Suppose a zero-resistance rod slides to the right on two zero-res a distance of 0.330 m. The rails are connected by a 16 2 resistor, and thered b a uniform magnetic field with a magnitude of 0.850 T. (a) What emf is induced? (b) Find the speed at which the bar must be moved to produce a current of 0.145 A in the resistor. (c) What is the direction of the induced current? istance rails separated by

A)  Induced emf is  2.32 Volts

b)  The speed at which the bar must be moved to produce a current of 0.145 A in the resistor is 8.27 m/s

c)  Direction of the induced current is upward

Explanation:

A)  Induced emf is

E = IR

  =0.145  x 16

E = 2.32 Volts

b)   Since induced emf is given by

E = BLv

=>v=E/BL

     =2.32/ 0.85 x 0.33

v = 8.27 m/s

c)  Direction is upward

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
