A bus slows down uniformly from 21 m/s to a complete stop in 21 seconds. How far did the bus travel before stopping?

Answers

Answer 1

Answer: $velocity_(final)-velocity_(initial)=(distance)/(time)\n\n v_(initial)=21(m)/(s)\n v_(final)=0(m)/(s)\n time=21s\n\n \Delta v *time=distance\n\n distance=|(0-21)*21|=441m \n\nBus\ traveled\ 441meters.$

A dryer runs on 240 V with a resistance of 30.0 Ω. What is the current of the dryer?

Answers

Answer:

Current, I = 8 Amps

Explanation:

Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

$V = IR$

Where;

V represents voltage measured in voltage.

I represents current measured in amperes.

R represents resistance measured in ohms.

Given the following data;

Resistance, R = 30 ohms

Voltage, V = 240V

To find the current;

$I = \frac {V}{R}$

$I = \frac {240}{30}$

Current, I = 8 Amps

Therefore, the current of the dryer is 8 Amperes.

The electron configuration of nitrogen (N) is

Answers

Answer: $1s^22s^22p^3$

Explanation:

Electronic configuration represents the total number of electrons that a neutral element contains. We add all the superscripts to know the number of electrons in an atom.

The electrons are filled according to Afbau's rule in order of increasing energies and thus the electronic configuration for nitrogen with atomic number of 7 which also contains 7 electrons is:

$N:7:1s^22s^22p^3$

The electron configuration of (N) is 1s²2s²2p³

What is nonexample of distance

Answers

a non example of distance is capacity , volume , temperature , time , weight , power , velocity , energy , pressure , and angle

Final answer:

A nonexample of distance refers to statements or information that do not provide quantitative information about the length between two points.

Explanation:

A nonexample of distance would be something that does not involve measuring the length between two points. For example, when talking about the distance between two cities, saying 'I like the weather there' would be a nonexample because it does not provide any quantitative information about the distance. Similarly, if we are measuring the distance a car travels, saying 'It is a red car' would also be a nonexample as it does not relate to the measurement of distance.

What was the duration of the last and longest manned mission to Skylab?

Answers

The last duration of the longest manned mission to Skylab is 84 days and 1 hour.

Final answer:

The last and longest manned mission to Skylab is a notable point in history of space exploration, but the specific duration is not stated in the provided references.

Explanation:

In regard to the question, "What was the duration of the last and longest manned mission to Skylab?", the Skylab missions were part of a significant chapter in U.S. space exploration history during the 1970s. However, the provided reference material does not offer specific information about the duration of the last and longest manned mission to Skylab. Skylab was an important part of American space research, serving as a space station where numerous scientific experiments were conducted. Yet, without the specific details, it is difficult to provide an accurate response to this particular query. The Skylab program, operated by NASA in the 1970s, had its last and longest manned mission known as Skylab 4. The Skylab 4 mission launched on November 16, 1973, and lasted for a total of 84 days, with the crew returning to Earth on February 8, 1974. The crew consisted of Gerald Carr, Edward Gibson, and William Pogue. This mission set a record for the longest manned spaceflight at that time, spending an extended period aboard the Skylab space station for scientific research and experiments.
