  2. 70 40 0 Ch 36, #2: wavelength of light • 1.8 x 10-6 m • 9.5 x 10-7 m • 1.8 x 10-8 m • 9.5 x 10-6 m • Other • Didn’t finish

  3. 0 41 of 70 Ch 36, #19: resolution of telescope (in radians)? • 2.4 x 10-7 • 4.8 x 10-8 • 2.4 x 10-6 • 4.8 x 10-7 • Other • Didn’t finish

  4. 42 of 70 0 Ch 36, #20: distance between stars • 1.4 x 1011 m • 1.4 x 1010 m • 3.6 x 1010 m • 7.2 x 1010 m • Other • Didn’t finish

  5. 70 42 0 Blood flows through a coronary artery that is partially blocked by deposits along the artery wall. Through which part of the artery is the flux (volume of blood per unit time) the largest? • The narrow part • The wide part • the flux is the same in both parts

  6. 70 42 0 Blood flows through a coronary artery that is partially blocked by deposits along the artery wall. Through which part of the artery is the flow speed the largest? • The narrow part • The wide part • the speed is the same in both parts

  7. 70 37 0 Blood flows through a coronary artery that is partially blocked by deposits along the artery wall. As the platelet moves from the narrow part to the wide part, the blood experiences: • An increase in pressure • A decrease in pressure • No change in pressure

  8. 10 0 of 5 Pioneer 10 and Pioneer 11 were launched in the 1970s to explore planets in the outer solar system. They transmit radio signals back to Earth at a specific frequency. To hear these signals, scientists on Earth tune their radio dishes to: • The same frequency transmitted by Pioneer 10 • A higher frequency • A lower frequency

  9. 10 0 of 5 Aliens on a planet orbiting a nearby star send a laser signal out to space at a specific wavelength. If astronomers could detect this laser over an entire orbit and plotted wavelength versus time, they would see: • A constant wavelength • A continuously increasing wavelength • A continuously decreasing wavelength • A sine wave

  10. 10 0 of 5 You have four lasers which emit light of different colors. Which laser emits photons with the largest wavelength? • Red • Green • Blue • Yellow • Need more info

  11. 10 0 of 5 You have four lasers which emit light of different colors. Which laser emits photons with the largest energy? • Red • Green • Blue • Yellow • Need more info
