Question

if you make multiple measurements of your height, you are likely to find that the results vary by nearly half an inch in either direction due to measurement error and actual variations in height. you are slightly shorter in the evening, after gravity has compressed and reshaped your spine over the course of a day. one measurement of a mans height is 5 feet and 3 inches. part a express his height in meters, using the appropriate number of significant figures. express your answer in meters. h = m

Explanation:

Step1: Convert feet to inches

1 foot = 12 inches, so 5 feet = 5×12 = 60 inches.

Step2: Calculate total inches

The man's height is 5 feet 3 inches, so total inches = 60 + 3=63 inches.

Step3: Convert inches to meters

1 inch = 0.0254 meters, so height in meters h = 63×0.0254 = 1.6002 meters.

Step4: Determine significant figures

Since the original measurement 5 feet 3 inches has two - significant - like precision (5 and 3 are non - zero digits), we round 1.6002 to 1.6 meters.

Answer:

1.6 m
