In the circuit described by the diagram, which pair of resistors is connected in parallel?
scoundrel [369]

Option 4 ( R2 and R3 ) is the correct answer.

Explanation:

  • In the below given diagram, we can see a circuit diagram that has four resistors such as R1, R2, R3, and R4.
  • The opening of the circuit is noted as "a" and the ending is noted as "b".
  • By observing the above diagram, we can clearly see that R2 and R3 are the pair of resistors that are connected in a parallel manner.
  • Where all the other resistors such as R1 and R4 are neither connected in parallel nor in series.

Hence we can conclude that Resistor R2 and R3 are the ones that are connected in parallel.

When conducting a search to identify a text's credibility and reliability, you have to check the following characteristics:

  • Sources: where the information is obtained and it is supposed to be true. It is said that you need at least three different sources that explain the same information for it to be validated.

  • Is the article is current?: articles could change all the time, specially scientific ones because new discoveries can change what was discovered before, so it is important to check if the text you are reading is current or not, and if it is not, you need to check if something has changed during all those years.

<h3>Article's credibility</h3>

In this exercise, you have to present an article and describe the purpose of the source and if the article is current or not.

For example, let's select an article called "How using social media affects teenagers".

The purpose of the sources in this article is to demonstrate how social media affects teenagers using different surveys.

A car travels 554 miles south in 10.4 hours . what is the velocity of the car ? show all steps
kirill115 [55]

Answer:

<h3>The answer is 53.27 mi/hr</h3>

Explanation:

To find the velocity covered by the car we use the formula

v =  \frac{d}{t}  \\

where

d is the distance

t is the time

From the question

d = 554 miles

t = 10.4 hrs

We have

d =  \frac{554}{10.4}  \\  = 53.2692307...

We have the final answer as

<h3>53.27 mi/hr</h3>

Hope this helps you
