Midterm review 2013
- 2. Waves Draw a standing wave. Label important terms (amplitude, wavelength, node, etc)
- 3. Waves Compare longitudinal and transverse waves. Give an example of each.
- 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. Waves Define the terms and discuss how they are related. Also, what are the units of each? Wavelength Frequency Period
- 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. 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. 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. Electricity Units! Coulomb? Current? symbol? Current is measured in? Unit of energy? Units of Voltage? Measured in? Which concept connects current and voltage?
- 10. Electricity Energy transformations! Where did the energy come from to light our bulb? What type of circuit do we need?
- 11. Electricity Circuits! Compare and contrast the two types of circuits. Draw an example of each.
- 12. Electricity What equipment can be used to measure voltage and current? How should they be hooked up to the circuit?
- 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. 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. Electricity An Xbox operating at 240V draws 2A of current. Determine resistance and power.
- 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. 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. 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. 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. Electricity How do we control all of this electricity? What device(s) are used? How are these different?
- 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. 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. 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. 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. 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. Magnetism Think back to our generator Investigate… what equipment did we use? How did we use this equipment to generate electricity?
