uncertainity = delta A / A
= 5 / 123 = 0.0407 beats/min
Percent uncertainty = delta A / A * 100 %
= [ 5 beats/min / 123 beats/min ] * 100 %
percent uncertainty = 4.07 %

An infant's pulse rate is measured to be 139 + 5 beats/min. What is the uncertainty in this measurement? uncertainty: 5 beats min What is the percent uncertainty in this measurement? percent uncertainty: 3 % Incorrect Question Credit: OpenStax College Physics
An infant's pulse rate is measured to be 141 +5 beats/min. What are the uncertainty and the percent uncertainty in this measurement? Uncertainty Number Percent Uncertainty beats Number min Tools x102
An infant’s pulse rate is measured to be 127 +/- 6 beats/min. What is the percent uncertainty in this measurement? I caculated (6/127)x100 = 4.724409449 and sapling tells me that’s incorrect.
Twin astronauts, Harry and Larry, have identical pulse rates of 76 beats/min on Earth. Harry remains on Earth, but Larry is assigned to a space voyage during which he travels at 0.84c relative to Earth. What will be Larry's pulse rate as measured by Harry on Earth? pulse rate measured by Harry: beats/min What will be Larry's pulse rate as measured by the physician in Larry's spacecraft? pulse rate measured by the physician: beats/min
Twin astronauts, Harry and Larry, have identical pulse rates of 70 beats/min on Earth. Harry remains on Earth, but Larry is assigned to a space voyage during which he travels at 0.74 c relative to Earth. What will be Larry’s pulse rate as measured by Harry on Earth? pulse rate measured by Harry: beats/min What will be Larry’s pulse rate as measured by the physician in Larry’s spacecraft? pulse rate measured by the physician:
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
24. An astronaut at rest has a heart rate of 65 beats/min. What will her heart rate be as measured by an earth observer when the astronaut's spaceship goes by the earth at a speed of 0.60 c? A. 39 beats/min B. 52 beats/min C. 108 beats/min D. 81 beats/min
Pulse rates of women are normally distributed with a mean of 77.5 beats per minute and a standard deviation of 11.6 beats per minute. Answer the following questions. What are the values of the mean and standard deviation after converting all pulse rates of women to z scores using z = (x - mu )/sigma ? mu = sigma = The original pulse rates are measure with units of "beats per minute". What are the units of the corresponding z...
You want to measure your resting pulse rate. You might count the number of beats in five seconds and multiply by 12 to get beats per minute. Consider counting the number of beats in 15 seconds and multiplying by 4 to get beats per minute. In what way will this improve the reliability of your measurement? a. This measurement will likely have a smaller variance, since you're multiplying by 4 instead of 12. b. You are less likely to make...
