Please help me out asap I have limited time!!! I don't need a detailed explanation just only the answers is fine! I'll make sure to leave a good review :)

If two particle tracks simultaneously appear from a common origin in the middle of a bubble chamber and there was no original track, a possible interpretation is that O a violation of the law of conservation of momentum has occurred the original particle was a high-energy photon O a bubble in the chamber split into two parts O the original particle was a neutral particle that decayed ud -> udd + uu In the given partial equation, in terms of quarks, the particle necessary to complete this equation is a(n): O antiproton O proton O neutron O antineutron A 98.4 kg football halfback carries the ball past the line of scrimmage running at 7.02 m/s [N]. He is tackled by an opposing linebacker running toward him at 4.76 m/s [S]. Their combined velocity, after the 0.285 s impact takes both of them off their feet, is 1.02 m/s [N] Based on the information from the above scenario, the mass of the linebacker is 128 kg 094.8 kg 137 kg 102 kg During the trip in the above scenario, one of Bill and Barry's companions puts a can of beef stew in the campfire to heat for supper, neglecting to open it part way to let the steam escape. Predictably, the can explodes and sends 300 g of hot stew west at 5.73 m/s. What impulse will be imparted to the 400 g of the can? 0 1.31 N's 1.72 N's 2.30 N'S 4.30 N's
