Viewers of star trek hear of an antimatter drive on the starship enterprise. one possibility for such a futuristic energy source is to store antimatter charged particles in a vacuum chamber, circulating in a magnetic field, and then extract them as needed. antimatter annihilates with normal matter, producing pure energy. ? ? what strength magnetic field in t is needed to hold antiprotons, moving at 3.5 × 10^7 m/s in a circular path 1.8 m in radius? antiprotons have the same mass as protons but the opposite (negative) charge

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?
