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

the charge leakage of the capacitor with a RC circuit with no voltage source and the resistance of the air between the capacitor plates. On a cold dry​ day, the resistance of the air gap is 66times×10 Superscript 131013 Upper OmegaΩ​; on a humid​ day, the resistance is 77times×10 Superscript 6106 Upper OmegaΩ. How long will it take the capacitor voltage to dissipate to half its original value on each​ day

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

What is a primary risk to the Workstation Domain, the Local Area Network (LAN) Domain, and the System/Application Domain
eimsori [14]

It should be noted that a primary risk to the Workstation Domain is the absence of a firewall and unauthorized access to the workstation.

<h3>What is a workstation domain?</h3>

The Workstation Domain simply means an individual user's computer where his or her work takes place. It should be noted that computers operating systems have vulnerability which can be susceptible to hackers.

A primary risk to the Workstation Domain is the absence of a firewall and unauthorized access to the workstation.

In a flow chart, both the decision structure and the repetition structure use the diamond symbol to represent the condition that
leonid [27]

Answer:

Option A(True) is the correct answer for the above question.

Explanation:

  • The flowchart is used to give the solution of a problem through the diagram in a step by step processor. It helps the user to understand the solution easily. For diagram, it uses many types of symbols that are fixed for every sequence just like An oval symbol represents the start and end of the flowchart which is fixed for every flowchart.
  • So for the decisions in a flowchart, the diamond symbol is used which is to make the decisions and it has two sides-- one is true and the other is false.
  • The decisions are used also to represent the loop structure which is also called the repetition structure because the loop is controlled by the help of decisions so the diamond box is also used for the loop
  • The above question-statement says that the decisions-controlled is used for the loop and for the decisions which are true because it is also described above.

Un comerciante de régimen código para comprar mercancías gravadas a un comerciante de régimen simplificado precio de venta al pú
Genrish500 [490]

Answer:

El valor sin impuestos de las mercancías era de $1.512.605.

Explanation:

Dado que un comerciante de régimen código para comprar mercancías gravadas a un comerciante de régimen simplificado pagó un precio de venta al público 1.800.000 incluido el IVA tarifa general (19%), para determinar el valor de las mercancías sin el impuesto incluido se debe realizar el siguiente cálculo:

1.19 = 1.800.000

1 = X

1.800.000 / 1.19 = X

1.512.605 = X

Por lo tanto, el valor sin impuestos de las mercancías era de $1.512.605.
