Write a program to compute the total power generated by a klink circuits, where the n is entered by the user, for each circuit ask for the input phase angle, compute the power and add that power to the total, each time you ask the user to enter the phrase angle, if the user does not enter a number between 0 and 90 display an error message and ask them again until they enter a valid if the entry is not valid, then do not compute the power and do not count that as one of the n circuits, also check for a positive number for the n - the number for circuits. display the total power(and do not display the cumulative total after each circuit)

the power generated by a klink circuits
p=kcos(aπ/180)

where
p = power(killowats, k w)
k = klinks constant (5/7)
a = phase angle (in degrees)
π = pi (3.

You have a linux system that has a 1000gb hard disk drive, which has a 90gb partition containing an ext4 filesystem mounted to the / directory and a 4gb swap partition. currently, this linux system is only used by a few users for storing small files; however, the department manager wants to upgrade this system and use it to run a database application that will be used by 100 users. the database application and the associated data will take up over 200gb of hard disk space. in addition, these 100 users will store their personal files on the hard disk of the system. each user must have a maximum of 5gb of storage space. the department manager has made it very clear that this system must not exhibit any downtime as a result of hard disk errors. how much hard disk space will you require, and what partitions would you need to ensure that the system will perform as needed? where would these partitions be mounted? what quotas would you implement? what commands would you need to run and what entries to /etc/fstab would you need to create? justify your answers.
