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. Number density x temperature






2. If the CG is above the edge - the object will not fall






3. 2p x square root L/g






4. Pressure x area






5. T(C) +273






6. Rod with forces applied at opposite ends in the same direction






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






8. 18600 miles/sec






9. The study of heat and its transformation into mechanical energy






10. Mass x specific heat x temperature change






11. The amount of heat that is required to raise the temperature of one g of a substance by 1 degree C.






12. The effectiveness of a material in conducting heat

14. 1 -000 kg/m^3






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






16. T^4






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






18. 1 / period (time)






19. Mass x gravity






20. 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.






21. Compiled the first detailed observational data on planetary motion (mars) - without a telescope.






22. The heat needed to raise the temperature of 1 pound of water by 1 degree F






23. Heat into system - work done by system






24. Mass x gravity






25. Believed that the natural state of objects was to be at rest






26. Fbottom=Ftop+mg where mg is the weight of the volume






27. The study of how objects behave (from the very tiny to the very big - and from the beginning of the Universe to its ultimate fate).






28. 100 -000 n/m^2






29. Shows in 1905 that newtons laws were not valid for objects moving with speeds near the speed of light.






30. Work done / heat in






31. 2 -700 kg/m^3






32. P x u x A






33. V x A= constant






34. As the speed of a moving fluid increases - the pressure within the fluid decreases


35. Believed that the natural state of objects was to be at rest






36. Maximum displacement from equilibrium






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






38. C/n






39. C/n






40. Rod with forces applied at opposite ends in opposite directions






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






42. If energy is transferred and the internal energy of system B decreases by some amount then the internal energy of system A must incrase by the same amount.






43. New theory that explained behavior at the atomic level






44. Hf






45. 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.






46. The force that brings a system back to equilibrium






47. A disturbance that propagates through a medium






48. Decreases






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