two lamps (with a resistance of 10 Ohms each) are connected in a parallel circuit and are supplied with 100- volts of power. which of the following statements are true of the voltage that each lamp receives


a. Each lamp will recieve 50 volts

B. Each lamp will recieve 100 volts

C. The first lamp will recieve more voltage than the second lamp

Answers

In the parallel circuit, each lamp will receive 100 volts.

Equivalent resistance of the parallel circuit

The equivalent resistance of the parallel circuit is the inverse sum of the resistance of the two resistors in the circuit. This is as a result of different current flowing in each resistor parallel circuit arrangement.

The equivalent resistance is calculated as follows;

1/R = 1/10 + 1/10

1/R = 2/10

R = 10/2

R = 5 ohms

Current in each resistor

I = V/R

I = 100/10 = 10 A

Voltage in each resistor

V = IR

V = 10 X 10 = 100 V

Generally, for a circuit in parallel connection, same voltage will flow in each resistor of the circuit while different current will flow in the resistors.

Thus, the correct statement is, "Each lamp will receive 100 volts".

A sample of sodium hydroxide (NaOH) has a mass of 160. 0 g. The molar mass of NaOH is 40. 00 g/mol. How many moles of NaOH does this sample contain? 4. 000 moles 40. 00 moles 160. 0 moles 6,400 moles.

Answers

4 moles of NaOH is present in the given 160 grams of NaOH.

How we calculate moles?

Moles of any substance will be calculated as:

n = W/M, where

W = given mass of NaOH = 160 grams (given)

M = molar mass of NaOH = 40 g/mole

Moles of NaOH is calculated as:

n = 160g / 40g/mol = 4 moles

Hence, moles of sodium hydroxide (NaOH) is 4 moles.

Answers

Answer:

The answer is 16.12 L  

Explanation:

2.5 * 20 = 3.1 * V2

V2 = 50/3.1

V2= 16.12 L

hope this helps

The new volume can be calculated using Boyle's law. If the pressure increases from 2.5 atm to 3.1 atm, then volume decreases from 20 L to 16.1 L.

What is Boyle's law ?

Boyle's law is a fundamental law of physics that describes the relationship between the pressure and volume of a gas at a constant temperature. It is named after the Irish physicist Robert Boyle, who first stated the law in the mid-17th century.

Boyle's law states that at a constant temperature, the pressure of a gas is inversely proportional to its volume. This means that as the volume of a gas decreases, its pressure increases proportionally.

Hence,

P1V1 = P1V2.

given,

P1 = 2.5 atm

V1 = 20 L

P2 = 3.1 atm

then V2 = P 1 V1 /P2

V2 = 2.5 atm × 20L/3.1 atm = 16.1 L.

Therefore, the new volume of the gas is 16.1 L.

What is a lunar eclipse?

A lunar eclipse usually takes place when the Moon moves into the shadow of the earth. This eclipse happens only when the Sun, Earth, and Moon are exactly aligned with Earth between the other two, which can occur only on the night of a full moon when the Moon is close to the lunar node.

When the moon is eclipsed by the Earth, it gets on a reddish color that is caused by the planet when it fully blocks direct sunlight from reaching the Moon's surface, as only the light reflected from the lunar surface has been refracted by the atmosphere of the earth. Due to the Rayleigh scattering of blue light, this light appears reddish.

A total lunar eclipse lasts up to nearly 2 hours, lunar eclipses are safe to view. Therefore, image 2 represents the lunar eclipse.

Answers

Answer:

T2 = 242.06

Explanation:

Follow this equation to find T2: V1/T1 = V2/T2

V1 = 9.3L

T1 = 27C (to convert to Kelvin + 273.15) ---> 27 + 273.15 = 300.15K

V2 = 7.5L

T2 = ?

V2×T1/V1 = T2

Beginning in their adolescent years, students' sleep patterns change because they become more focused in the evening and stay up later. This requires that they sleep later in the morning since, according to research, teenagers need 810 hours of sleep. Not getting enough sleep can lead to health risks, but it also has consequences for teenagers and their academics. Students who do not get enough sleep have a harder time staying alert and remaining focused in class, which can lead to poorer grades. Furthermore, lack of sleep can lead to increased stress levels and prevent students from retaining information, leading to problem-solving troubles. Teenagers who do not get enough sleep suffer from poor academic performance. Physical problems, such as lack of physical alertness, can also be the result of teenagers not getting adequate sleep. Research also shows that students who do not get enough sleep can be overweight. While many middle and high schools begin before 8:30, they should modify their schedules. Experts suggest that these schools begin no earlier than 8:30 in the morning. This allows for students to sleep later in the morning, which matches the scientifically proven sleep cycles of teenagers. Question: Which sentence would be the best conclusion to the essay? a The needs of students should not be the driving force behind schools modifying schedules. b Allowing students to sleep in will benefit schools and later start times should be put in place. c For students to be successful, schools should understand the importance of students' physical needs. d Middle and high school students cant stay focused if they dont have enough sleep.
