Answer:

porosity=23.07%

x=5.974*10^9cm^3

Explanation:

One liter of oven-dry soil sampled from the Chorro Creek Ranch field requires 300 g of water to completely saturate it.

Calculate (a) its porosity, n, and (b) the volume of water required to saturate the top 20 cm of 1 hectare of the field.

-Porosity of a soil sample can be calculated in five ways but i shall use the formula below

porosity=\frac{volume of pore}{volume of total} *100%%

volume  pore volume of sample is equal to water volume used to saturate the soil

total volume=sample volume +pore volume

1L=1000cm^3

density of water=density=mass/volume

1g/cm^3=300g/volume

vol=300cm^3

total volume=300+1000

1300

porosity =(300/1300)*100%

porosity=23.07%

2. Recall that volume=area *height

1 hectare=1*10^9cm^2

the volume of soil sample=1*10^9cm^2*20cm

2*10^10cm^3

porosity=\frac{x}{x+2*10^{10} } *100%%

23%=x/(x+2*10^10)*100%

x=5.974*10^9cm^3

[4 points] Does the green LED emit light when you connect the banana plug wires across it? What does that say about the threshol
castortr0y [4]

Yes, the green LED emits light when we connect the banana plug wires across it.

This indicates that the threshold voltage is lower for the green LED light than the blue.

<u>Explanation</u>:

A banana plug is named for its resemblance to the shape of a banana. They are wider in the middle of the plug, and narrower at the top and bottom. The banana plug can be easily plugged or unplugged into the ports of speaker or receiver.

LED lights emit photons when it is applied with electrical charge. LED lights are more efficient and last longer than incandescent light bulbs. Green light is commonly provides the calming effect. It is generally used in hyper-pigmentation treatment.

How would I get this python code to run correctly? it's not working.​
Elanso [62]

Answer:

See Explanation

Explanation:

This question requires more information because you didn't state what the program is expected to do.

Reading through the program, I can assume that you want to first print all movie titles then prompt the user for a number and then print the move title in that location.

So, the correction is as follows:

Rewrite the first line of the program i.e. movie_titles = ["The grinch......."]

for each_movie_titles in movie_titles:

   print(each_movie_titles)

   

usernum = int(input("Number between 0 and 9 [inclusive]: "))

if usernum<10 and usernum>=0:

   print(movie_titles[usernum])

Line by line explanation

This iterates through the movie_titles list

for each_movie_titles in movie_titles:

This prints each movie title

   print(each_movie_titles)

This prompts the user for a number between 0 and 9    

usernum = int(input("Number between 0 and 9 [inclusive]: "))

This checks for valid range

if usernum<10 and usernum>=0:

If number is valid, this prints the movie title in that location

   print(movie_titles[usernum])
