Find The Current And Voltage Across Each Resistor In The Given Circuit.

Answers

Answer 1

Answer:

R1, R4: 1.3433 VR2: 0 VR3: 6.3134 V

Explanation:

The resistor R2 is shorted out, so is not in the circuit. The remaining resistors are in a series circuit with a total resistance of ...

  R1 +R3 +R4 = 1k +4.7k +1k = 6.7k

The current is the ratio of the applied voltage to this total resistance:

  I = V/R = (9 v)/(6.7k) ≈ 1.3433 mA

The voltage across each resistor is the product of this current value and the resistance:

  R1 voltage = (1 kΩ)(1.3433 mA) = 1.3433 volts

  R2 voltage = 0

  R3 voltage = (4.7 kΩ)(1.3433 mA) = 6.3134 volts

  R4 voltage = (1 kΩ)(1.3433 mA) = 1.3433 volts

If the strength of the sun's magnetic field decreased from its current level, why would the temperature of sunspots increase?

Answers

Magnetic field lines emerge from one sunspot and re-enter at the other spot. Also, there are more sunspots during periods of increased magnetic activity. At ...

The temperature of sunspots increases because magnetic field lines emerge from one sunspot and reappear in another. During periods of increased magnetic activity, there are also more sunspots.

What is the sun's magnetic field?

The magnetic field of the sun has two poles, similar to a bar magnet. Every 11 years, at the peak of the solar activity cycle, the poles flip.

The magnetic field is carried away from the sun's surface and through the solar system by a solar wind made up of charged particles. The sun is more like a fluid than a solid ball.

Thus, the magnetic field lines emerge from one sunspot and reappear in another. During periods of increased magnetic activity, there are also more sunspots.

Why are there fewer elements than there are compounds?

Answers

Compounds are 2 or more elements that are combined together to form a new substance. Why are there are more compounds than elements? Because elements can combine with more than just one element, thus creating a whole series of combination possibilities.

Because a compound is a combination of elements so you can have a variety of combinations of different elements with other elements, while an element is only 1. Therefore, an element is only account for 1 and a compound is made of 2 elements so there a multiple different combinations of compounds u can make making compounds higher in numbers than elements. Compounds are named of 2 or more elements while elements are just elements

By the time children are five years old:
A. the typical 90-minute sleep cycles of alternating REM and NREM are established.
B. about 50 percent of sleep time is spent in REM sleep and 50 percent is spent in quiet sleep that is very similar to NREM stages 1 and 2.
C. their sleep pattern is characterized by 60-minute sleep cycles, producing up to 13 cycles per day.
D. they will begin to experience their first dreams and nightmares.

Answers

Option D is correct. Around the age of five, children begin to experience their first dreams and nightmares

By the time children are five years old, several developments occur in their sleep patterns.

Option A is incorrect because the typical 90-minute sleep cycles of alternating REM (Rapid Eye Movement) and NREM (Non-Rapid Eye Movement) are not yet established at this age.

Option B is also incorrect as the sleep time distribution between REM sleep and quiet sleep (similar to NREM stages 1 and 2) is not necessarily equal at this stage.

Option C is inaccurate because 60-minute sleep cycles producing up to 13 cycles per day do not align with the typical sleep patterns of five-year-olds.

However, option D is correct. Around the age of five, children begin to experience their first dreams and nightmares.

This is an important milestone in their cognitive and emotional development, as it reflects the maturation of the brain regions involved in dreaming and the processing of emotions during sleep.

A sphere of radius r =34.5 cm and mass m = 1.80 kg starts from rest and rolls without slipping down a 30.0∘ incline that is 10.0 m long.
A.) calculate its translational speed when it reaches the bottom.
B.) Calculate its rotational speed when it reaches the bottom.
C.) what is the ratio of translational to rotational kinetic energy at the bottom?

Answers

Answer:

Explanation:

It depends on the construction of the sphere.

Let's ASSUME it is uniform construction with a moment of inertia (2/5)mR²

The Change in potential energy will equal the change in kinetic energy

mgh = ½mv² + ½Iω²

mgh = ½mv² + ½((2/5)mR²)(v/R)²

2gh = v² + 2/5v²

2gh = 7/5v²

v = √((10/7)gh)

v = √((10/7)(9.81)(10.0sin30.0))

A) v = 8.37 m/s  

B) ω = 8.37/0.345 = 24.3 radians/s

C)  ½mv² / ½Iω² = mv²/Iω² = mv²/((2/5)mR²)(v/R)² = 5/2

El cuadrado de un nmero es igual a 140 + 4 Your first assignment is to find an article talking about a scientific topic. This article can be from a source of your choosing (such as a newspaper or an internet article). You will need to include the article with your assignment. Once you have your article, you will write a short paper identifying two inferences made in this article and the facts the writer used to make these inferences. Then, elaborate on whether the two inferences made by the author are valid or more opinion-based. Be sure to include your reasoning of why you came to this conclusion. Some examples of where you can find articles about scientific topics are: The Rise of Jim CrowAlthough it failed, the Populist movement and other multi-racial efforts made the white Southern elite afraid that the poor whites and Blacks might unite to challenge the power of the plantation owners. So, in all Southern states, various laws were passed by white Southern legislatures to segregate split up Blacks and whites in Southern society. This system of segregation was nicknamed Jim Crow after a popular song and dance routine by a white man making fun of Black people.The laws were very extensive. Blacks and whites were forbidden from marrying each other. Blacks and whites had to have separate toilets, separate park benches, separate drinking fountains and restaurants. Blacks on streetcars (and later buses) were forced to sit in back and give up their seats if white passengers needed them. Of course, whites and Blacks had separate schools. The Supreme Court endorsed this segregation in the case of Plessy v. Ferguson, saying segregation was fine as long as it was separate but equal. But it was never equal. Black schools were always given less resources and less funding. Black toilets and drinking fountains were always of lesser quality. If a business could not afford separate services, they simply refused to serve Blacks. Blacks were barred from white restaurants, shops, hotels. At gas stations, Black people had to go into the woods to relieve themselves because they were not allowed to use the toilets. It was humiliating to Black people and meant to be.And it was clear that the main purpose of this segregation was not just humiliation but making sure that Blacks and whites lived in separate social circles so they would not unite as workers or as poor people. All meetings, concerts, and church services were segregated by law. A Tennessee law even forbid Blacks and whites from playing checkers together. Obviously, they had to pass these laws because Blacks and whites were mixing in these ways and it had to be stopped because if they mixed socially, poor whites and Blacks could unite politically against the wealthy elite. This situation made it difficult to form labor unions, hold strikes or demand better wages and working conditions in the South. Up until this day, the former Confederacy is the poorest part of the country. Welfare payments are the lowest. Services are the weakest. But taxes for the rich are also the lowest. This was the real purpose of Jim Crow. And although segregation itself ended after the Civil Rights Movement in the 1960s, the effects of this racist system remain today.1. What was Jim Crow?2.
