• Because when the ball is higher, the vector of the force gravity creates a more perpendicular angle with the line drawn from the ball to the pivot point, this means there is greater torque, and string pivots at a greater speed, and the ball covers a…

• For b) you could find the magnetic field from each wire by themselves (ampere's law), and add them via superpositioning principle. For c) I would use F = I L x B actually I'm not sure what c) is asking for really, but if it's asking for the magn…
