Answer:
Temperature affects Seismic Wave speed.
Explanation:
Both temperature and pressure affect the speed of Seismic waves. The Speed of Seismic waves increases uniformly as pressure increases, meaning that as depth increases, pressure also increases which causes Seismic Wave speeds to increase as well. This can be calculated and the data can be gathered. Temperature on the other hand decreases the speed of Seismic Waves, therefore we can calculate the difference of speed between what the Seismic Wave should be at a certain pressure with the actual speed gathered. This difference in speed will allow us to determine the actual temperature at that level.
Actually mass and weight are two different things but most people did not understand the difference between them. And they are used synonymously on the earth. Mass is the measure of the amount of matter and weight is the measure of how the force of gravity acts on the mass that is Weight = mass x force of gravity. And they are also directly proportional to each other that is also the reason both terms are used synonymously.
Answer:
<u />
- <u>There are 0.041 g of NH₃ in the same number of molecules as in 0.35 g of SF₆.</u>
<u />
Explanation:
Using the molar mass of the chemical formula SF₆ you can find the number of moles of molecules in 0.35 g of such substance. Then, using the molar mass of NH₃, you can find mass in grams corresponding to the same number of molecules.
<u>1. Find the molar mass of SF₆:</u>
Atom atomic mass number of atoms total mass in 1 mole
S 32.065 g/mol 1 32.065 g
F 18.998 g/mol 6 6 × 18.998 = 113.988 g
=====================
molar mass of SF₆ = 146.053 g/mol
<u>2. Find the number of moles in 0.35 g of SF₆:</u>
- number of moles = mass in grams / molar mass
- number of moles = 0.35 g / 146.053 g / mol = 0.0024 mol
<u>3. Find the molar mass of NH₃:</u>
Atom atomic mass number of atoms total mass 1 mole
N 14.007 g/mol 1 14.007 g
H 1.008 g/mol 3 3 × 1.008 g = 113.988 g
=====================
molar mass of NH₃ = 17.031 g/mol
<u />
<u>4. Find the mass in 0.0024 mol of NH₃:</u>
- mass in grams = number of moles × molar mass
- mass = 0.0024 mol × 17.031 g/mol ≈ 0.041 grams
<u>5. Conclusion: </u>
There are 0.041 g of NH₃ in the same number of molecules as in 0.35 g of SF₆.
Answer: the way root cells reproduce to increase root length
Explanation:
Rudolf Ludwig Carl Virchowas known as the founder of social medicine and also the father of modern pathology.
Virchow posited that all cells are gotten from already existing cells and he used this in his work towards cellular pathology, as it was made clear that diseases takes place at the cellular level. He posited that the cells that are malfunctioning cause diseases.
Based on the above analysis, the image that Tumu would most likely use in his assignment to feature Rudolf Virchow is the way root cells reproduce to increase root length.
