Unformatted text preview: 50,000 volts coursing through your heart can kill you. The resistance of ones body depends on the condition, how wet or dry it is. Current=Volts/Resistance (ohms), so a wet body has less resistance, but if it is dry it has high resistance and might not kill it. 4. Explain why the happy ball was able to knock over the plank and not the sad ball in this video: http://paer.rutgers.edu/pt3/experiment.php?topicid=4&exptid=140 . The happy ball is lighter, more momentum. The sad ball is heavyer and does not bounce. Bouce creates the reaction on the board every action has an equal & opposite reaction. The bigger bounce has a bigger force on the board. Elastic collision- momentum is transferred from the happy ball to the board knocking it down. 5. A 12 volt battery provides how big of a current through a 6 Ohm resistor? Current=Volts/Resistance(Ohms), Current=12/6 Current=2...
