comment Can a compass be used in a submarine?
This is very interesting. Do you have any external references?

comment Acceleration reaches speed of light?
Very tempted to -1. It seems frowned upon on this site to use relativistic mass, and for good reason. It's more correct to say that its classical inertia increases as the velocity approaches $c$.

@Edward fixed technical correctness, you're right I was being sloppy with vectors/scalars.

comment Artificial planetary magnetic field
-1, there's no quantitative reasoning here. One could at least estimate a lower bound for solar panel surface area.

comment What shape would an explosion be in orbit?
Can you clarify if you're talking about milliseconds/seconds after the explosion, or hours, or days. If it's milliseconds the effects of gravity are pretty unimportant, and the primary difference between space/earth will be atmospheric pressure, the presence/lack of solid ground, and the presence/lack of oxidizer in the atmosphere.

This is not the kind of question this website favors and besides it may be more relevant on scicomp.stackexchange.com

comment Translational and Rotational Energy in Special Relativity
I don't have more time to answer this and the book I tried to look it up in lists this as a practice problem! What first comes to mind: Assuming the momentum in frame 1 zero and the kinetic energy is $E_1$, you can use the energy-momentum invariant to say $E_2^2-(P_2 c)^2=E_1^2$. Perhaps this is in the form you need?

If you're looking for practical methods there are many current methods! See: youtube.com/watch?v=FDL39J-i0yQ
