Answer:
Kinematics is the motion of objects without reference of forces that causes the motion in objects.
Explanation:
Hannah comes to a rest in <em>t</em> = 0.4 s, so her acceleration is
<em>a</em> = (0 - 25 m/s) / (0.4 s) = -62.5 m/s²
(that is, the acceleration points in the direction opposing her movement forward as she brakes)
Then the force exerted on her by the seatbelt has magnitude
<em>F</em> = (65 kg) (62.5 m/s²) = 4062.5 N ≈ 4063 N
Question:
When salt dissolves in water, what type of change occurs?
Answer:
A physical change results in a change of the material's appearance, but no new chemical products result. So the answer would be A.
