C. The net charge does not change. The charge remains neutral and thus,
polarization takes effect. Polarization simply means electrons and protons are separated into opposites. To best explain this, we can use a rubber balloon that has been rubbed against animal fur. Assume is has been negatively charged, bring it close to the object and make sure that these two do not touch. Electrons within the object will experience a repulsive force.
</span>
Since repulsion will be greatest for those
electrons nearest the balloon, many of them will be induced into moving away
from the rubber balloon. By default, electrons are free to move from atom to
atom and thus there will be a mass migration of balloons side of the object to
the opposite side of the object. <span>This will leave more atoms on the rubber
balloon’s side of the object with a shortage of electrons and will be
positively charged and vice versa. </span>Overall, the object will become
electrically neutral.
Ask your self questions can help you think of what to measure, in order to get answers.
Answer:
Explanation:Systems Analysis
It is a process of collecting and interpreting facts, identifying the problems, and decomposition of a system into its components.
System analysis is conducted for the purpose of studying a system or its parts in order to identify its objectives. It is a problem solving technique that improves the system and ensures that all the components of the system work efficiently to accomplish their purpose.
Systems Design
It is a process of planning a new business system or replacing an existing system by defining its components or modules to satisfy the specific requirements. Before planning, you need to understand the old system thoroughly and determine how computers can best be used in order to operate efficiently.
System Design focuses on how to accomplish the objective of the system.
