Given a matrix input_matrix, return a Numpy array that consists of every entry of A that has: an even row index in the range [0, 7) an odd column index in the range [3, 8) This can be accomplished in a single line. def PROBLEM3 (input_matrix):
# YOUR CODE GOES HERE
return output_matrix
# DO NOT MODIFY
np. random. seed (3251)
example = np. random. randint(0, 10, (10,10))
print(example)
print(PROBLEM3 (example))

answer: when the substance contain the two parts (polar and non-polar) like soap.

explanation:

soap is produced from the basic hydrolysis of ester "saponification", it is considered as a salt of hydrocarbons. the soap molecule contains the two parts: a polar group   (-coo-na+) and a non-polar group (r-hydrocarbon part). the polar group is called the head and the tail is the non-polar group. the polar group is hydrophilic in nature (water loving) and the non-polar group is hydrophobic in nature (water repelling).the polar/non-polar nature of a substance is useful that it can dissolve the non-polar substances by the polar part and also can dissolve the polar substances by the non-polar part. it commonly used in detergents and soaps.
