Answer:
Centrifugation.
Explanation:
When the liquid is spun rapidly, the denser particles are forced to the bottom and the lighter particles stay at the top. This principle is used in centrifugation.
Centrifugation can be defined as the process of separating particles from a liquid solution according to density, shape, size, viscosity through the use of a centrifugal force. In order to separate these particles, the particles are poured into a liquid and placed in a centrifuge tube. A centrifuge is an electronic device used for the separation of particles in liquid through the application of centrifugal force. Once the centrifuge tube is mounted on the rotor of the centrifuge, it is spun rapidly at a specific speed thereby separating the solution; denser particles are forced to the bottom (by moving outward in the radial direction) and the lighter particles stay at the top as a result of their low density.
Answer:
The following are the code to this question:
code:
System.out.println(x); //use print method to print value.
Explanation:
In the given question, it simplifies or deletes code in the 11th line. This line has a large major statement.
In the case, the tests fail because only 1 line of output is required by the tester, but two lines are obtained instead.
It's to demonstrate that the input/output or testing requirements function throughout the model.
Answer:
Calculate the average processing time of the new software
Explanation:
Since the average processing time of the old software is already known, the simplest test to see if the new software is faster than the old software will be to calculate the average processing time for the new software and compare it with the average processing time of the old software.
If the new software have an average processing time lower/smaller than that of the old software; we conclude that the new software is faster.
If the new software have an average processing time higher/larger than that of the old software; we conclude that the old software is faster.
Answer:
Replace
if userAge > 20
with
userAge > 19
Explanation:
if userAge > 20 checks if age is 21, 22, 23, 24........
The else condition which prints "I am a teenager" checks if age is 20, 19, 18....
Notice that 20 is inclusive of the else condition; this shouldn't be because for userAge to be less than 20, 20 isn't inclusive
To solve this,
Replace if userAge > 20 with userAge > 19
So that, the else
The else condition which prints "I am a teenager" checks if age is 19, 18, 17, 16....
