A16.0 m long, thin, uniform metal rod slides north at a speed of 21.0 m/s. the length of the rod maintains an east-west orientation while sliding. the vertical component of the earth's magnetic field at this location has a magnitude of 42.0 µt. what is the magnitude of the induced emf between the ends of the rod (in mv)?

14.112 mV

Explanation:

L = 16 m, v = 21 m/s, B = 42 μ T = 42 x 10^-6 T

The formula for the induced emf is given by

e = B x v x L

e = 42 x 10^-6 x 21 x 16 = 14.112 x 10^-3 V = 14.112 mV

Thus, the induce emf is 14.112 mV.

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
