Parallel arrays are those arrays which are used to store some records which needs more than one array to hold a entry but are interrelated and should be accessed by same index number. As they are of different data types so can't be stored as multi-dimensional array or matrix. Then parallel array comes to rescue. For example : Details of a student.
Name, age and ID of a student needs to be stored. So, three arrays can be made and each entry should be accessed by same index number.
Answer:
Python code given below
Explanation:
def calculate_storage(filesize):
block_size = 4096
full_blocks = filesize // block_size
partial_block = filesize % block_size
if partial_block > 0:
return (full_blocks + 1) * block_size
return filesize
print(calculate_storage(1))
print(calculate_storage(4096))
print(calculate_storage(4097))

Answer:
56 J
Explanation:
Formula to find the kinetic energy is :
E_kEk = \frac{1}{2}21 × m × v²
Here ,
m ⇒ mass
v ⇒ velocity
Let us solve now
E_kEk = \frac{1}{2}21 × m × v²
= \frac{1}{2}21 × 7 kg × ( 4 ms⁻¹ )²
= \frac{1}{2}21 × 7 × 16
= \frac{1}{2}21 × 112
= 56 J
