Homework Help Overview

The discussion revolves around problems related to Beer's Law and colorimetry, with participants attempting to interpret equations and concepts presented in linked images. The original poster shares their attempts at calculations but expresses uncertainty about their correctness.

Discussion Character

  • Exploratory, Conceptual clarification, Problem interpretation, Assumption checking

Approaches and Questions Raised

  • Participants discuss the relevance of equations and the context of the problems, with some questioning the definitions of variables and their relationships. There are attempts to substitute values into equations, but uncertainty remains about the appropriateness of these substitutions.

Discussion Status

Some participants are seeking clarification on the context of the problems and the definitions of variables. There is an acknowledgment of the need for more information to properly address the questions posed. Guidance has been offered regarding the importance of understanding the context and the nature of the questions.

Contextual Notes

Participants note the lack of clear definitions for variables and the potential misalignment of the questions with their expected content. There is a suggestion that the problems may originate from a chemistry course, which could influence the interpretation of the questions.

Homework Equations





The Attempt at a Solution


1. I substituted x with 1.8 and got .751 then multiplied by 1000 to get 751 ohm but not sure if this process is entirely correct.
2.no idea
3.substituted 650 with y and then got 3.3 x 10^3, again not sure if right
4. no idea

I completely miss any relevant equations...

Thats the thing, Idk what even relates to this.
 
Idk is no good (see forum rules). What dyk ?
Any idea how to google Beer's law? probably yes. Least you can do is make a guess as to how this can be migrated to your exercise.

This screen dump comes from somewhere (and not from a sociology course). So there is a context.
And you must have an idea what x and y are. So be so kind as to include that knowledge under 1.
y must be some logarithm ? you substitute the 1.8 ppm for x. so the .195 is dimensionless too ? No way to get Volts per Ampere that way, right ?

And so on. I like Question 7 also: none of the answers has the dimension of concentration.

Could this be a Chemistry course ? Or am I not making friends that way ?

Sorry yea its a chemistry question.

I put it in the wrong section
 
No problem, Chemistry is physics as soon as you know what you are doing anyway. Now how about some context, etc?

Its just some basic questions about beers law and a colorimetry lab.
 
Then there is no place for resistance. Either something is completely off, or you are ignoring the context. Our bet is that there was some introduction to these questions, describing what is the experiment.
