A proton moving at 7.20 106 m/s through a magnetic field of magnitude 1.74 T experiences a magnetic force of magnitude 7.40 10-13 N. What is the angle between the proton's velocity and the field? (Enter both possible answers from smallest to largest. Enter only positive values between 0 and 360.)
IF Earth's orbit were suddenly to become much more eccentric. keeping orbital semimajor axis as is, fixed at 1 AU, but let's imagine shifting both the Earth's perihelion and aphelion points by 0.9 AU, so that at perihelion we were only 0.1 AU from th..
