Answer:
D. 4x as much
Explanation:
The answer is pretty simple. The question is asking about 10m/s and 20m/s right? Take a look at the energy at each point on the graph. At 10m/s the kinetic energy is 100 on the graph. At 20m/s the kinetic energy is 400. You'll notice that 100 x 4 is 400 - That's the answer.
You can also prove this mathematically. The formula for kinetic energy is

The question says: constant mass so we can ignore that for now.
(1/2) * 10^2 is (1/2) * 100 = 50
for the 20m/s ball it would be
(1/2) * 20^2 = 400 * 1/2 = 200
Once again, you see that it is 4x
Answer:
Multitasking is a process in which we do multiple task at a time.
In computing system, multitasking is the concept of performing different types of multiple task and process over a certain period of time by executing simultaneously.
Operating system basically allow various task to run simultaneously by the user. In an operating system, each task consume storage system and all the other resources.
Multitasking function facilitate memory isolation in the processor and also supported different levels of security system in the operating system. For example, "a programmer working on any program in a system and as well as listening the music then, it perform multiple task at the same time".
Answer:
Explanation:
The constant function is useful in algorithm analysis, because it characterizes the number of steps needed to do a basic operation on a computer, like adding two numbers, assigning a value to some variable, or comparing two numbers. Executing one instruction a fixed number of times also needs constant time only.
Using the knowledge in computational language in JAVA it is possible to write a code that use factor levels that can be used as valid R variable names
<h3>Writting the code in JAVA:</h3>
<em> method = "repeatedcv"</em>
<em> , number = 10</em>
<em> , repeats = 1 </em>
<em> , verboseIter = TRUE</em>
<em> , summaryFunction = fivestats</em>
<em> , classProbs = TRUE</em>
<em> , allowParallel = TRUE)</em>
<em />

Answer: A class that implement an interface must contain methods for all abstract methods in the interface. Otherwise, the class must be declared as abstract.
Explanation:
It is necessary to implement all the abstract method that are present in the interface. Basically, this is one of the rule of abstract method. As, abstract method is define as without any implementation.
If any class contain abstract method then, it must be declare as abstract. Therefore, if a class are not implemented an interface method then, it should be declare as abstract.
