AP Physics Daily Problem #1
AP Physics Daily Problem #151
A metal surface, when exposed to light of 400nm wavelength, emits electrons with kinetic energy of 0.91eV. The same surface, when exposed to light of 500nm wavelength emits electrons with kinetic energy of 0.28eV. When the wavelength is increased to 600nm, no electrons are emitted.
Plot a graph of kinetic energy versus frequency here. Label the known data points:
1.0eV
0.5eV
0.0eV
5.0 6.0 7.0 8.0
Using the graph, determine the minimum frequency of light that will produce electron emissions from the metal surface.
Determine the work function of the metal.
AP Physics Daily Problem #152
21483Bi is an isotope that is capable of both alpha and beta decay.
1. 21483Bi undergoes alpha decay. Describe in detail what occurs in alpha decay and predict what the result will be.
2. 21483Bi undergoes beta decay. Describe in detail what occurs in beta decay and predict what the result will be.
3. The half-life of 21483Bi is 20 minutes. How much time has elapsed if only 1/8 of a sample of 21483Bi remains undecayed?
AP Physics Daily Problem #153
Take the attached 1998 AP Physics B Multiple Choice test.
Give yourself 90 minutes to complete the 70 questions.
Do not use a calculator or your formula sheet. They are not allowed for the Multiple Choice test!
Answer the questions by filling in the Scantron form. It will be scored when you return to class.
After you complete the timed test, go back over the test and review the problems that gave you difficulty. This is where you figure out the areas you need to review most for the AP test!
AP Physics Multiple Choice Strategies
1. Start with problem 1 and work your way through.
2. If you can easily solve the problem, do so.
3. If the problem is going to take some time to solve, put a check mark next to it and go on. Be careful to skip that answer on the answer form.
4. If the problem is a “no clue” type, put two checks next to it and go on. Again, be careful to skip the answer on the answer sheet.
5. After you get to the end, go back and work on those problems that are single-checked. Work your way through them and solve them as best you can. Don’t forget to use all the sneaky tools you can, such as dimensional analysis, information from other problems, eliminating obviously wrong responses, etc.
6. Next, tackle the “no clue” problems. By now you might have developed a clue from the other problems. If not, try dimensional analysis and eliminating silly answers, etc.
7. Finally, make sure that all answer spaces are filled in. Yes, you are penalized for incorrect answers, but that is exactly offset by the answers you get correct. Leave no answer space blank!
8. Don’t give up! You can’t afford the luxury of a negative thought! Approach every question as something new.
AP Physics Daily Problem #154
Take the attached 1998 AP Physics B Free Response test.
Give yourself 90 minutes to complete the 8 questions.
1. Be sure to look at all questions before beginning the test.
2. Do the questions you are confident about first.
3. Do the tougher questions next.
4. Save the “impossible” questions for last.
5. Never leave a question blank. Even a formula and units will get you a couple of points. If the question asks “How much energy…”, you know that the answer will be in Joules!
6. Be complete in your answers. You can get a lot of partial credit without getting the correct answer, but the reader has to be able to see what you did! The reader should be able to follow your train of thought through the entire problem.
7. If you cannot solve one part, assume an answer and continue on. Clearly state that you are assuming a value or leaving the assumed value as a variable)
You may use your calculator and formula sheet for this test.
After you complete the timed test, go back over the test and review the problems that gave you difficulty. Redo them on a separate sheet of paper.
