How long does it take for an acorn to drop from the branch of a tree 10.0 m high and hit the ground, assuming no air resistance? Remember, rest is the initial velocity and it equals 0.0 m/s.
O 1.0 s
O 1.4 s
o 4.95
O 9.8 s

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).
