Verdich [7]

Efficiency

Explanation:

Efficiency is a ratio/percentage that is useful in comparing the energy transferred by a device to the total energy supplied to it.

Percentage efficiency = $\frac{energy input}{total energy supplied}$ x 100

As with most system, none is 100% efficient.
During energy is transferred some are lost and only a little portion is used in doing actual work by the machine.
This validates the third law of thermodynamics which proposes that no system is 100% efficient.
A 100% efficiency implies total energy input is used doing all the work.
This is impossible. The bulk of the energy goes into heating the system.

Andrews [41]

Answer:

10432.19076 m

Explanation:

$\lambda$ = 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

$1.22\lambda=dsin\theta$

As $\theta$ is small $sin\theta=\dfrac{s}{L}$

So, the equation becomes

$1.22\lambda=d\dfrac{s}{L}\\\Rightarrow L=\dfrac{ds}{1.22\lambda}\\\Rightarrow L=\dfrac{6\times 10^{-3}\times 1.4}{1.22\times 660\times 10^{-9}}\\\Rightarrow L=10432.19076\ m$

The car is 10432.19076 m from me
