Consider the following code segment: class Fruit : _type = "Fruit" def __init__(self, color) : self._color = color What is the name of the class variable?

_type is the correct answer for the above question

Explanation:

The class variable is a variable that is defined in the class and the instance variable is defined in the constructor of the class using the self keyword.The class variable is used as the static variable, but the instance variable is called by the help of objects only.The above program holds only one class variable which is "_type" because it is defined in the class.

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.
