A 10 Superscript negative 910−9​-F capacitor ​(11 nanofaradnanofarad​) is charged to 5050 V and then disconnected. One can model
vredina [299]

Answer:

Explanation:

i) On a cold day, Capacity = (66 X 910 X 10∧-9) F

Charge, Q = (66 X 910 X 10∧-9) X 5050 = 0.30 Columb

Current, I= 5050/131013 = 0.039 Amp (where Resistance = 131013 ohms)

Time, t= 0.30/0.039 = 7.7 seconds

ii) On a humid day, Capacity = (77 X 910 X 10∧-9) F

Charge, Q = ( 77 X 910 X 10∧-9) X 5050 = 0.35 Columb

Current, I= 5050/6106 = 0.83 Amp ( where Resistance = 6106 ohms)

Time, t= 0.35/0.83 = 0.42 h or  0.42 X 60 mins = 25 mins

Advantages and disadvantages of algorithm​
Maru [420]

Answer:

\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\

Explanation:

It is easy to understand. Algorithm is a step-wise representation of a solution to a given problem. In Algorithm the problem is broken down into smaller pieces or steps hence, it is easier for the programmer to convert it into an actual program

Algorithms are time-consuming. Big tasks are difficult to put in algorithms. Difficult to show branching and looping in algorithms. Understanding complex logic through algorithms can be very difficult.

The listing of a directory shows certain files with permissions set to rwsr-xr-x. what does this indicate?
marta [7]
<span>"rws" means that the user has permissions to read, write and setuid. "r" means the user can read the file and "w" means that the user can write to the file. "s" stands for "setuid" (set user id) is a permission bit that allows the users to execute a program with the permissions of its owner. The "s" can also mean "setgid" (set group id) is a bit that allows the user to execute a program with the permissions of the group owner.</span>
