A proton moves in a circular path of the same radius as a cosmic ray electron moving at 5.5 × 106 m/s perpendicular to the Earth’s magnetic field at an altitude where the field strength is 1.0 × 10-5 T .(a) What will the speed of the proton be in m/s? sig. gif?tid=2M68-19-28-4E-A97A-18771(b) What would the radius of the path be in meters if the proton had the same speed as the electron? sig. gif?tid=2M68-19-28-4E-A97A-18771(c) What would the radius be in meters if the proton had the same kinetic energy as the electron? sig. gif?tid=2M68-19-28-4E-A97A-18771(d) What would the radius be in meters if the proton had the same momentum as the electron? sig. gif?tid=2M68-19-28-4E-A97A-18771

Complete the statement about memory improvement. ( )involves organizing and breaking down information into easier groups to expand capacity. rehearsal is the verbal repetition of information. these techniques are especially important for the improvement of ( ) memory.

Your starship, the aimless wanderer, lands on the mysterious planet mongo. as chief scientist-engineer, you make the following measurements: a 2.50-kg stone thrown upward from the ground at 14.0 m/s returns to the ground in 5.70 s ; the circumference of mongo at the equator is 2.20×10^5 km ; and there is no appreciable atmosphere on mongo. (a) the starship commander, captain confusion, asks for the following information: what is the mass of mongo? (b) if the aimless wanderer goes into a circular orbit 2.20×10^4 km above the surface of mongo, how many hours will it take the ship to complete one orbit? (c) an unmanned spacecraft is in a circular orbit around the moon, observing the lunar surface from an altitude of 44.0 km . to the dismay of scientists on earth, an electrical fault causes an on-board thruster to fire, decreasing the speed of the spacecraft by 23.0 m/s . if nothing is done to correct its orbit, with what speed (in km/h) will the spacecraft crash into the lunar surface?
