An astronaut at rest on Earth has a heartbeat rate of 61 beats/min. When the astronaut is traveling in a spaceship at 0.81c, what will this rate be as S measured by an observer also in the ship and an observer at rest on Earth? (a) an observer also in the ship (b) an observer at rest on Earth
(a) A person's "resting" heart rate is his or her normal heart rate measured while sitting still (and long after doing anything physically exerting). A nurse on Earth measures the resting heart rate of a patient as 66.0 beats/min. Imagine the patient travels aboard a spaceship moving with a constant speed of 0.89c with respect to the Earth. What would be the patient's resting heart rate (in beats/min) as measured by someone else aboard the ship? beats/min (b) Imagine an...
An astronaut whose pulse frequency remains constant at 72 beats/min is sent on a voyage. What would her pulse beat be, relative to Earth, when the ship is moving relative to Earth at (a) 0.10c and (b) 0.90c? (a) 31 beats/min (b) 31 beats/min (a) 72 beats/min (b) 72 beats/min (a) 72 beats/min (b) 31 beats/min (a) 31 beats/min (b) 72 beats/min
B. Another patient's heart rate is only 50 beats/min. Her cardiac output is 3 L/min and her EDV is 110 ml. Calculate her ESV. Show your work, indicate proper units, and circle your answer.
the heartbeat is 65 beats/min. if the heart pumps 6.7 milliL of blood per beat what volume of blood is pumped in one day? a. 6.2712 E+5 b. 3.8317 E+8 c. 1.5678 E+6 d. 5.0405E -3
