Answer:
The correct answer is 1: In Waters´ method, the head is rested on the extended chin.
Explanation:
The parietoacanthial projection (Waters' method) is a widely used radiography method that demonstrates if there are any facial bone fractures, inflammation, or foreign body in the patient skull.
The patient must be in an erect position or prone. They must rest their head on the tip of the <u>extended chin</u> against the table surface. The neck must be hyperextended so that the orbitomeatal line (OML) forms a 37-degrees angle with the plane of the image receptor (IR). This is<u> not perpendicular to IR</u>, as <u>perpendicular means</u> that a <u>90-degree angle</u> must be formed. The mentomeatal line (MML) must be perpendicular to the image receptor plane. Finally, the midsagittal plane must be perpendicular to the plane of the image receptor.
Answer:
The value that depends on another.
Explanation:
The dependent variable is the variable being tested and measured in an experiment, and is 'dependent' on the independent variable. An example of a dependent variable is depression symptoms, which depends on the independent variable (type of therapy).
The mass of the object is the sum of the masses which shows the riders:
m = 300.00 g + 20.00 g + 8.00 g
m = 328.00 g
Answer:
The mass of the object is 328.00 grams.
