<span>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.

Given that it takes 0.08 ms to travel from one track to the next of a hard drive; that the arm is originally positioned at Track
daser333 [38]

Answer:

Time taken to travel from one track to the next = 0.08ms

Initial track= 15     0

4      (15-4)*(0.08)= 0.88

40     (40-4)*(0.08)= 2.88

35      (40-35)*(0.08)= 0.4

11       (35-11)*(0.08)= 1.92

14       (14-11)*(0.08)= 0.24

7         (14-7)*(0.08)= 0.56

----------------------------------------------

Total seek time=0.88+2.88+0.4+1.92+0.24+0.56=6.88ms

Explanation:

We caculate the seek time for each request, and then add them together to find the total seek time. The final track number for the current request becomes the current track of next request, and this process is repeated till the last request is processed.

Giving reasons for your answer based on the type of system being developed, suggest the most appropriate generic software proces
soldi70 [24.7K]

Answer:

For the university accounting system that replaces an existing system the appropriate generic software process model is Waterfall model

This is because the requirement of the system can be predicted in advance because of the existing system and secondly, this a mission critical system and the requirement are stable and reusable

For the  interactive travel planning system that helps users plan journeys with the lowest environmental impact the appropriate generic software process model is Prototype Model

This is because the user's requirement may likely change and fast delivery is essential to be implemented and for this the prototype model can save time of development to focus on essential functions first.

Explanation:

In order to get a better understanding of the answers above let define the concept of

Waterfall Model:

   We can define waterfall model as a type of software development approach that explains step by step development method, this software development approach consist of five to seven steps and each step is characterized by different tasks and objectives and these steps combined together explains the the life cycle of the the software development process.

Prototype Model

   We can define prototype model as a type of system development approach whereby an estimation(i.e the prototype) of the final system is constructed,tested and adjusted until the desired result is obtained and the the main system is then constructed with the specification of the perfect estimation or prototype for example when constructing a bridge the engineer apply this methodology by first constructing an estimation or prototype of what the bridge should look like and then various test and adjustments are  been carried out on this prototype bridge afterward he main bridge is been constructed with the specification of the prototype.
