Please help. Thanks
Imagine a world where alternating current (AC) electric power systems were not discovered at all. Using concepts of electric power systems, speculate how would a world running on direct current (DC) electric power systems look like in contrast to an AC powered world (explain these differences in aspects of the science as well as the society).

Problem 5. (4 points) Electric field induced by a changing magnetic field in a solenoid. long solenoid of radius R = 10 cm has n = 100 turns/cm and carries a time-varying current that varies sinusoidally as I- Imax cos (2rft), where Imax- 10 A is the maximum current and f-60 Hz is the frequency of the alternating current source. What is the maximum magnitude of the induced electric field inside the solenoid, a distance r- 1.3 cm from its...
