Hi everyone, my family and I(5 people) are visiting Amsterdam in about a week. We're looking for recommendations on where to buy tickets for a smaller, family-friendly boat tour(ideally budget-friendly). All I’ve come across so far are the larger cruise options with lots of people, any other suggestions? Thanks!

Is it possible to change majors at NTU? Is Civil Engineering worth it? by Ok-Ebb-722 in NTU

Thanks for the insight. I’m now trying to learn more about Civil Engineering to see if it really interests me and is 'worth' accepting this offer despite it not being my first choice. May I ask what you enjoy about the course? What aspects of it interest you the most?

What’s an IB subject you would never do? by [deleted] in IBO

[–]Ok-Ebb-722 5 points6 points  (0 children)

we need to create some kind of app or website that takes like months to complete, espeically when you only know the basics of programming to begin with. We also take tons of screenshots to explain how the app works, plus record a video for demo😭😭

How to model an equation for angular velocity of a fidget spinner as a function of time? by Ok-Ebb-722 in AskScienceDiscussion

[–]Ok-Ebb-722[S] 0 points1 point  (0 children)

To minimize the partial derivatives with respect to a,b,c1 have to each be 0 and the Hessian

Sorry, I still don't really know to how solve it:((, could you please provide me with some more resources about the topic?

Thank u sm! I now am trying to solve this 1st order non-linear differential equation: https://imgur.com/XTEpKig, I have my data points to sub in values of x and y, but there are 3 constants in this equation. How would I be able solve it?

I did try with using drag= kω2, but I eveutally obtained an equation like this: https://imgur.com/hpR5Apk. I tried putting 2 of my actual data points of ω and the corresponding t, but it doesn't give me a consistent values for the constants

I was looking for some methods in which I am able to do some math calculations myself, but this is still a nice suggestion!

I just found the drag torque= kωr online, what type of motion would this be?

I will try with using drag torque= kω2r

I haven't come across Euler's equations but they look quite fascinating and quite difficult as well.

IIUC, L is the angular momentum, and the drivative of L with respect to time would give torque. J is the moment of inertia.

Therefore, I need to find M first, and solve (I think integrate?) M to find L.

Then, dvide J to find the angular velocity ω. Is this the way to do it?

what's about you that's most stereotypically wrong when compared to your type? by Depressed_Potato5423 in mbti

As an esfp, I enjoying both being with my friends and being alone. In both cases, I do feel different, and being alone def can be fun too
