An infant's pulse rate is measured to be 121 ± 3 beats per minute. what is the percent uncertainty in this measurement?

The infant's pulse rate is 121 ± 3 beats per minute, so the uncertainty of the measurement would be 3 beat per minute. To change it into percent uncertainty, you need to divide it with the measure value of the pulse rate. The calculation would be: 3 beat per minute/121 beat per minute= 2.48%

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.
