AI Thread Summary
The discussion centers on two geophysics questions regarding magnetic methods and gravimetry. For magnetic methods, participants are asked to classify minerals based on magnetic susceptibility and identify iron-containing groups. The gravimetry question involves understanding how rock density is influenced by mineral composition, porosity, and pore content. Forum members emphasize the importance of demonstrating prior effort and adherence to forum rules before receiving assistance. The conversation highlights the necessity of self-research and engagement in academic discussions.

Hello, Could you tell me help with two questions, please

The question reads as follows:

1) Magnetic methods: According magnetic values
matic susceptibility minerals can be classified into three
basic groups that have their names. Bring
designation of these groups and their most basic
characteristic. Do that holding (s) groups fall Mi-
Neral containing iron? corroborate concretely

2) Gravimetry. The density of rocks and soil depends on the density of minerals, which constitute them further
porosity, and, finally, the proportion of pores filled with air and aqueous solutions. reports fol-
ing rocks in a series from lowest to highest density:

sandstone - basalt - quartz sand - Granite - amphibolite with 30% magnetite - Clay

Thank you very much for your help..

Why are you all so cruel...
 
We are not being cruel. Some day, you will be mining an asteroid by surgical emplacement of small nuclear charges. Your partner, my grand-child, will be assisting from her own spacesuit, just a metre away. You want to be sure that you know what you're doing, right?

Thread 'Confusion regarding a chemical kinetics problem'
TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
