When a current is passed through a conductor wire, a magnetic field is created around the conductor. Accordingly, what does the intensity of the magnetic field occur at point A around the conductor depend on?​

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.

What do we mean by the event horizon of a black hole?
