(c) What is the ratio of the magnitude of the magnetic field due to the displacement current to that due to the current at a distance r from the wire?

In the August 1992 space shuttle flight, only 250 m of the conducting tether considered could be let out. A 40.0 V motional emf was generated in the Earth’s 5.00×10−5 T field, while moving at 7.80×103 m/s . What was the angle between the shuttle’s velocity and the Earth’s field, assuming the conductor was perpendicular to the field?

0₁ 0₂ A hemispherical grounding electrode of radius a = 1m is buried into the earth as shown in the cross-sectional figure above, but it happens to be right at the boundary of two types of soil with different conductivities. The conductivities are given by ₁ = 2 × 10-³ S/m and 02 = 8 x 10-³ S/m. The intensity of the current flowing into the electrode is I = 50 A. Answer the following questions, remembering to state and justify any assumptions you are making in your derivation: 1. What is the grounding resistance of the (entirety of the) earth in this configuration? Assume the soil extends to infinity in the region below the air/soil interface. 2. How much power is lost due to Joule/Ohmic heating in each of the two regions of the two types of soil?
