In 1996, NASA performed an experiment called the Tethered Satellite experiment. In this experiment a 1.97 x 104-m length of wire was let out by the space shuttle Atlantis to generate a motional emf. The shuttle had an orbital speed of 7.06 x 103 m/s, and the magnitude of the earth's magnetic field at the location of the wire was 4.81 x 10-5 T. If the wire had moved perpendicular to the earth's magnetic field, what would have been the...

In 1996, NASA performed an experiment called the Tethered Satellite experiment. In this experiment a 1.60 104-m length of wire was let out by the space shuttle Atlantis to generate a motional emf. The shuttle had an orbital speed of 7.60 103 m/s, and the magnitude of the earth's magnetic field at the location of the wire was 5.10 10-5 T. If the wire had moved perpendicular to the earth's magnetic field, what would have been the motional emf generated...

At one instant, the An astronaut is connected to her spacecraft by a 35-m-long tether cord as she and the spacecraft orbit Earth in a circular path at a speed of 6.5 x 103 m/s. voltage measured between the ends of a wire embedded in the cord is measured to be 0.42 V. Assume the long dimension of the cord is perpendicular to the vertical component of Earth's magnetic field at that instant. (a) What is the magnitude of the...

Tethers are long dangling wires that use the velocity of a spacecraft through the Earth's magnetic field to generate electrical power. Alternatively, electrical currents pushed through the tether might be used to change the spacecraft velocity for either propulsion or for braking and reentry. Several 'space tether experiments have been flown to investigate the possible use if Faraday's law for power generation and/or propulsion. Examples are the 1996 joint US/Italy effort to deploy a 20 km tether from one of...

An astronaut is connected to her spacecraft by a 27-m-long tether cord as she and the spacecraft orbit Earth in a circular path at a speed of 3.1 103 m/s. At one instant, the voltage measured between the ends of a wire embedded in the cord is measured to be 0.40 V. Assume the long dimension of the cord is perpendicular to the vertical component of Earth's magnetic field at that instant. (a) What is the magnitude of the vertical...

Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
