need soon please! please answer fully
1. (20 pts) a) (5 pts) Do magnetic field lines begin and end like electromagnetic field lines? If so, at what do they start and at what do they end? If not, what shape are they? b) (5 pts) Why is the north pole of a magnet attracted to the north pole of the...
A rail gun uses electromagnetic forces to accelerate a
projectile to very high velocities. The basic mechanism of
acceleration is relatively simple and can be illustrated in the
following example. A metal rod of mass 10.0g and electrical
resistance 0.300Ω rests on parallel horizontal rails that have
negligible electric resistance. The rails are a distance L = 5.00
cm apart....
please explain clearly why all answers are true
Problem 6: A conducting rod with negligible resistance is pulled with constant velocity along conducting rails that also have negligible resistance. A uniform magnetic fleld shows A circuit is completed at one end of the rails with a resistor d 15 cm 00 m22 B-0.8 T V 10 m/s L 10 cm...
i need help with activity 2. i
thought a would be the speed increases as the battary increases.
but for b and c i am very confused.
