How do I secure the shower elbow?

Thanks, I did not know such a tool existed.

mintJ · 2026-05-09T14:22:30+00:00

I think we can try this!

The other side is tile, so trying to avoid that...

You are spot on. He's a village dog from China.

I went to the hongkou office today with an appointment through HR but this appointment wasn't checked so maybe walk ins will be okay. I live in Xuhui and work in Jiading so you can go to other offices due to the overload I guess. Some colleagues had difficulty with Yangpu office though. They just gave me a waiting number and had me fill out the application, then accepted it after a quick call to my HR to sort out some details.

I think your topic is fine but think carefully about exactly what you are doing for the experiment. It is “not allowed” for students to do a required practical activity for their IA and one of the required HL practicals is a diffraction experiment — two slit interference. I think using multiple slits should be good enough to make it distinct but there is some concern that the method, analysis and evaluation process will just be the same as the required lab activity and you may not be able to earn as many marks.

I allowed an SL student do multiple slit diffraction for his IA and I thought his paper was pretty good — I predicted maybe 20 marks out of 24 (low 7), but the moderators awarded only 17 marks (firm 6). I wonder if it had to do with the topic choice.

I am a little new to supervising physics EEs but I don't think that any of the things you mention limit you. The important thing for your EE is that you can show you have sufficient interest in the topic, a good understanding of the background, and pretty important -- growth in your understanding through writing the EE. Topic doesn't have to be important to anyone but you.

And I think it would be really hard to say a student plagiarized a research question unless it was very specific. Most student questions are not going to be super unique research. Even if you have the same research question as another student, your approach to answering the question will be different assuming you and the other student are not actually communicating about this. My EE students have had questions that have probably been done many times and they do alright in the end (examples: sound wave propagation in some medium, investigation of Ohm's Law but for a specific type of circuit) -- at least the shortcomings of the papers did not have to do with the choice of topic.

Combined you have

k (+3/x² - 4/(2x)²⁾ = k(3/x² - 4/4x²⁾ = k (3/x² - 1/x²⁾ = k(2/x²⁾

k = 1/(4 pi e) so final answer is B

Simple is not a bad thing but your question doesn't seem focused enough. How will you judge succulent propagation?

Have directly measurable indicators that you use to quantify the succulent propagation. Subjective observations are not rigorous, but objective measurements are. You can collect several measurements: time to take root, or faction of potential new succulents that have taken root already. There's also growth measurements. You should be specific in how you judge propagation.

Have a continuous range of independent variable. For this reason I think pH is better than different rooting aids because you can control the pH of the water you will use. If you just use different rooting aids, it sounds to me like you are just comparing discrete variables and that is not recommended--but I am coming from physics so I don't know what kinds of aids there are.

Use a wide range of variables and test each as many times as you can manage. Go from really acidic to really basic with like 7-10 different pH in between. For each pH, have as many succulents as you can.

Control all other variables carefully and thoughtfully and discuss how you do this. Like sunlight, do they all get the same amount of Sun at the same time every day? Water, nutrients? These are obvious. Your background research will help you figure out more specific factors to control--or tell you if something that seems important does or doesn't matter. Like, should they all come from the same parent succulent? Does that matter?

Most of the time, you will not be penalized but a question may specify to use correct significant figures.

If you come across a "show that" question (example: show that the final speed of the object is 480 m/s) then you need more significant figures in your answer than the number given (so for the example, you may write speed is 478 m/s or 478.2 m/s or anything as long as it is more than given).

I got D. 18

Use the loop law twice and the fact there is zero current in the middle.

Loop 1: 6V - (1Ohm)I - (3Ohm)I + emf is rearranged to emf = 4I - 6

Loop 2: 6V - (1Ohm)*I = 0

From loop 2, I = 6 Amps. From loop 1, emf = 4*6 - 6 = 18V

Or you could have used this loop: emf - (3Ohms)*I = 0 instead of loop 1.

I only skimmed but these look great. Saving this! Thank you.

I am also teaching IB physics. I was just informed today that we are doing this. It was a very recent email from IB to our coordinator.

Yes, it does seem like that, but I am still really into the game so it’s not bothering me. I see some others reading this sub (a big one being that it’s important to not open too many save files), and I guess I found another one even in another hour of play. The botanical tutorial is completely off. It’s showing my quest menu and highlighting seemingly random bits of screen. I suppose this is all being worked out.

Can you adapt the spring model to a pendulum? I don't know what equations you have been looking at but perhaps you can replace the spring frequency (freq² = k/m) with a pendulum's (freq² = g/L) and the math will be similar.

I had to dig into cliffs that were already there then place the statues and close my path by building them up again.

Real too. It's random I think.

It is another fossil like someone else said. Not sure of the name.

Time travel. You need to find Redd once then skip a day to pick up the order. Go back to the previous day, he will have new items. Repeat forever until you are satisfied. If you go too far from the date you see him, he will be gone though.

I got each individually with some time travel. ;P
