The functions sumOfSquares and sumOfCubes are extract of the addUpSquaresAndCubes.</em>
<em>Hence, the same explanation (above) applies to both functions</em>
Answer:
The answer is "Option A".
Explanation:
The elliptical curve cryptography system needs much shorter keys for cryptography, and it is very powerful because of the RSA cryptography method. It is also known as a key of 1024-bit, which is in comparison is equal to the 160-bit ECC key for cryptographic, that's why other options are not correct, which is defined as follows:
- In option B, It is higher the ECC key system, that's why it's wrong.
- In option C, It is a part of the RSA system but its value doesn't match the ECC system, that's why it is wrong.
- In option D, It's valued is just double to the RSA system, that's why it is wrong.

1. 3 times the light voltage, ie., 3*0.5 = 1.5V
2. Total R = 3*25 = 75Ω, V=1.5V, I = V/R = 1.5/75 = 20 mA
3. A 1.5V battery (e.g., an AA battery) with a charge of at least 20mAh. AA batteries should be able to handle this easily.
