Assume that a 100 cm3 soil core weighs 78g when oven-dried and 123 g when saturated. Calculate the total pore space and total porosity. Show all of you work.

Answers

Answer 1

To calculate the total pore space, we will find the difference between the mass of the soil when it is oven - dried and when it is saturated. Therefore, the value of the total pore space and total porosity are 45g and 45% respectively

Given that a 100 cm3 soil core weighs 78g when oven-dried and 123 g when saturated.

The given parameters are;

Volume of soil V = 100[tex]cm^{3}[/tex]

Mass ( Oven dried) [tex]M_{1}[/tex] = 78g

Mass ( Saturated) [tex]M_{2}[/tex] = 123g

In the soil formation, pore space refers to the volume of soil. And to calculate the total pore space, we will find the difference between the mass of the soil when it is oven - dried and when it is saturated. That is,

Total pore space =  [tex]M_{2}[/tex] - [tex]M_{1}[/tex]

Total pore space = 123 - 78

Total pore space = 45g

And total porosity will be the percentage of the ratio of total pore space to the given volume of the soil. That is,

Total porosity = (Total pore space / volume of the soil) x 100

Total porosity = 45/100 x 100

Total porosity = 0.45 x 100

Total porosity = 45%

Therefore, the value of the total pore space and total porosity are 45g and 45% respectively

A special promotion for its 20-ounce bottle of soda, a soft drink company printed a
message on the inside of each cap. Some of the caps said, "Please try again," while

Suppose the company is telling the truth and that every 20-ounce bottle of soda it
fills has a 1-in-6 chance of being a winner. Seven friends each buy one 20-ounce
bottle of the soda at a local convenience store. Let X = the number who win a prize.

Answers

Using the principle of binomial probability, the probability that more than 3 friends win a prize is

Recall :

P(x = x) = nCx * p^x * q^(n-x)

Given the Parameters :

Probability of success, p = 1/6 q = 1 - p = 5/6 Number of trials, n = 7x3

Hence,

P(x ≥ 3) = p(x = 3) + p(x = 4) + p(x = 5) + p(x = 6) + p(x = 7)

P(x ≥ 3) = 0.0781 + 0.0156 + 0.0019 + 0.0001 + 0.000003

P(x ≥ 3) = 0.095703

Therefore, the probability that more than 3 friends win a prize is 0.0957

When you use a match to light a candle, multiple _______ of energy occur

Answers

Answer:

transformations (missing word)

Explanation:

When you use a match to light a candle, multiple transformations of energy occur.

To light a match, mechanical energy must first be converted to thermal energy. The particles in the match release chemical energy that has been accumulated as a result of the thermal energy, which then transforms into further thermal energy and the electromagnetic energy that you see as light.

Multiple energy transformations involving mechanical, thermal, chemical, and light energy occur when you light a match.

Therefore, when you use a match to light a candle, multiple transformations of energy occur.

Hereditary spherocytosis (HS) is a disorder of red blood cells that causes the cells to be smaller and spherical instead of having the usual flattened, biconcave shape. The average diameter of normal red blood cells is 7.2μm, and the average diameter of red blood cells in a person with HS was found to be 6.7μm. The normal red blood cell has an average surface area of 136μm2 and an average volume of 91μm3.

Which of the following provides an accurate calculation of the surface area to volume ratio of an HS red blood cell, as well as a prediction of its effect on the efficient transferring of oxygen compared to a normal red blood cell?

Answers

The statement that provides an accurate calculation of the surface area to volume ratio of an HS red blood cell is The ratio is 0.89, and the cells are less efficient at transferring oxygen.

The ratio 0.89 is less than the ratio that is seen in a normal red blood cell, therefore, the cell would be less organized at moving oxygen.

Hereditary spherocytosis (HS) is often referred to as a disease that can be inherited. It is known to affects the red blood cells.

Its symptoms includes the killing of red blood cells in the spleen and their removal from the blood stream amidst others.

Answers

Answer: 16.76

Explanation: Since it says using the line tangent to the graph, you know to use point slope form, which is y-k=x(m-h). Since you are solving at x=3, y is 17 and the slope is -1.2. Plug this into your point slope form and you get y-17=-1.2(x-3). Then plug in 3.2 for your x and solve for y, should get 16.76.
