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. 100 -000 n/m^2






2. Change in velocity / time






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






4. A tendency for liquids to resist flowing.






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






6. Sounds below 30 Hz






7. Fluid flow velocity=u - fluid density=p (rho) - fluid pressure=P P +


8. Kg/m^3






9. Wavelength x frequency






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


11. Pressure x area






12. Mass x velocity






13. Sounds above 20 -000 Hz






14. Length of a wave






15. Decreases






16. Current x resistance






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






18. 2p x square root L/g






19. P + density x g h






20. Sounds below 30 Hz






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






22. ?






23. C / f






24. The total force (positive and negative) acting upon an object






25. 100 -000 n/m^2






26. If the temperature of system A is less then the temperature of system B then heat flows from B to A (hot to cold)






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






28. Heat into system - work done by system






29. 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.






30. 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.






31. 2 -700 kg/m^3






32. Work done / heat in






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






34. 5/9 [T(F)-32]






35. Mass x velocity






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






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






38. Fluid flow velocity=u - fluid density=p (rho) - fluid pressure=P P +


39. 9/5T(C)+32






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






41. The effectiveness of a material in conducting heat






42. Mass x specific heat x temperature change






43. Because nothing stops it






44. V1 x A1=v2 x A2






45. The combination of force and point of application






46. Length of a wave






47.






48. Initial velocity = acceleration x time






49. Current x voltage energy/time (joules per second)






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