Explain how solar wind energy is transferred to the polar cap ionosphere by considering a solar wind speed of 300 km/s and interplanetary magnetic field bimf of 5 nt in the -zhat direction, then: (a) obtain an estimate for the polar cap electric field ie (b) describe the ionospheric current systems in the polar cap. do you expect energy dissipation from these currents? why? or why not? (c) describe the magnetic perturbation on the ground below the polar cap from these currents

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19
