What rule of magnetism is illustrated by the lines of the iron filings with unlike poles?
Debora [2.8K]

Answer:

The rule of magnetism illustrated is the field lines are more concentrated at the poles and also about the direction of magnetic field.

Explanation:

  • Every magnet has two pole, north pole and south pole. The like poles repel each other and unlike poles attract each other.
  • The direction of magnetic field is from north to south that can be seen by the iron filling experiment.
  • When the iron fillings are kept near the bar magnet, we observe that most of the fillings are attached to either poles.
  • It is due to the fact that the concentration of magnetic field is highest at the poles.

On a clinical rotation, you encounter Mr. Kalani, who has left sided heart failure. This means that the left side of his heart i
const2013 [10]

In the case of left-sided heart failure, blood backs up into the lung circuit. You would expect Mr. Kalani to have pulmonary direct result of this edema.

<h3>The effects of Left-sided heart failure</h3>

Left-sided heart failure occurs when the heart becomes unable to pump blood to the whole body. This is because the heart can not handle the blood that is coming from the lungs.

When left-sided heart failure occurs, fluid leaks from the affected capillaries into the nearby tissues of the lungs circuit leading to pulmonary edema.

Excess fluid in the tissues is called edema and in the case of a left-sided heart failure, other parts of the body such as the feet, legs and ankle are equally swollen.

Which statements describe planetesimals? Select three options. They are the origins of planets. They formed from gas and dust. T
Anika [276]

A solid minute object that is said to come together for the formation of the planet and are believed to produce cosmic dust are called planetesimal.

The options that best describes the planetesimals are:

  • Option A. They are the origins of planets.

  • Option B. They formed from gas and dust.

  • Option D. They are believed to have developed in debris disks.

The descriptions can be explained as:

  • It is believed that planets formation occurred through planetesimals. The formation happened from gas, dust particles and debris.

  • By the process of accretion, the discs coalesced and became bigger and solid over time. This bigger mass started attracting other matters towards each other because of gravitational force.

  • This pull resulted in either breaking or creation a bigger mass of pieces known as planetesimals. The collision continued to become bigger and solid planets we know today.

Therefore, options A, B and D are correct.

Biologists notice that a population of ferrets introduced into a reserve begins to show exponential growth. The figures represen
sesenic [268]

Answer:

A. 50, 88, 145, 227

Explanation:

The correct option would be option A.

<u>When something grows exponentially, it means the growth increased at a high rate. More specifically, each rate of increase results in more or less doubling of the preceding rate. For example, if the current value of growth rate is 2 for a substance that is growing exponentially, the next growth rates will be 4, 8, 16, etc.</u>

<em>In this particular illustration, the only option that best fit into an exponential system is option A in which the growth rate more or less doubles each time from 50 to 88, from 88 to 145, and then from 145 to 227.</em>
