Answer:
The answer to this question is given below in the explanation section.
Explanation:
This question is about what is a good analogy for explaining the actions of a compiler? The correct option is <u> automatic programming of kitchen devices
.</u>
<u>
</u>
a hybrid ability of a car to use multiple energy sources (false)
this analogy is not correctly mapped on the compiler, becuase the compiler can be designed only for one type of language, for example, the program that calculates the average of students number can be easily programmed in C++ and in C#. But you cannot compile the C# program in C++ compiler and vice versa.
a street map of a local subdivision (false)
Because you can design a compiler for a not specific subdivision of programming.
an interpreter who speaks several languages
it is not an analogy, however, an interpreter can handle only one type of language.
an automatic programming of kitchen devices (true)
This is a good analogy of compiler because you give input to the device and that device based on your input gives you back an output. Similarly, you give input to the compiler in form of language syntax, and it automatically give you output based on your input.
B) a desktop is less likely to be stolen or damaged
Answer:
B. Access point repeater
Explanation:
RFID can be used for all of the listed applications except for Access point repeater. This is because Radio Frequency Identification is a technology, which includes wireless data capture and transaction processing for both short and long-range applications. Usually tracking, tracing, accessing, and managing information. It can unfortunately not be used for repeating the same RFID signal or any access point for that matter.
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
