where did the 2.5 go? Did you use it when solving for the mass?

All final answer must be up to the 3rd decimal places with the appropriate units. (a) 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 is needed to hold antiprotons, moving at 5.00 ×107 m/s in a circular path 2.00 m in radius? Antiprotons have the same mass as protons but the opposite (negative) charge. (b) Is this field strength obtainable with today’s technology or is it a futuristic possibility?

Physics solve all part please. More than 60 years ago, future Nobel laureate Sheldon Glashow predicted that if an antineutrino — the antimatter answer to the nearly massless neutrino — collided with an electron, it could produce a cascade of other particles. The Glashow resonance phenomenon is hard to detect, in large part because the antineutrino needs about 1,000 times more energy than what's produced in the most powerful colliders on Earth. Let's compare this event to an ordinary baseball with a mass of 146 g. Please use three significant figures in your calculations. 1. What is the threshold antineutrino energy for the Glashow resonance in peta electronvolts (PeV)? Answer 6.3 2. What is this threshold energy in units of joules? Answer 0.001 Joules 3. Now consider a baseball with the same kinetic energy as that of the Glashow resonance. What speed in m/s would correspond to this energy? 4. What is this rate in units of inches/second?
