Physics-30 Open book review assignment Chapter 3 Show all your work 28 points After several successful trips over the ocean the passenger airship 'Hindenburg' caught re and went up in flames when mooring at Lakehurst Naval Air Station in New Jersey (USA). 13 passengers and 22 crewmen died in the disaster. Apparently, at least one of the hydrogen cells had a tear and the extremely flammable hydrogen was escaping into the ship. However, it became only a problem when the ship tried to moor and one of the theories is that the fire started just before the rst mooring cable hit the ground. Explain the possible connection between the mooring line almost hitting the ground and the ship catching fire. 2) (2 paints) Organize by conductivity: dry wood, copper, glass, Styrofoam, sweat and graphite.

If the distance between A and B were quadrupled, determine the magnitude of the resulting electric force. Explain why. 7) (7 points) Three point-charges are aligned as showr q1 and q2 is 4.0 cm and the distance between q1 -6.0 uC q2 and q3 is 3.0 cm. Determine the net force acting on charge q2 due to charges q1 and 93. 0=730 q2 93 +4.0 uC -5.0 uC Hope Christian School Physics-30Chapter 3 8) (6 points) An electron moving horizontally at 3.10 x 105 m/s K 2.00 cm V enters a 10 N/C electric field exactly halfway between two + + + + horizontal parallel plates as shown in the diagram. Determine UO the vertical displacement of the electron as it travels between 1.00 cm E the plates
