  1. Physics 122: General Physics Mon, Wed 8am - 9am Tue, Thu 8am - 10 am Instructor: Svetlana Gladycheva WELCOME!

  2. target Experimental Setup: HERA accelerator in Frankfurt, Germany

  3. Ultra-cold Polarized Atomic Hydrogen Jet Target

  4. Genetically engineer proteins tagged with fluorescence, put them into cells and watch… Neuroscience, studying protein interactions responsible for communication of neurons…

  5. psi =pound/square inch The force of liquid on submerged object Is perpendicular to the object’s surface Atmospheric pressure at sea level is 105 Pa. What is it in PSI?

  6. Is pressure on these two divers different?

  7. Pascal’s principle: Change in pressure applied to an enclosed fluid is transmitted undiminished To every point of fluid in the container.

  8. Pressure measurements: • open-tube manometer • barometer Goethe barometer (water based) Mercury barometer aneroid barometer

  9. Buoyant forces and Archimedes’s principle An object completely or partially submerged in a fluid is buoyed up by a force with magnitude equal to the weight of the fluid dispersed by the object.
