2) An Atwood's machine is created by hanging a 55 kg mass by a rope that runs through a pulley and is connected to a 45 kg mass on the other side. If the masses are released, what
is the tension (in Newtons) in the rope?

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
