4. Compara. La composición de la gasolina para los coches cambia del invierno al verano. La mezcla de los componentes de la gaso

lina debe evitar problemas en su vaporización en los cilindros del motor. Por eso, las compañías petrolíferas preparan distintas mezclas para el invierno o para el verano: una de las mezclas tiene más componentes volátiles que la otra. Argumenta cuál tendrá más componentes volátiles en su composición y qué problemas surgirían si se emplearan al revés, la de invierno en verano y la de verano en invierno.

Natalka [10]

There are problems with the first sentence, and it's not really needed when
working with this question.  So let's just take the 20 (Hz ?) frequency from
the first sentence, and ignore the rest of it for right now.

           Wavelength = (speed) / (frequency) =

                                   (331 m/s) / (20 Hz) = <em>16.55 meters</em>.

Visible light passes through a diffraction grating that has 900 slits per centimeter, and the interference pattern is observed o
love history [14]

Answer:

13.51 nm

Explanation:

To solve this problem, we are going to use angle approximation that sin θ ≈ tan θ ≈ θ where our θ is in radians

y/L=tan θ ≈ θ

and ∆θ ≈∆y/L

Where ∆y= wavelength distance= 2.92 mm =0.00292m

L=screen distance= 2.40 m

=0.00292m/2.40m

=0.001217 rad

The grating spacing is d = (90000 lines/m)^−1

=1.11 × 10−5 m.

the small-angle

approx. Using difraction formula with m = 1 gives:

mλ = d sin θ ≈ dθ →

∆λ ≈ d∆θ = =1.11 × 10^-5 m×0.001217 rad

=0.000000001351m

= 13.51 nm
