It would be D. Hi ok my guy
The statement which describes this phenomenon is; Electrons flow freely into the magnetic field, causing the paper clips to move.
<h3>Metals and the Electromagnetic field</h3>
- Metals are made up of positively charged atoms of elements in which case the outermost orbital of these metal atoms contain electrons revolving round them.
On this note, upon interaction with the electromagnetic field posed by an electromagnet placed nearby, it follows that;
- The Valence electrons flow freely into the magnetic field created by the electromagnet and hence, causes the paperclip to move.
The complete question contains options given are;
Metal paper clips do not attract or repel each other. When an electromagnet is placed nearby, the paper clips can be observed to move toward it. Which statement describes this phenomenon?
- Paper clips turn into permanent magnets after exposure to a magnetic field.
- The electromagnet reacts to the strong force of attraction from paper clips.
- Electrons flow freely into the magnetic field, causing the paper clips to move.
- Magnetic domains within the paper clips align with the magnetic field.

Based on the information given, the interpretation of the confidence level will be that ninety percent of the time, the procedure used to generate this interval will capture the true proportion of teenagers who drive their own car to school.
<h3>
What is confidence level?</h3>
A confidence level simply means the percentage of probability that then m confidence interval will contain the true population parameter when the person draws a random sample.
It should be noted that a 90% confidence interval means a range of values that the person is 90% sure contains the true mean of the population.

Answer:
Physical weathering is most active where temperature and rainfall are both low. Chemical weathering is most active in regions of high temperature and rainfall. Most world regions experience a combination of both physical and chemical weathering.
