Alessandro Volta's theory of contact tension considered that the emf, which drives the electric current through a circuit containing a voltaic cell, occurs at the contact between the two metals. Volta did not consider the electrolyte, which was typically brine in his experiments, to be significant.
Victoria Falls Bridge is the location for a 111 meters (364 ft) bungee jump. The Victoria Falls Bridge crosses the Zambezi River just below the Victoria Falls. The bungee jump operates off the Victoria Falls Bridge and has a 100% safety record. Over 50,000 people have bungee jumped from this location.
Optimum take off angle. The take off speed of a male elite long jumper is about 10.5 metres/second in a run through (take off angle of zero degrees) and 3.5 metres/second for a vertical jump (take off angle of 90 degrees). This decrease in speed means that the optimum angle of take off is well below 45 degrees.
