Question

Measurements made in the science lab must be as accurate as possible Ravi measured the length of
an iron rod as 19.34 cm Kamal's measurement was 19.25 cm and Tabish's measurement was 19.27
cm. The correct length was 19.33 cm What was the difference between the actual and measured
lengths in each student's case?​

Answer 1

Step-by-step explanation:

Ravi measured the length of an iron rod and said it was 19.34 cm. Measurement made in science lab must be as accurate as possible. Ravi measured the length of an iron rod and said it was 19.34 cm long; Kamal said 19.25 cm; and Tabish said 19.27 cm. The correct length was 19.33 cm.

Answer 2

Answer:

= -0.06 cm

Step-by-step explanation:

The actual length of the iron rod = 19.33 cm

Ravi measured = 19.34 cm

Error = measured value - actual value

       = 19.34 - 19.33 = 0.01 cm

Kamal measured = 19.25 cm

Error = 19.25 - 19.33

       = -0.08 cm

Tabish measured = 19.27 cm

Error = 19.27 - 19.33

       = -0.06 cm
