  1. 2nd/4th Quarter CRT Study Guide Answers These answers are made up versions of the ones you will see on the EQT

  2. mass Decreases Increased Decreases Increased Ones that have mass 5 inches 5 miles Nuclear forces Same ones (proton-proton) Opposite ones (proton-electron) Nuclear forces Speed speed It experienced a force Two different masses Same masses Two different velocities Two different directions Blue vehicle 0 m/s Zero 25 km/hr 12 m/s2 15 m/s2 18 m/s 80 km/hr 5000 J Zero 100 J

  3. 300 watts 490 J Equal distance opposite direction Every object over 5kg Outside force Speed, acceleration Newton’s 1st law Newton’s 3rd law Newton’s 2nd law Law of conservation of momentum Friction Inertia Potential energy Potential to kinetic back to potential At the top At the bottom Potential Kinetic is the energy of motion and potential is stored energy Friction Potential energy is changed to kinetic energy Temperature Energy increase Temperature decreases High Energy increase

  4. Low Temperature increase Energy decrease Increased decreased

  5. Increased Equal Out of the soup Solid melts Energy Particles move faster Out of the counter Out of the skillet No flow Energy flow from hand to snow From heating pad to back From back to ice pack Gas Conduction Radiation Convection Radiation Solid Contact Metal

  6. Plastic • Radiation • goes to zero • It is moving • Increase temperature • Large truck traveling 30 m/s • A bike traveling 10 m/s • Decrease temperature • Zero • Carried a distance • Harry • Bowling ball • Mechanical waves need a medium and EM do not • ANY TYPE OF EM WAVE • Frequency • Compressions are amplitudes and rarefractions are troughs • Vibrations are sound waves from the EM

  7. Radio • Ultraviolet • Gamma • Microwaves • Gamma • Compressional • Longitudinal • amplitude

  8. transverse amplitude crest longitudinal transverse transverse longitudinal transverse longitudinal compressional waves speed of light is faster higher frequency different frequencies amplitude increased light waves reflect all directions Doppler effect lower frequency refraction 100 watt bulb electromagnet electric current both have opposites attract permanent magnet is always magnetic only when current is applied increase loops in wire

  9. decrease the loops in the wire domain is aligned current produced a magnetic field around the wire mechanical energy converted to electrical energy only if it is long gains electrons friction induction like-repel & opposite- attract electrons are removed from the rod chemical reaction holding a charged particle close to a neutral object protons & electrons do not equal friction electric circuit conductors list some insulators & conductors 25 cm diameter wire 5 cm long wire

  10. short, thick, copper wire water 0.56 A 6.0 A 3 A 0.50 A ohm 30 ohms wire B thermal energy
