Subjects : science, literacy
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. 5/9 [T(F)-32]






2. Length of a wave






3. Current x resistance






4. Sounds above 20 -000 Hz






5. Heat Q= mass of sample x specific heat x temp change






6. Heat is carried from place to place by the bulk movement of either liquids or gasses






7. The first to do experimental studies of the laws of motion and was Imprisoned by Pope Urban VIII in 1633 for advocating the Copernican theory - also know as the heliocentric theory - that the earth was a planet revolving around the sun.






8. Force x lever arm






9. P x u x A






10. Fbottom-Ftop=mg=(density x vol) x g






11. Number density x temperature






12. The first to do experimental studies of the laws of motion and was Imprisoned by Pope Urban VIII in 1633 for advocating the Copernican theory - also know as the heliocentric theory - that the earth was a planet revolving around the sun.






13. Pascal (Pa) or pounds per square inch (psi)






14. Z+n






15. You can't get more work out than the energy you put in






16. The sum of the energy of all the molecules in the system






17. Voltage / current

19. The efficiency with which an object emits thermal radiation. Is a number between 0 and 1. A good emitter has an e close to 1.






20. Distance traveled / time






21. Are wider at the base (which lowers their center of gravity)






22. Analized brahe's data and verified the heliocentric theory. These regularities are known as Helpers Laws of Planetary motion.






23. 1 -000 kg/m^3






24. 100 -000 n/m^2






25. The change in internal energy= the heat absorbed- the work done

27. T=2p square root m/k frequency= square root k/m;/2p






28. Maximum displacement from equilibrium






29. Initial velocity= the square root of 2gh

31. Mass x velocity






32. 2p x square root L/g






33. Mass x velocity






34. Wrote Principia in 1687. Made the 3 laws of mechanics and law of gravity. He also invented calculus.






35. You cant get as much out as you put in






36. V x A= constant






37. Velocity squared / radius






38. How much torque it takes to get an object rotating






39. The efficiency with which an object emits thermal radiation. Is a number between 0 and 1. A good emitter has an e close to 1.






40. Initial velocity = acceleration x time
