### Midterm review 2013

1. 1. Midterm Review2013
2. 2. Waves Draw a standing wave. Label important terms (amplitude, wavelength, node, etc)
3. 3. Waves Compare longitudinal and transverse waves. Give an example of each.
4. 4. Waves Consider how waves are formed in the ocean. How does a tsunami form? Using this information draw some conclusions about the relationship between important terms  ex: velocity and amplitude – how are they related? (Think: what causes the wave to grow?!)
5. 5. Waves Define the terms and discuss how they are related. Also, what are the units of each?  Wavelength  Frequency  Period
6. 6. Waves  What is the wavelength of the wave below.  What is the velocity of the wave if its frequency is 4 Hz?0.2m- 0.2m 6m
7. 7. Waves Student A is on the Huntington Beach Pier in California and notices 11x World Champion Surfer Kelly Slater in the ocean below sitting on his board waiting for a wave. As a water wave passes, Kelly bobs up and down, rising to the top of a wave crest every 10s as he waits patiently for the perfect wave.  Calculate the frequency of the passing waves.  Calculate the speed of the passing waves.
8. 8. Waves Student B shakes a slinky to create a standing wave that looks like this: 5m  What is the wavelength?  If we shake it 3x per second, what is the speed of the slinky wave?
9. 9. Electricity Units!  Coulomb?  Current?  symbol?  Current is measured in?  Unit of energy?  Units of Voltage?  Measured in?  Which concept connects current and voltage?
10. 10. Electricity Energy transformations!  Where did the energy come from to light our bulb?  What type of circuit do we need?
11. 11. Electricity Circuits!  Compare and contrast the two types of circuits. Draw an example of each.
12. 12. Electricity What equipment can be used to measure voltage and current?  How should they be hooked up to the circuit?
13. 13. Electricity What do the squiggly line symbols in our drawings represent?  Define this term.  What is it measured in?  What law helps to define this term.
14. 14. Electricity Use Ohm’s Law to determine the relationship between resistance, voltage, and current. (If one goes up, what happens to another?) What was our other mathematical equation from Chapter 6?
15. 15. Electricity An Xbox operating at 240V draws 2A of current. Determine resistance and power.
16. 16. Electricity What is the power output of a Mustang GT with a 12V battery that supplies a current of 10A to its ignition?
17. 17. Electricity A 100W light bulb runs on 200V and draws 2A of I. Running for 5 minutes (300s), how much energy is used in this time?
18. 18. Electricity Draw a parallel circuit with 3 identical light bulbs with a battery that provides 9V and a current of 3A. What is the current and voltage for each bulb?
19. 19. Electricity Draw a series circuit with 3 identical light bulbs with a battery that provides 9V and a current of 3A. What is the current and voltage for each bulb? Based on these two answers – which way are houses wired? Why?
20. 20. Electricity How do we control all of this electricity?  What device(s) are used? How are these different?
21. 21. Electricity Chapter Challenge Math!  If I use my 100W Hitachi drill for home renovation work for two hours a day, how many kW hours do I use in a day?  *1 kW = 1000W
22. 22. Electricity Review Ohm’s Law Worksheets  Online website  Chapter 6 folder  2 worksheets: “In-class” and “Homework” Review the Chapter 6 Exam  Completed as an in-class worksheet
23. 23. Magnetism Review your exams! Draw the magnetic field of a bar magnet. Draw the magnetic field around the current carrying wire indicated below: (Left Hand Rule!) Current
24. 24. Magnetism Which was does the North pole of a compass point? Why? Draw the bar magnet of Earth to substantiate your answer. Inducing Currents… “breaking out of jail” question from the exam!  Which action does NOT produce a current? Which actions do?
25. 25. Magnetism List three ways to increase the strength of a solenoid. How are a motor and a generator different?  What happened when I used two hands cranks in my demo?
26. 26. Magnetism Think back to our generator Investigate… what equipment did we use?  How did we use this equipment to generate electricity?
