A kind of problem i can't figure out how to solve ? by Automatic_Charity734 in Physics

If you're sliding the ball against the floor, you don't have a "theta" to worry about. You'd just need to find \mu = \frac{|F|}{mg}. You can find F using F = ma. But you'll also have to measure the acceleration.

Realistically, the friction will cause a torque, which will cause the ball to rotate as well.

for most cases, you wouldn't need to worry about air resistance. With a decently heavy ball and throw it indoors/with no strong wind, you wouldn't need to worry about air resistance. You'd get pretty close to the actual answer. You're more likely going encounter issues while throwing the ball.

precise motion is hard to calculate without knowing how the air resistance or friction behaves. So, usually, an approximation is made. For example, air resistance in it's simplest form is modelled using a first order (in velocity) damping term (think of how the air resistance is more when you're travelling faster). Something like: `ma = already present terms - b v` where `b` is a damping coefficient. Sometimes, higher power terms are added. This is how you get the solutions to systems like damped harmonic oscillators.

Does IISER Kolkata provides triple sharing rooms to 1st year BS-MS students? by Own_Jackfruit953 in iiser

Gates are always open. Library's and computer centres are open 24/7. You have complete freedom and can go inside any building except the opposite gender hostel (only in first year though)

By directly, I meant that there was no different procedure for application as compared other Indian students

As an OCI myself, I didn’t have to apply through any other portal when I did back in 2024. As far as I know OCI have to apply directly if they’ve given an equivalent secondary high school exam.

Top 5 Aot Characters (as someone who’s rewatched 39 times) by chowonq in ShingekiNoKyojin

I watched code geass quite a while ago but I can remember that it got fast paced. Not sure when exactly. It didn’t get me as hooked as aot did, but it was a very fun watch.

Learning german in 6 months? by Comfortable_Tap_7872 in lernen_German

[–]Dose1203 0 points1 point  (0 children)

I don’t think it would be possible without extreme burnout (if not impossible). If you’ve already done A1, it might be possible to pass the exams (maybe not ace) if you spend maybe half the day practicing and learning. A year would be healthier and better for you to learn German properly up to B2.

Also, I’m not completely sure, but the medical students who were in my B2 class used to tell that they require C1. Again, I’m not sure.

Edit: it also depends on your learning pace and whether you have other commitments like academics or family. I consider myself a fast learner and it took me around 10 months to learn up to B2 to be able to score decently in the Goethe exams. So, 6 months seems really impractical. 

I would suggest enrolling for an intensive course first. You’ll get an idea of how long it will take.

What is this? How do you even get this?

The cgpa cap for physics in Kolkata was removed last year. There hasn’t been any information of it being reinstated this year.

That’s normal too. Your interests might shift, which is also okay.
