Explain an experiment of the phenomenon of rainfall​
maks197457 [2]

Unclear/incomplete question. However, I inferred you need an explanation of the phenomenon of rainfall​.

<u>Explanation</u>:

Basically, the phenomenon of rainfall​ follows a natural cycle called the water cycle. What we call <em>'rainfall'</em> occurs when water condensed (in liquid form) in the atmosphere is made to fall down on the ground as tiny droplets as a result of the forces of gravity.

<u>The water cycle makes rainfall possible:</u>

  • First, water on the earth's surface is evaporated (or is absorbed into) the atmosphere.
  • Next, it then condensed into liquid form; which later falls to the surface to the ground again. And the process continues.

A vertical beam of power intensity P (in Watts/m2 ) passes downward through a particular substance. The rate at which P decrease
Mashcka [7]

Answer:

x = 1162.5 W/m²

Explanation:

Since, the power decrease is proportional to the depth of the beam. Therefore, interpolation can be used to find the intensity of power at a depth of 1.25 m. First we calculate the slope from know points:

Slope = \frac{\Delta y}{\Delta x} \\\\Slope = \frac{(1500 - 3000)\ W/m^{2}}{(2 - 0)\ m} \\\\Slope = -750\ W/m

Now, we can find the unknown value by using this slope:

Slope = -750\ W/m = \frac{(600 - x)\ W/m^{2}}{(2 - 1.25)\ m}\\\\(-750\ W/m)(0.75\ m) = (600 - x)\ W/m^{2}\\x = 600\ W/m^{2} + 562.5\ W/m^{2}\\

<u>x = 1162.5 W/m² (Power intensity at depth of 1.25 m)</u>

If you were to create a wet mount slide with the word "lens" on the slide and placed the slide on the stage so it could be read
tigry1 [53]

A microscope is used for the purpose of magnification of an object which is usually very minute - so much so that it is not easy to be seen with the naked eye. If a mount slide contains the word <em>lens</em> which is easily readable with the naked eye and if this slide is kept under a microscope, the text will appear:

  1. From left to right that is in the same original direction as it was positioned on the slide.
  2. Highly magnified which may make it illegible to be read using the microscope.
