Two singly ionized atoms move out of a slit at point *S* in Figure above and into a magnetic field of magnitude *0.100 T* pointing into the page. Each has a speed of *1.00 × 10^6 m/s*. The nucleus of the first atom contains one proton and has a mass of *1.67×10^-27 kg*, whereas the nucleus of the second atom contains a proton and a neutron and has a mass of *3.34×10^-27 kg*. Atoms with the same number

of protons in the nucleus but different masses are called isotopes. The two isotopes

here are hydrogen and deuterium. Find their *distance of separation* when they strike a photographic plate at *P*.

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?
