Answer:
Explanation:
Gliding joint (plane joint or planar joint,) is a synovial joint formed by two flat bones surfaces joined together by ligaments. This allows for flexibility in any direction along the bone such as sliding, twisting, bending, stretching and circular (rotation) movements. The synovial fluid between the bone surfaces reduces friction at the joint.This type of joints can be found in the human body at the wrist, foot, palm, ankle.
Based on the information given, it should be noted that a 95% confidence means we are at least 95% sure that the true value of proportion will lie in the interval.
<h3>
What does the confidence level mean?</h3>
When we repeat the sampling 100 times and draw a confidence Interval for each one of them, at least 95 confidence intervals will contain the true value of the proportion. This is what we mean by being 95% confident
Also, when we have a random sample of 5. It implies that the condition of randomness is met and they are independent as well. Since the sample size is very small, the condition of a large sample is not satisfied.

Answer:
If these mixtures are impure, it is certain that these can pose a greater risk related to health conditions by exploding abruptly.
Explanation:
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.
