I'm confused as to if subclasses can call the supers without any implementation and what the right answer is
Answers
Answer:
E
Explanation:
Since Example1 and Example2 inherit from Example0, all classes have the method doNothing() at their disposal, so you can call it from e0, e1 and e2.
However, the arguments of this method are Example1 and Example2, so you cannot pass Example0 as a first argument, and you cannot pass Example0 or 1 as a second argument. That only leaves answer E.
You can call the inheritance relation an "is a kind of" relation. So Example1 is a kind of Example0, and Example2 is a kind of Example1, but also Example2 is a kind of Example0.
Now you can understand why e2 can be passed as an argument for Example1, because e2 is a kind of Example1.

sum =sum + i;
}
printf("The sum is = %d",sum);

Answers
A program that prints the sum on the first 10 natural numbers is:
int sum=0;int i=1;for(i=1; i <= 10 ; i++) // the value of i will be from 1 to 10{sum=sum+i; //each number will get added to the variable ‘sum’}System.out.println(sum); //What is a program?A computer program in a programming language is a set of instructions and commands written in a language that a computer can execute or understand.
Using the For Loop program, the variables of the first 10 natural numbers can be written as:
int sum=0;int i=1;for(i=1; i <= 10 ; i++) // the value of i will be from 1 to 10{sum=sum+i; //each number will get added to the variable ‘sum’}System.out.println(sum); //Learn more about writing a program here:

Digital cameras often have trouble with auto white balance, which can result in unattractive blue, orange, or green casts.
A: true
B: false
Answers
The statement about digital cameras often having trouble with auto white balance which can result in unattractive blue, orange or green casts is; A: True.
Let us first define white balance(WB).
White balance is defined as the process of removing unrealistic color casts, in a way that will make the objects that appear to be white in person to also be appear white in the photo.
Now, for a camera to have the right white balance, it will have to consider the "color temperature" of a light source i.e the relative warmth of white light.
Finally humans eyes are very good at judging which is white under different light intensities or sources, but that is not the case with digital cameras because they struggle with auto white balance and that could lead to different colors like unattractive blue, orange, or even green color casts.

Which CPU characteristic when enabled, doubles the number
of instructions which can be processed at once?
Answers
Answer:
A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions. The term has been used in the computer industry at least since the early 1960s. Traditionally, the term “CPU” refers to a processor, more specifically to its processing unit and control unit (CU), distinguishing these core elements of a computer from external components such as main memory and I/O circuitry.
The form, design and implementation of CPUs have changed over the course of their history, but their fundamental operation remains almost unchanged. Principal components of a CPU include the arithmetic logic unit (ALU) that performs arithmetic and logic operations, processor registers that supply operands to the ALU and store the results of ALU operations, and a control unit that fetches instructions from memory and “executes” them by directing the coordinated operations of the ALU, registers and other components.
Most modern CPUs are microprocessors, meaning they are contained on a single integrated circuit (IC) chip. An IC that contains a CPU may also contain memory, peripheral interfaces, and other components of a computer; such integrated devices are variously calledmicrocontrollers or systems on a chip (SoC). Some computers employ a multi-core processor, which is a single chip containing two or more CPUs called “cores”; in that context, single chips are sometimes referred to as “sockets”. Array processors or vector processors have multiple processors that operate in parallel, with no unit considered central.
