Acylindrical hole is bored through a steel block, and a cylindrical piston is machined to fit into the hole. the diameter of the hole is 20.04 ± 0.01 cm, and the diameter of the piston is 19.92 ± 0.04 cm. the clearance is one-half the difference between the diameters. estimate the clearance and find the uncertainty in the estimate.

The diameter of the hole is 20.04 ± 0.01 cm

The diameter of the piston is 19.92 ± 0.04 cm.

We are given that The clearance is one-half the difference between the diameters.

So, Clearance =

                      =

Uncertainty in the estimate =  

                                              =  

So, Clearance with uncertainty is

Hence  the clearance is 0.06 and the uncertainty in the estimate. is 0.025

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
