To solve this problem it is necessary to apply the concepts related to angular resolution, for which it is necessary that the angle is
Where
d = Diameter of the eye
n = Index of refraction
D = Distance between head lights
= Wavelength
Replacing with our values we have that
Using the proportion of the arc length we have to
Where L is the maximum distance, therefore
Therefore the maximum distance from the observer that the two headlights can be distinguished is 12.77km
Answer:
d = 2*0.87 = 1.75 cm
Explanation:
by using flow rate equation to determine the speed in larger pipe
= 591.10 cm/s
= 5.91 m/s
by Bernoulli's EQUATION
solving for v2
v2 = 10.53 m/s
diameter can be determine by using flow rate equation
r = 0.87 cm
d = 2*0.87 = 1.75 cm
