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

Identify a true statement about decision support systems (DSSs).

Zolol [24]

Answer:

a. facilitate improvements but do not necessarily cause them.

Explanation:

Decision Support Systems are interactive Information systems that assist decision makers in coming up with strategies that help the organisation achieve its goals .The model base of the DSS uses mathematical and statistical models to analyse information then it generates reports and suggest possible solutions that can be implemented .The system is capable of giving a specific solution and some even allow the decision makers to give input before suggesting the most applicable solution.The effectiveness of a DSS is equally as important as its efficiency .The DSS unlike the conventional decision-making process should be able to analyse information effectively and come up with solutions in the shortest possible time frame.

Modify the WordCount program so it outputs the wordcount for each distinct word in each file. So the output of this DocWordCount

stepladder [879]

Answer and Explanation:

package PackageDemo;

In the Microsoft publisher application, words underlined in red are ____.

nydimaria [60]

In the Microsoft publisher application (as well as many other websites such as Brainly, Google docs, etc), words underlined in red are spelled incorrectly.

Whether you spelled it incorrectly or did not complete the words, as long as the word is not found in the dictionary, the word would be underlined with a red squiggly line.

Tanzania [10]

Answer: Java and Forth

Explanation:

C ++ and Java are comparatively similar language which are composed statically, unequivocally, and obviously. Both language are the object-oriented and planned with the semi-interpretation and run-time during the compilation of the time.

Both uses the curly braces and also they are very similar language as compared with c# and c. Both the successors in the C++ , java and sun micro-system are similar in terms of Microsoft.
