Resposta:
Per a càrrega de 680Ω: 7,27 volts
Per a les dues càrregues de 220Ω: 2,36 volts cadascuna
Explicació:
Segons la llei d’ohms
E = IRt
E és la força electromotriu = 12V
I és el corrent total que circula al circuit
Rt és la resistència equivalent total
Com que els 680Ω, 220Ω i 220Ω estan en sèrie;
Rt = 680 + 220 + 220
Rt = 1120Ω
Obteniu el corrent total del circuit:
Recordem que: E = IRt
I = E / Rt
I = 12/1120
I = 0,0107A
Tingueu en compte que el mateix corrent flueix a través de resistències connectades en sèrie, però tensions diferents.
Obteniu les tensions individuals;
Per a càrrega de 680Ω;
V = IR
V = 0,0107 * 680
V = 7,27 Volts
Per a la càrrega de 220Ω
V = IR
V = 220 (0,0107)
V = 2,36 volts
Per tant, les tensions de les dues càrregues de 220Ω seran de 2,36 volts cadascuna

Select all the correct answers. Which two statements are true about electric current through a circuit? Current flows from a positive terminal to a negative terminal. Current flows through an open circuit. Electrons flow from a positive terminal to a negative terminal. Electrons flow in the same direction as current. Electrons flow from a negative terminal to a positive terminal.
Answer:
Current flows from a positive terminal to a negative terminal.Electrons flow from a negative terminal to a positive terminal.Explanation:
Indeed, it is a proven and generally accepted fact that electric current flows away from a positive terminal to a negative terminal. This is the case because the positive terminal of an electric circuit is under the pushing influence of the electric field, hence it moves to the negative terminal.
While electrons in an electric circuit flow from a negative terminal to a positive terminal. In other words, they move in the opposite direction of the current through the wires.

Big Bob's Construction has many construction sites where computers are located. At the remote sites, Internet connectivity can be of poor quality and intermittent. Because the computers are onsite and have poor connectivity to the main office, they are not currently domain joined. However, they could be domain joined if required. You want to be able to manage the computers at the construction sites. Which technology can allow you to do this and not force users to reconnect constantly?
Answer:
WAN or wide area network using satellite
Explanation:
A WAN or wide area network is a network of local area networks that could span beyond a geographical region.
For a network administrator to manage the remote construction site, a stable network connection should be established using a wireless medium like a satellite to connect the site's network to the office network.

A ___________search can be done on a list that is not ordered.
Answer:
Well, a binary search has to be ordered. So ima just say linear search..
Explanation:
I think its linear..
A binary search can be done on a list that is not ordered.
What is a binary search?Binary search is a fast technique that finds an item from a sorted list of objects with a run-time complexity of O(log n), where n is the total number of elements. Divide and conquer concepts are used in binary search.
When performing a binary search on an array in computer programming, the array must be sorted in ascending order, i.e. from the least to the highest with respect to the data value.
The primary benefit of using binary search is that it does not scan every element in the list. Instead of scanning each element, it searches the first half of the list. As a result, a binary search takes less time to find an element than a linear search.
Therefore, the correct option is b, Binary.
