  1. Review for PSC 111 Final

  2. Lab 1: Math Review • Concepts • Significant figures • 0.0061: 2 significant figures • 0.00610: 3 significant figures • 610: 2 significant figures • 610.0: 4 significant figures • Scientific notation • 1.4x10-3 = 0.0014 • 1.4x103 = 1400

  3. Lab 2: Distance and Mass • Conversion from any units of mass, time or length into another • Meters to cm • Grams to kg • Etc. • Calculating percent error • (measured value – expected value)/expected value X 100

  4. Lab 3: Density • Use a vernier • Calculate volume of definite shapes • Cylinder: • Cube: base3 • Sphere: • rectangular prism: base X width X height • Determine the density • mass / volume

  5. Lab 4: Acceleration Due to Gravity • Calculate average velocities • Calculate acceleration from velocities • Calculate speed based on initial speed and acceleration • Graph velocity vs time

  6. Lab 5: Study of Sea Water • Calculate percent of total dissolved solid (TDS) from mass of residue

  7. Lab 6: Latent Heat of Fusion • Determine the latent heat of fusion of ice by using conservation of energy • Heat lost by of water Hw=mwcwDT • Heat to raise temperature of water-ice Hwi=mwicwTf • Heat to melt ice Hi=mihiT • Hw=Hi+Hwi

  8. Lab 7: Caloric Content of Nuts • Determine the quantity of energy available in food • energy from the burning of the food is used up to warm up water: Hw=mwcwDT • Caloric content is measured in joules/gram • energy / (mass of peanut-mass residue)

  9. Lab 7: Harmonic Oscillator • Plot the period of a harmonic oscillator based on the mass hanging from the spring

  10. Lab 8: Pendulums Graph period as a function of length Determine the period of a pendulum based on a graph showing period as a function of length

  11. Lab 9 and Lab 12: Electrical Circuit • Circuits with light bulbs connected in parallel shine as much as if they were connected individually to the battery. • Circuits with light bulbs connected in series will stop shining if one of them is unscrewed. • A circuit with light bulbs connected in parallel will drain the battery faster (higher current) than with light bulbs connected in series.

  12. Lab 10: Lenses • The position where the image of an object will be formed depend on the focal length of the lens and the relative positions of the object and the lens • The magnification of a telescope depends on the ratio of the focal length of the objective and of the eyepiece M=fo/fe

  13. Lab 13: Spectroscopy • Know how to calculate the RMS • Know how to read the vernier of the spectroscope.

  14. Lab 14: the Celestial Sphere • Know how the position of the sun in the sky changes with the seasons • Highest at noon in the summer • Lowest at noon in the winter • Understand how how RA and DEC are measured on the celestial sphere. • RA: from 0h to 24h, equivalent to longitude • DEC: from -90 through 0 to +90, equivalent to latitude

  15. Lab 15: Revolution of the Moons of Jupiter • Know how to calculate the mass of a planet based on the orbital period and distance of one of its satellite. • M=a3/T2 • a needs to be in AUs and T in years
