Spaceship near black hole?
Hey everyone, I can't get any further with the following task
Physics sucks?
What should one do here answer otherwise I'll cry
Help physics task movement?
Hello, Our physics teacher gave us a task and I'm absolutely stuck… "Alice and Bob both love swimming. Since they live at opposite ends of a lake, they arrange to meet for training: Alice swims the shortest route to Bob's home, takes a 10-minute break there, and then swims back home. At the same time…
Switching process?
Hey everyone, can someone help me, especially with the C? I'm totally unsure what to calculate (I have a rough idea of the other problem areas, but I'm not entirely sure about them either). physics
Dynamo physics?
Hey, can someone tell me if my solution is correct? And I'm not sure if the area is correct?
RCL circuit, how do I transform the following expressions?
Hey, I don't really understand how you came up with the expression highlighted in red. They're probably basic Maghe rules, but I'm confused. And here I'm having a really hard time transforming it into real and imaginary parts. It's been a constant stumbling block for some reason… 🙁
Alternating voltage?
Hey, I have another question about the following problem. Does what I've calculated make any sense? If not, what would your approach be? I know that you can calculate the phase shift by dividing the arctan of the imaginary part by the real part, but I don't understand how to get the real part and…
Double slit?
Hi, I'm not sure how to solve this problem. You can see my approach below, but I'm not sure if it's correct in any way. For me, L is the distance to the screen, and dk is the distance between two adjacent maxima.
Calculate phase shift, how do you get the real and imaginary parts?
Hey, during the semester we had to calculate the phase shift between the output and input voltages. I know that you can calculate the phase shift by dividing the arctan of the imaginary part by the real part of the resistance. But I'm wondering how I know what my Im and Re parts are. The…
Magnetic coil with core?
Hey everyone, I'm sorry that I have so many tasks at the moment, but it's exam time again 🙁 I've found a way to calculate the following problem, but I'm extremely unsure, especially about b. And regarding d: since the susceptibility is less than 1, bismuth should be diamagnetic, right?
Band leader?
Hey, can someone help me with the following task? I have some ideas, but can I actually implement them?
Speaker in AC circuit?
Hey everyone, I have another question about electrical engineering Here you can see my approach, but I'm really confused. I still don't fully understand what I'm actually trying to achieve. I'd be incredibly grateful for any help!
