Yes, they mean gravitational potential energy. Sorry for the confusion.

Homework Statement Let's consider two wooden logs. We burn the first one at the base of the mountain and the second one on the peak. Which one is releasing more energy? Do they release the same amount of energy? Does the potential energy affect the burning Homework Equations ## \Delta H =##...

Thank you for the explanation. Yes, you are right. It is ##0.0001 T##. Can the inverse square law be used at a larger distance from the sun? Let's say ##r \approx 50R_\odot##.

I was solving some problems from a textbook and I found this formula for the radial dependence of the sun's magnetic field, ##B(r) \approx B_{\odot} \Big(\frac{R_{\odot}}{r}\Big)^{1/2}##, where ##B_\odot \approx 0.001T## is the magnetic field strength in the photosphere. But how can this formula...

Hi! I am a first year physics student in Romania. I enjoy discussing with people about science, especially astronomy and astrophysics. So ... I am glad I've found this forum :smile:.
