Thank you so much for your fast reply. Your response helped me a lot, I really appreciate it! Thanks!

Hi everyone, just a quick question.. I tried this problem using Newtons laws, not conservation of energy, and I got an answer exactly half of what the correct answer is, and I'm not sure why. Here is what I did: Net force = zero once the spring is compressed, therefore mg - kx = 0 mg = kx...

Thanks so much for your help, I'll use that method for my future calculations and make a post if I run into issues again. Really appreciate your time!

Oh I see now! I completely forgot that net force would be the sum, and so what I really calculated was Ftension + (-mg). That makes sense, thanks so much. My textbook defined g to be a positive number as well, but that lead me to another question that is perhaps semi-related to this one... If I...

Thanks for your response! I recognize that tension acts up, as that is actually how I realized my answer was incorrect (because tension is acting upwards, and upwards is positive, I should have gotten a positive value instead of my negative one). Gravity acts downwards, I agree, and that's also...

So the first thing that I did was solve for the acceleration of the elevator, given the velocities and distances given in the question. My question regarding this issue is not so much the procedure needed to solve the question, but rather the sign conventions for the values given and calculated...

Hi everyone. I was testing the pH of water that had alka seltzer placed in it. I used Bromothymol blue indicator to see the pH. The color changed to yellow, which suggests that the water was now acidic. I assume this is because of the CO2 bubbles that form which can acidify the H2O. Am I...

Hi martin. Thanks for your time and response. Regarding your reply, isn't solubility relative? When the term 'well soluble' and 'insoluble' are used, aren't they are referring to their solubility in a particular solvent? A compound may be insoluble in one substance, but greatly soluble in...

Hi everyone. I am a beginner in chemistry (introductory) so my knowledge is pretty limited when it comes to this subject. From what I have been taught, like dissolves like, meaning polar dissolves polar and non-polar dissolves non-polar. The electronegativity difference of AgCl is around 1.3...

Ah okay, so you would need to make a new function and use the letter g instead. Thanks for your help, appreciate it.

Wow, thanks for your reply! I understand now that I should have been more clear in my statement and accurately distinguish what I was referring to. On a side note... I was also thinking that there are limits to what you can express with one function notation. For example, if I were to say f(x)...

Ah okay. Thank you two so much! Really silly mistake on the third one now that I look back on it... So to clarify, if the statement is f(x) = x^2, all this means is that whatever is put into the brackets of f(x), it must follow the x^2 after it. It is okay to use variations of f(x) to explain...

Hi everyone. I'm getting slightly confused about the general function notation used. I was wondering if the name of the function were to change if there was an edit to the equation. What I mean is let's say we have the graph f(x) = x^2. If I were to vertically stretch this equation by a factor...

Ah okay, thank you very much for your reply! It makes sense that if you ingest something radioactive then you will begin to emit radiation. I guess I was overthinking the question because I thought since technically these particles are passing right through you, you are emitting radiation behind...

Hi everyone. I was thinking about the question that I stated in the title. If you are exposed to radiation, such as alpha and beta particles, you don't emit radiation. The alpha particles are merely stopped because they don't have a high penetration. The beta particles pass through your body and...
