charle [14.2K]

Mario Molina helped to bring about the 1987 Montreal Protocol on substances that result in depletion of the Ozone Layer.

<h3>What is ozone layer?</h3>

The topmost layer of the atmosphere which protect the harmful UV rays from the Sun to reach the Earth surface.

Mario Molina has the great contribution in science field. He tried hard and succeeded in passing an international agreement to eliminate CFCs also called as Chloro Fluoro Carbons and other ozone-depleting chemicals.

These CFCs were used in jet planes which depleted the ozone layer and a hole was observed over Antarctica.

A ski resort consists of a few chairlifts and several interconnected downhill runs on the side of a mountain, with a lodge at th
Aleks04 [339]
  1. A sketch of the junction between one chairlift and two runs is shown in the image attached below.
  2. For this ski resort, it ultimately implies that the total number of lifts that are used in any closed loop would be equal to zero in accordance with Kirchhoff's loop rule.

<h3>What is Kirchhoff's loop rule?</h3>

Kirchhoff's loop rule is also referred to as Kirchhoff's second law or Kirchhoff's voltage law, and it states that the algebraic sum of all the electric potential differences around any closed loop is equal to zero.

<h3>How to connect two runs in series?</h3>

Since the chairlifts are analogous to batteries, and the runs are analogous to resistors, the two runs would represent resistors that are connected in series with the lift, which represents the battery. Similarly, these three runs can also be connected in parallel by altering the positions of the runs with the battery.

For this ski resort, it ultimately implies that the total number of lifts that are used in any closed loop would be equal to zero in accordance with Kirchhoff's loop rule.

Two sources of light of wavelength 710 nm are 9 m away from a pinhole of diameter 1 mm. How far apart must the sources be for th
Zepler [3.9K]

Answer:

7.8 mm

Explanation:

Wavelength = λ = 710 nm = 710×10⁻⁹ m

Distance between light sources =  L = 9 m

Diameter of pinhole = d = 1 mm = 1×10⁻³ m

Rayleigh Criterion

D=1.22\frac{L\lambda}{d}\\\Rightarrow D=1.22\frac{9\times 710\times 10^{-9}}{1\times 10^{-3}}\\\Rightarrow D=0.0077\ m=7.8\ mm

Distance between difraction pattern is 7.8 mm.
