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.
Solution:
In the game Singularity, broken objects can be restored to their original condition by reversing time. This is an example of which time element of player adjustment.
Thus the required answer is player adjusted.
Answer:
2. Scientists use seismometers to measure the earthquake activity that occurs beneath a volcano. They then predict the eruption of that volcano.
Explanation:
The options are:
1. Before a volcano erupts, earthquake activity beneath the volcano decreases.2. Scientists use seismometers to measure the earthquake activity that occurs beneath a volcano. They then predict the eruption of that volcano.3. When a volcano erupts, the amount of carbon dioxide and sulfur dioxide emitted decreases. 4.Scientists measure the amount of these gases to determine the amount of magma present in the volcanic reservoir.
The answer is certainly 2. as seismometers are being used to find out the details of the earthquake activities which occur inside a volcano. And with this information, the volcanologists then predict the eruption of that particular volcano. Hence, the 2nd option does not have any factual errors, and all the others have factual errors.
I don't believe that there are rules.
Hope I helped,
