A61kg astronaut (including spacesuit and equipment), is floating at rest a distance of 10 m from the spaceship when she runs out of oxygen and fuel to power her back to the spaceship. she removes her oxygen tank (3.0 kg) and flings it away from the ship at a speed of 15 m/s relative to the ship. part a: at what speed relative to the ship does she recoil toward the spaceship? my attempt: m1v1=m2v2(3kg)(15m/s) = (61kg)(v2)45 kg*m/s = (61kg)(v2)v2 = .7377 m/s

Students in an introductory physics lab are performing an experiment with a parallel-plate capacitor made of two circular aluminum plates, each 11 cm in diameter, separated by 1.0 cm. how much charge can be added to each of the plates before a spark jumps between the two plates? for such flat electrodes, assume that value of 3×106n/c of the field causes a spark.
