Thelma and Louise are driving their ‘66 Thunderbird over the edge of the grand canyon. Let’s say the wheels of a ‘66 T-bird have a diameter of 750mm. When they drive over the edge, their wheels are spinning at 700rpm and the depth of the canyon, at that point, is 1.6km. Ignoring wind resistance, how far (horizontally) from the wall of the canyon will the police find their wreckage?

Currents in dc transmission lines can be 100 a or higher. some people are concerned that the electromagnetic fields from such lines near their homes could pose health dangers. for a line that has current 150 a and a height of 8.0 m above the ground, what magnetic field does the line produce at ground level? express your answer in teslas and as a percentage of the earth’s magnetic field, which is 0.50 g. is this value cause for worry?
