Answer:
Protraction and retraction are opposite of each other.
Explanation: For example, here are difference between the two.
1. Protraction occurs when the lower has is pushed forward to stick to the chin, Retraction, being the opposite pulls the lower jaw backward.
2. Scapular retraction, this help to move the shoulder blade(scapula) towards the spine, also Protraction being the opposite help to move the shoulder blade away from the spine.
Explanation:
A ball is thrown straight upward and falls back to Earth. It means that it is coming to the initial position. Displacement is given by the difference of final position and initial position. The displacement of the ball will be 0. As a result velocity will be 0.
Acceleration is equal to the rate of change of velocity. So, its acceleration is also equal to 0.
Hence, displacement, velocity and acceleration are zero.
Answer:
Height of mirror 0.075 m
width of mirror 0.325 m
Explanation:
given data
wide = 1.3 m
high = 0.30 m
driver’s eyes = 0.50 m
rear window = 1.50 m
solution
we take here height / width of the mirror is
height / width = .................1
and
height /width of the window is
height /width = .................2
and
distance of eye / window by the mirror is
distance of eye / window = .................3
so here
θ = θi = θr ....................4
and tanθ for vertical is
tanθ =
tanθ = ....................5
so
h = ....................6
put here value and we get
h = 0.075 m
and
when we take here tanθ for horizontal than it will be
tanθ =
tanθ = .......................7
so
....................8
put here value and we get
w = 0.325 m
