That's a 'direct' or 'proportional' variation.
The variables are related by the equation Y = K X .
That constant ratio is the number ' K ' .
Answer:
10432.19076 m
Explanation:
= Wavelength = 660 nm
d = Diameter of pupils = 6 mm
s = Distance between lights = 1.4 m
L = Distance from observer
From Rayleigh's criteria we have
As 
is small 
So, the equation becomes
The car is 10432.19076 m from me
Formula for kinetic energy of an object:
KE = 0.5mv²
m is the mass and v is the velocity.
Formula for the work done on a charged object by moving it through a potential difference:
W = ΔVq
ΔV is the potential difference and q is the charge of the object.
To find the potential difference needed to decelerate an electron to rest, set the work done on the electron equal to its kinetic energy:
W = KE
Substitute W = ΔVq and KE = 0.5mv²
ΔVq = 0.5mv²
Given values:
q = 1.6×10⁻¹⁹C
m = 9.11×10⁻³¹kg
v = 6.0m/s
Plug in the given values and solve for ΔV
ΔV×1.6×10⁻¹⁹ = 0.5×9.11×10⁻³¹×6.0²
ΔV = 1.02×10⁻¹⁰V
