Horizontal angulation is Select one: a. the side-to-side angulation. b. different when using the paralleling and bisecting techniques.
Angles that are horizontal. relates to the central ray's placement in a horizontal, or side-to-side, plane.
A picture with an overlap of nearby structures in the horizontal plane is produced by situating the central ray such that the horizontal angulation is not directed through the interproximal contacts of the adjacent teeth (the contact areas of the teeth are superimposed over each other).
Fracture angulation refers to a particular kind of fracture displacement in which the bone's natural axis has been changed so that the distal end now points off in a different direction. When using a bite-wing tab, the x-ray beam's center ray must be pointed at the contact points between teeth. The x-ray beam must be centered on the receptor to guarantee that the receptor is exposed.

Answer:
-0.4 m/s
-3.552 m/s
Explanation:
= Mass of first glider = 0.5 kg
= Mass of second glider = 0.3 kg
= Initial Velocity of first glider = 2 m/s
= Initial Velocity of second glider = -2 m/s
= Final Velocity of first glider
= Final Velocity of second glider = 2 m/s
As the linear momentum of the system is conserved we have
The velocity of glider A is -0.4 m/s
= 0
= -5 m/s
= 0.92 m/s
The velocity of glider A is -3.552 m/s
If A is the measurement in the x-axis and B is the direction in the y-direction,
Magnitude = √(1.5² + (-3)²)
Magnitude = 3.35 units
Direction:
tan∅ = y/x
tan∅ = 3/1.5
∅ = 63.4°
Tan is negative in the second and fourth quadrants, and the values of x and y indicate that it is in the fourth quadrant. Therefore, the direction is 63.4° below the positive x-axis.
The rock is kicked horizontally off the cliff at 20 m/s.
There's no air resistance, and gravity has no effect on horizontal motion. There's no horizontal force acting on the rock to make it move horizontally slower or faster than 20 m/s, so it keeps moving horizontally at 20 m/s.
It's in the air for 7 seconds before it hits the ground. Moving horizontally at 20 m/s for 7 seconds, it sails (20 x 7) = 140 meters horizontally away from the cliff.
