It has been proposed that extending a long conducting wire from a spacecraft (a "tether") could be used for a variety of applications, from navigation to power generation. one of the first such experiments involving this technique was an august 1992 space shuttle flight, but the tether failed and only only 250 m of the conducting wire could be let out. a 40.0 v motional emf was generated in the earth’s 5.0 × 10-5 t field, while the shuttle and tether were moving at 7.80 × 103 m/s.

Explain what happens at the saturation point when adding salt to water at room temperature.

3. a worker pushes a 30.5 kg polished stone along a polished table with a force on bonin a straight line for 5.20 s after starting from rest. there is no friction between thestone and the table. at the end of the table. the stone is hooked to a cable with a lengthof 62.0 cm to rotate it to a rough table to store until they can be picked up. the roughtable has a coefficient of static friction 0.702 with the polished stone. remember that 8= 9.80 m/s2a) what is the speed of the stone when it is hooked to the cable? b) what is the tension in the cable while the stone is rotating? (there is still nofriction)c) how much force is needed to make the stone begin sliding from rest on therough table? ius = 0.70262.0 cm30.5 kg20.5 kg6= 0
