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

I believe the answer would be D. Your GPA is very important when it comes to scholarships and getting into good colleges.
Land and water differ into the absorption and releasing of heat, the land heats up quicker than the water, and the land also cools off quicker than the water. So when the air is hotter over the land (during the day), then the air masses are moving from the sea to the land cause they are cooler and heavier. When the air is cooler over the land (during the night), then the air masses move from the land towards the water.
Answer:
There are some countries and regions that follow unusual time zones. Many of them are in increments of a half hour, different from the usual hour difference you normally see. People traveling to and from areas of the world that use unusual time zones may become confused or have trouble discerning the local time.

Answer
Using a good circuit board PCB design and shielding techniques
Explanation
EMI is a disruptive electromagnetic energy that is released by one portion of the circuit and reaches other parts of the circuit via conducted or radiated parts.The energy can affect circuit performance or even damage brain cells when high.It is possible to reduce this effect by employing the method of shielding and ground planes to prevent interference with wireless system operations.
