Answer:
Option (B) Overheated CPU
Explanation:
- The above problems mentioned are due to the problem with the CPU.
- Overheated CPU can result into freezing the computer and unexpected rebooting.
- CPU stands for Central Processing Unit and is responsible for all the instabilities in the hardware parts of the computer.
- So, option (b) is true.
- A Network Card is responsible for connecting the computer to the internet. It also has other names like Ethernet Card. A bad Network Card results in problems with the internet and network connections but not the above problems. So, option (A) is false.
- UPS is Uninterrupted Power Supply. It is an external power device to provide the power supply to the computers in case of emergencies to not shut down the computer instantaneously. The above problems are not likely to be the caused by the failed UPS. So, option (C) is false.
- Drive is a hardware device to store information. It can be removable drive (optical drives like CDs, DVDs ) or non removable like ( Hard Disk Drive ). A failed drive results in problems with the storing information. The above problems are not associated with it. So, option (D) is also false.
It could be a

Answer:
What Is Computer? Here's Why: The characteristics of computers that have made them so powerful and universally useful are speed, accuracy, diligence, versatility and storage capacity. Let us discuss them briefly. Computers work at an incredible speed. A powerful computer is capable of performing about 3-4 million simple instructions per second.
Explanation:
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.
