The electromotive force on the free electrons in the wire is given by
E=vBl
where v is the velocity, B is the field component perpendicular to the wire and l is the length of the wire. So we get
E=15.6*40E-6*2.5m=1.56mV
Now the force that causes this to happen is given by F=q(v X B) where q is the charge on the electron which is negative. the cross product of the velocity and magnetic field points in a direction that is westward. Since the electrons are negative they are pushed to the east, leaving the west end of the wire with a positive charge .
That's called the ' NET ' force acting on the object.
Answer:
248 years
Explanation:
The last time this happened was from 1979 to 1999. It won't happen again until 2227.
The answer is the Milky Way .
D=m÷v
so density would be 57.9 ÷ 3 = 19.3 g/cm³
