A 9.0 V battery is hooked up with three resistors (R1, R2, and R3) in parallel with resistances of 10.0 Ω, 25.0 Ω, and 100.0 Ω, respectively. Score a.) Draw a labeled circuit diagram for the circuit described using correct symbols. (Use computer drawing tools or hand draw, scan and copy and paste.) b.) Calculate the equivalent resistance. c.) Calculate the current passing through each resistor in the circuit. Answer: (7 points) 3. A pulley system is used to raise a 50.0kg crate 10.5 m from the loading dock to the ship. This requires a force of 130.0 N to be applied by the longshoreman. Score a.) What is the mechanical advantage of the pulley system? b.) What is the efficiency of the system if the ideal mechanical advance of the system was equal to 5.0? c.) Find both the work input and work output assuming the efficiency found in part b.

It rolls down the first drop to a height of 20.0 m (location B) then goes up the next hill where it is moving at 14.0 m/s at the top (location C). It then rolls down the second hill until it is at ground level. (location D) Score Draw a picture of the roller coaster (there should be 2 hills with the 4 marked locations). Calculate the kinetic and potential energy at each location (the top and bottom of both hills) Label your work clearly. You should have 4 locations with both KE and PE energy shown and clearly labeled. Answer: (7 points) 5. A 5.0 cm tall object is 13.0 cm to the left of a convex lens with a focal length of +7.0 cm. Score a.) Draw a ray diagram of the setup showing the location of the image. b.) Calculate the distance of the image from the lens. c.) Calculate the height of the image and identify the type of image (virtual, real, upright, inverted) Answer: Your Score © 2012, 2010 K12 Inc. All rights reserved.
