d. undetermined

answer; the correct answer is technician a; ///100%good luck

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

force tends to be low and long diustance masses are high

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures
