A deviated nasal septum occurs when the partition between the two nostrils is pushed to one side, leading to a partially obstructed airway in one nostril.
So the magnitude of the resultant vector of the vertical and horizontal together is a right triangle with 20 on one side and 19.62 going down.
<span>A^2 + B^2 = C^2 </span>
<span>20^2 + 19.62^2 = C^2 </span>
<span>400 + 385 = C^2 </span>
<span>C = 28.0 m/s magnitude </span>
Answer:
physical change
Explanation:
its a physical change because its still soda it hasn't changed into anything else than what it already is
The car travels a distance <em>d</em> from rest with acceleration <em>a</em> after time <em>t</em> of
<em>d</em> = 1/2 <em>a</em> <em>t</em>²
It covers 69 m with 2.8 m/s² acceleration, so that
69 m = 1/2 (2.8 m/s²) <em>t</em>²
<em>t</em>² = 2 (69 m) / (2.8 m/s²)
<em>t</em> ≈ 7.02 s
where we take the positive square root because we're talking about time *after* the car begins accelerating.
