Asingly charged positive ion has a mass of 3.46 × 10−26 kg. after being accelerated through a potential difference of 215 v the ion enters a magnetic field of 0.522 t in a direction perpendicular to the field. the charge on the ion is 1.602 × 10−19 c. find the radius of the ion’s path in the field. answer in units of cm.

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix.b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds.c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer.d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.
