Answer: 0.075
explanation:
you can use one of the equations of motion.
2as =v^2 - u^2
we shall make acceleration the subject as that's what we need to find out
a = (v^2 - u^2) / (2 × s)
now substitute the given values:
final speed would be zero as the airplane stops.
a = (75 - 0) / ( 2 × 500)
a = 75 ÷ 1000
a = 0.075 meters per second squared.

Answer:
a) n2 = 1.55
b) 408.25 nm
c) 4.74*10^14 Hz
d) 1.93*10^8 m/s
Explanation:
a) To find the index of refraction of the syrup solution you use the Snell's law:
(1)
n1: index of refraction of air
n2: index of syrup solution
angle1: incidence angle
angle2: refraction angle
You replace the values of the parameter in (1) and calculate n2:

b) To fond the wavelength in the solution you use:

c) The frequency of the wave in the solution is:

d) The speed in the solution is given by:
