Final answer:
Angle Class II Division 2 is a classification system used in orthodontics to describe a specific type of malocclusion (misalignment of the teeth and jaws).
Step-by-step explanation:
The correct answer is option Health. Angle Class II Division 2 is a classification system used in orthodontics to describe a specific type of malocclusion (misalignment of the teeth and jaws). In Angle Class II Division 2, the upper front teeth are positioned more towards the back of the mouth, with the lower front teeth often being behind the upper front teeth.
This type of malocclusion can be caused by various factors, such as genetics, abnormal tooth eruption, or habits like thumb sucking.
The correct answer is option Physics. In the context of physics, particularly when discussing scattering or motion in a two-dimensional plane, angles are typically measured from the positive x-axis in the counterclockwise direction.
When an object such as mass m₂ is scattered to the right and the angle is described as being in the fourth quadrant, it indicates that m₂ has a positive x-direction (to the right) and a negative y-direction (downwards).
To solve for the velocity v'2 after the scattering, one can use the equation for the x- or y-axis. However, the y-axis equation might be simpler as it often contains fewer terms making the calculations more straightforward.
This is an example of using kinematic equations to solve for unknown variables in a physics problem involving motion in two dimensions.
