Question 1 A battery is used in an experiment and is connected by a 48.0 cm long gold wire with a diameter of 0.280 mm. If the battery has a voltage of 1.90 V and the resistivity of the wire is 2.4x10"8 0 m, what is the current in the wire? 0.355 A O 18.4 A O 10.2 A 83.6 A Question 2 E, R, + R, In the circuit above, c 1 = 13.8 V, R1 = 8.20 0, R2= 3.50 0, and R3 = 4.30 $. The ammeter reads a current of 0.700 A. What is the emf of the second battery? O 13.8 V O ov O 11.5 V O 14.0 V\fQuestion 1 S Glass In the figure provided, a glass sphere is suspended in air by a thread. If the sphere is negatively charged and the north pole of a bar magnet is brought near the sphere, which of the following is true? O The sphere is unaffected by the magnet. The sphere is attracted to the magnet. O The sphere is repelled by the magnet.Question 2 X X X X X X X X In the figure provided, what is the current direction in the wire? O Down O There is not enough information to determine the current direction in the wire. O UpQuestion 3 B Magnetic Field A proton is released from rest from the surface of a +7000. V electrode. It crosses the gap between the electrode, passes through a small hole in a 0 V electrode, as shown above. If the proton is deflected in the direction B, what is the direction of the magnetic field? O Out the page. O Into of the page. O Up. O Down.Question 4 Evaluate the cross product i X 13' of the two vectors above Theyr are separated by an angle of 90.0\" and have magnitudes given by: Vector A: 8.00 Vector B: 600 C (2.94e-15, into the screen) C' (48.0. out of the screen) ' (480, into the screen) (2.9549715, out of the screen] ,\\,\\,o k
