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

What is a product of respiration

Explanation:
What is the average rate of change of h(x)=2^{x+1}h(x)=2 x+1 h, (, x, ), equals, 2, start superscript, x, plus, 1, end superscript over the interval [2,4][2,4]open bracket, 2, comma, 4, close bracket?
Answer:
Average Rate = 12
Explanation:
Given
h(x) = 2^(x + 1)
Interval = [2,4]
Required
Determine the average rate of change
The average rate of change of h(x) is calculated using.
Average Rate = (h(b) - h(a))/(b - a)
Where
[a,b] = [2,4]
Meaning a = 2 and b = 4
So, the formula becomes:
Average Rate = (h(4) - h(2))/(4 - 2)
Average Rate = (h(4) - h(2))/2
Average Rate = ½(h(4) - h(2))
Calculating h(4)
h(4) = 2^(4+1)
h(4) = 2⁵
h(4) = 32
Calculating h(2)
h(2) = 2^(2+1)
h(2) = 2³
h(2) = 8
So, we have:
Average Rate = ½(h(4) - h(2))
Average Rate = ½(32 - 8)
Average Rate = ½ * 24
Average Rate = 12
Hence, the average rate of change is 12

Explain what iteration is and why we need it in code
Answer:
Explanation:
When a cycle of instructions is carried out in a repeated manner, it is called a loop. It is the replication of a process in a computer program, commonly executed with the use of loops. Iteration is essential as it lets a programmer streamline a design by declaring that definite steps will be repeated.

because ergonomics is trying to make the person who is using the device be in a more natural position. Raising the keyboard will make the typer feel more comfortable.
Elevating keyboard, so wrists are bent when typing of the following is considered proper ergonomics. Thus, option (a) is correct.
What is ergonomics?Human factors ergonomics, as it is known in North America, is an area of research that seeks to learn understanding people intelligence and constraints and then utilize this knowledge to improve people's interactions with things, systems, and surroundings.
Raising the keypad and bending the wrists when typing, according to ergonomics, are employed to place the person using the computer in a more favored role. Moving the keyboard relaxes the typer. Wrist supports are commonly seen on keyboards and keyboard trays to help keep your wrists in a normal, virtually straight position.

Jason has decided to use his name on all the images to protect them from misuse. He has also decided to use the logo of his company across all
the images to be extra sure about its protection in the digital world. Select the phrases or sentences that describe the two types of watermarking
options has he used to get the results.
Types of Watermarking Options
Jason wants to tag his name or logo somewhere on the image, preferably in the corner of the photo. He uses an online editing tool to add his
name at the corner of the image. He can prevent misuse of his Images online by adding a watermark over the image. Text watermarking
involves adding the imageer's name at the corner of the image. This is usually done with the help of online editing tools or software. In this form
of watermarking, he can use the logo of his company over the image to protect his identity.
Just to be sure, Jason also uses tiled watermarking, which involves placing his company logo in a pattern spread across the image. First, he
creates a copy of the original. This is to make sure that the watermarked version is saved separately. If needed, he can always access the
original image. Then he opens the logo that he wants to use as the watermark, coples It, and pastes it onto a new layer, above the image. He
turns down the opacity of the layered image. Then he merges the layer to join the watermark with the image.
