Answer:

The enter key is a computer innovation, which in most cases causes a command line, window form, or dialog box to operate its default function. This is typically to finish an "entry" and begin the desired process, and is usually an alternative to clicking an OK button.

What would happen if your entire kitchen was connected in series circuit? How would preparing meals and cleaning up be different

Nezavi [6.7K]

Answer:

Explanation:

When the circuit elements are connected in series, the current in each element is same but the potential difference is different.

So, as one of the circuit component breaks off or burnt, all the other components are also not working as the circuit becomes open and no current is flowing through the circuit.

500 nm light passes through a circular aperture that has a diameter d = 30.0 Î¼m. A diffraction pattern forms on a screen 350 mm

Complete Ques

Answer:

The value is $A = 0.00214 \ m^2$

Explanation:

From the question we are told that

The wavelength is $\lambda = 500 \ nm = 500 *10^{-9} \ m$

The diameter of the aperture is $d = 30 \mu m = 30*10^{-6} \ m$

The distance of the screen from the aperture is $D = 350 \ m m = 0.350 \ m$

Generally the distance from the center the the edge of the central bright fringe is magmatically reparented as

$y = \frac{m * \lambda * D}{d}$

Generally m = 1 because after the central bright fringe we have the first order fringe

$y = \frac{1 * 500 *10^{-9} * 0.350}{30*10^{-6}}$

=> $y =0.00583 \ m$

Generally the area of the central bright fringe

$A = 2 \pi * y^2$

=> $A = 2 * 3.142 * 0.00583^2$

=> $A = 0.00214 \ m^2$
