Answer: TRUE
Explanation: Composite is simply used to refer to the existence of more than one event or pattern. The composite primary key as related to database management query refers to the synergy or combination of more than one field or column of a specified table which is used in sorting or accurate identification of a record. When attributes are combined, that is more than one, it assists in narrowing down the returned records such that records which are close and exclusive to the options specified are returned. Usually, the more the number of columns which makes uo the case mpoaite keys, the more unique and well sorted our returned output is.
Answer:
Answered below
Explanation:
# Program is written in Python programming language
conditioner_in_ml = 0
width = float(input("Enter width in inches: "))
height = float(input("Enter height in inches: "))
length = float (input("Enter length in inches: "))
#Calculate the volume
volume = width * length * height
#Calculate the amount of conditioner per 100 #cubic inches of volume
conditioner_in_ml = volume/ 100
print("The amount of conditioner required for $volume cubic inches is $conditioner_in_ml ml")
Answer:
(c) the dynamic type of reference will determine which of the methods to call.
Explanation:
Polymorphism in Object Oriented Programming typically means the same method name can cause different actions depending on which object it is invoked on. Polymorphism allows for dynamic binding in that method invocation is not bound to the method definition until the program executes.
So in the case of Animal superclass and Mammal subclass, both having a method called eat() with identical signatures and return types, depending on which reference, the correct method eat() will be called dynamically upon execution.
For example, if we have the following;
================================
<em>Mammal mammal = new Animal();</em>
<em>mammal.eat()</em>
================================
The eat() method that will be called is the one in the Mammal subclass.
However, if we have;
================================
<em>Animal animal = new Animal();</em>
<em>animal.eat()</em>
================================
The eat() method of the Animal superclass will be called.
Answer:
64
Explanation:
We have given the 32 bit architecture
We know that 1 byte =8 bit
So memory of given architecture 32 bit 
Total memory = 256 bytes
So total number of instruction that fit into 256 bytes 
So total 64 instruction can be fit in 256 byte memory.
