Awire 100 mm long is bent in a right angle such that the wire starts at the origin and goes in a straight line to x = 40.0 mm , y = 0, and then in another straight line from x = 40.0 mm , y = 0 to x = 40.0 mm , y = 60.0 mm . the wire is in an external uniform 0.300-t magnetic field in the +z direction, and the current through the wire is 5.10 a , directed from the origin into the wire. determine the magnitude of the magnetic force exerted by the external field on the wire. determine the direction of the magnetic force exerted by the external field on the wire measured clockwise from the positive x axis. the wire is removed and replaced by one that runs directly from the origin to the location x = 40.0 mm , y = 60.0 mm . if the current through this wire is also 5.10 a , what is the magnitude of the magnetic force exerted by the external field on the wire? the wire is removed and replaced by one that runs directly from the origin to the location x = 40.0 mm , y = 60.0 mm . if the current through this wire is also 5.10 a , what is the magnitude of the direction force exerted by the external field on the wire measured clockwise from the positive x axis.?

In 1995 a research group led by eric cornell and carl wiemann at the university of colorado successfully cooled rubidium atoms to the 20-200 nk temperature range. assuming (incorrectly) that the rubidium atoms behave liké particles of a classical ideal gas, calculate the rms speed of a rubidium atom at a temperature of 112.0 nk. in the experiments one particular isotope of rubidium was used, rubidium-87. the molar mass of this isotope is 86.91 q/mol. tries 0/20 submit answer
