In a laboratory, one of your partners determines correctly that the surface area of an object is 11.48 cm². All of the figures in this measurement are significant. Your TI-86 calculator tells you that the uncertainty is 0.02783447 cm². Find the approximate measurement and its uncertainty (A± &A). Select one: O a. (11.480±0.03) cm² O b. (11.48±0.02783) cm² O c. (11.48±0.028) cm² O d. (11.48±0.03) cm²

Roughly how many heartbeats are there in a lifetime?
In SI units, speeds are measured in meters per second (m/s). But, depending on where you live, you’re probably mole comfortable of thinking of speeds in terms of either kilometers per hour (km/h) or miles per hour (mi/h). In this problem, you will see that 1 m/s is roughly 4 km/h or 2 mi/h, which is handy to use when developing your physical Intuition. More precisely, show that (a) 1.0m/s=3.6km/h and 1.0m/s=2.2mi/h .
