Differences:
<u>Reflection</u> is described as the reverting back of light or sound waves in the same medium, when it falls on plane.
<u>Refraction</u> means the shift in direction of the radio waves, when it enters medium with different density.
Comparisons:
<u>Reflection and refraction</u> <em>both</em> change the direction of light and both <em>do not </em>absorb light. All light waves can be reflected and refracted.
Both <u>Reflection and Refraction</u> are phenomenon related with wave motion of sound, and electromagnetic waves, thus including light.
They are the same. If this is all happening on Earth, then the ball's acceleration is 9.8 m/s^2 in either case. That's the acceleration of gravity around here.
Is this multiple choice because i dont see it
Answer:
This is Newton's second law.
<u>Newton's second law text:</u>
(If a resultant force acts on a body, then an acceleration will give it an acceleration, the magnitude of which is directly proportional to the amount of the net force, and a direction is in the direction of the net force itself)
F=ma
net force = mass x acceleration
I hope I helped you^_^
