A light source shines light consisting of two wavelengths, λ1 = 540 nm (green) and λ2 = 450 nm (blue), on two slits separated by
densk [106]

Answer:

The maximun distance is  z_1 = z_2 = 0.0138m

Explanation:

    From the question we are told that

       The wavelength are  \lambda _ 1 = 540nm  (green) = 540 *10^{-9}m

                                           \lambda_2 = 450nm(blue) = 450 *10^{-9}m

        The distance of seperation of the two slit is d = 0.180mm = 0.180 *10^{-3}m

        The distance from the screen is D = 1.53m

Generally the distance of the bright fringe to the center of the screen is mathematically represented as

           z = \frac{m \lambda D}{d}

   Where m is  the order of the fringe

For the first wavelength  we have

        z_1 = \frac{m_1 (549 *10^{-9} * (1.53))}{0.180*10^{-3}}

             z_1=0.00459m_1 m

                 z_1= 4.6*10^{-3}m_1 m ----(1)

For the second  wavelength  we have              

        z_2 = m_2 \frac{450*10^{-9} * 1.53 }{0.180*10^{-3}}

        z_2 = 0.003825m_2

        z_2 = 3.825 *10^{-3} m_2 m  ----(2)

From the question we are told that the two sides coincides with one another so

            zy_1 =z_2

         4.6*10^{-3}m_1 m = 3.825 *10^{-3} m_2 m

          \frac{m_1}{m_2}  = \frac{3.825 *10^{-3}}{4.6*10^{-3}}

Hence for this equation to be solved

       m_1 = 3

and  m_2 = 4

Substituting this into the  equation

                      z_1 = z_2 = 3 * 4.6*10^{-3} = 4* 3.825*10^{-3}

      Hence z_1 = z_2 = 0.0138m

Identify the area where convection is taking place.
Softa [21]

In this area the convection is taking place inside the water which is inside the utensils.

<u>Explanation:</u>

  • Convection is the type of  heat transfer method which is usually taking place through the liquid and gases. In this convection process, the liquid acts as the medium for the heat transfer.  
  • From the given picture we can see both convection and conduction. The conduction process which occurs in the solid objects. Here the heat is directly given to the pan which is a solid conductor so the pan conducts the heat.  
  • Inside the pan there happens to be the liquid which favors the convection process and again the eggs are heated by the conduction process as the outer part of the egg is solid.

Three small but dense objects are located in the x-y plane as shown in the figure. The objects have the following masses: mA = 3
satela [25.4K]

The x and the y coordinates of the center of the mass of this system will be 43.1 m and 3.12 m respectively.

<h3>What is the center of mass?</h3>

A location is established in relation to an object or set of objects in the center of mass. It is the system's average position across all of its components.

Given data;

There are three little objects that are densely spaced out in the x-y plane.;

The value of the masses

m₁=1.41 kg

m₂=2.55 kg

m₃=3.19 kg

\rm X_{cm} =\frac{ (W_1x_1 + W_2x_2 + W_3x_3)}{(W_1 + W_2 + W_3)} \\\\\  X_{cm} ==\frac{1.41 \times 2 + 2.55 \times 6 +3.19 \times 4}{1.41+2.55+3.19} \\\\  X_{cm} =4.31 \ m

\rm Y_{cm} =\frac{ (W_1y_1 + W_2y_2 + W_3y_3)}{(W_1 + W_2 + W_3)} \\\\\  X_{cm} ==\frac{1.41 \times 2 + 2.55 \times 4 +3.19 \times 7}{1.41+2.55+3.19} \\\\  X_{cm} =3.12 \ m

Hence, the x and the y coordinates of the center of the mass of this system will be 4.31 m and 3.12 m respectively.
