Definition of distance in physics

1 answer:

8 0

Answer:

Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.

Answer:

The distance that you marginally able to discern that there are two headlights rather than a single light source is 6.084 km

Explanation:

Given:

d = distance = 0.679 m

λ = wavelength of the light = 537 nm = 537x10⁻⁹m

dp = pupil diameter = 4.81 mm = 0.00481 m

Question: What distance, in kilometers, are you marginally able to discern that there are two headlights rather than a single light source, dx = ?

For the separation of the peak from the central maximum it is:

$sin\theta =\frac{\lambda }{d_{p} } =\frac{537x10^{-9} }{0.00481} =1.116x10^{-4}$

In this case, the two small sources of the headlights have the same angle as the images that form inside the eye

$d_{x} =\frac{d}{sin\theta } =\frac{0.679}{1.116x10^{-4} } =6.084x10^{3} m=6.084km$

$\displaystyle I = \dfrac{u}{R} \Rightarrow R = \dfrac{u}{I} = \dfrac{9 \ V}{0.45 \ A} = 20 \ \Omega. \newline
P = \dfrac{\Delta uq}{\Delta t} = Iu = 0.45 \ A \cdot 9 \ V = 4.05 \ \dfrac{J}{s} = 14580 \ \dfrac{J}{h} = 14.58 \ \dfrac{kJ}{h}.$
