Answer:
OB Rough sketches of each object need to be added to their notes.
Answer:
Destroys bad stereotypes.
Explanation:
Using the Internet and its possibilities, people can surf and learn about different cultures and countries. This helps them destroy bad stereotypes that they had about some countries, not knowing anything about them.
The Internet is useful for expanding people’s knowledge and help people understand foreign behavior and cultural values.
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
Mass ( Oven dried)
= 78g
Mass ( Saturated)
= 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 =
- 
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
