Describe the following physical occurrences as events, that is, in the form (x, y, z, t): (a) A postman rings a doorbell of a house precisely at noon. (b) At the same lime as the doorbell is lung, a slice of bread pops out of a toaster that is located 10 1T1 from the door in the east direction from the door. (c) Tell seconds later, an airplane arrives at the airport, which is 10 km from the door in the east direction and 2 km to the south.

Suppose that you apply +3.0 ± 0.1 A through a solenoid that has 100 ± 0 turns perunit length and a core with a magnetic permeability of 5 x10 –5 ± 0 Tm/A. What isthe value and uncertainty of the resulting magnetic field? plz hurry. tnx
