Across 4. The process which occurs when the vapor pressure of a liquid is equivalent to the pressure exerted on the liquid by the surroundings. 6. The work done by this type of force on an object in moving it between two points is path-independent. 12. The reflection of sound. 13. The type of flow of electric charge in which electrical power is typically delivered to businesses and residences. (2 Words) 14. A temperature-measuring device which measures the electromotive force produced by junctions formed between two dissimilar conductors. 15. The phenomenon where certain materials become electrically charged after coming into frictive contact with another material. (2 Words) 16. Radiation with sufficiently high energy to liberate electrons from atoms or molecules. (2 Words) 20. This process is used to decompose a function into its constituent trigonometric functions. (2 Words) 21. The flow of a physical property in space, sometimes with time variation. 22. Absolute pressure minus tmospheric pressure. (2 Words) 24. The type of electromagnetic radiation has been known to cause sunburn due to over-exposure. (2 Words) 26. A highly sensitive instrument used to detect an electric current. 28. This term can be used to describe either the production of an electromotive force across a conductor when it is exposed to a varying magnetic field. 29. These are circular electric currents induced within conductors by a changing magnetic field in the conductor. (2 Words)

Down 1. This set of equations describe the behaviour of light when moving between media of differing refractive indices. (2 Words) 2. Total internal reflection occurs when the angle of incidence is greater than the _______. (2 Words) 3. The mechanical advantage of a lever can be determined by considering the ________ about the fulcrum. 4. His principle states that an increase in the pressure of a fluid is always accompanied by a decrease in its speed and vice versa. 5. The reaction force perpendicular to the surface of contact. (2 Words) 7. The SI unit of the physical quantity that measures an object's resistance to being accelerated by a force. 8. An electrical device that transfers energy from one circuit to another, usually with a change in voltage. 9. The topic in applied science and engineering that deals with the mechanical properties of liquids. 10. The observation that many metals emit electrons when light shines upon them. (2 Words) 11. The influence that moves charge from a lower to higher potential, measured in joules per coulomb. (2 Words) 17. The unidirectional flow of electric charge. (2 Words) 18. A property that quantifies how strongly a given material opposes the flow of electric current. 19. The property of waves that can oscillate in multiple orientations. 23. This phenomenon has been known to result in the structural failure of components due to the tendency of a system to oscillate with greater amplitude at some frequencies. 25. An electrically neutral medium of ions and electrons that interact strongly with electric and magnetic fields. 27. A universal and fundamental quantity that describes a system's ability to do work and exists in many forms.
