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
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
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
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
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
