Good day :smile: For quite some time now, I've been thinking about what I should make my Internal Assessment for the IB course in physics on. The main objective of the IA is to find and prove a mathematical relationship between an independent and dependent variable. A very, very, simple example...

After reading about the idea of Planck Stars, I can't help but wonder how that proposition is being received by the scientific community. It seems to be a very daring concept, but creative and possible nonetheless. Thoughts?

Most likely because I don't know it.

Honestly, I don't know. The question only offers me a time, mass, and exerted force.

Sorry, it's asking for the speed of after 6 seconds.

Homework Statement As simple as the question may seem, I require some honest help. I'm particularly new to physics. The question is the following: A net force of magnitude 4.0N acts on a body of mass 3.0kg for 6.0 s. The body is initially at rest. Which of the following is the speed of the...

Wasn't the connection between electricity and magnetism first worked on by Michael Faraday?

Nope, I live in South America but I had been living in the US for about 13 years before I came to start High School here.

I can be in High School and take College courses at the same time?

Is it possible to take Calculus in High School? I'm not too sure if there is a Calculus class in my school. Another thing: should I prepare for my SAT by taking courses? There's a place in my city where they give you SAT/ACT preparatory classes and I was wondering if I should take them. A bunch...

Oh, now I understand. You've aroused a question I've had for quite some time now (as rookie as it may be): If I am theoretically traveling at the speed of light, and I were to send out a radio signal in the same direction I am moving, would its velocity add to the speed of light (2c) at which I...

There is no accurate portrayal of a wormhole, given that it's a completely hypothetical topological feature of space-time. The black hole in the film is regarded to be the closest thing to reality.

Wouldn't the reflected RADAR signal travel along with the object? Or are we assuming the object is traveling only at a percentage of the speed of light?

Thanks for the info. Is it possible to take AP courses while I'm doing IB in school? I heard you can take AP courses online.

Currently, I'm in the IB program and I've never taken any AP courses back at my old school. Since I'm planning on studying Astrophysics in College, I was wondering which one prepares me the best for things concerning subjects in math and physics? After doing some research, I found that IB...
