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?

Who will answer first,correct and long will be marked as brainliest​

Answer 1

Answer:

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

The correct length of the iron rod = 19.33 cm

The length of the rod measured by Ravi = 19.34 cm

∴ Error made by Ravi = (19.34 – 19.33)cm = +0.01 cm

The length of the rod measured by Kamal = 19.25 cm

∴ Error made by Kamal = (19.25 – 19.33) cm = -0.08 cm

The length of the rod measured by Tabish = 19.27 cm

∴ Error made by Tabish = (19.27 – 19.33) cm = -0.06 cm.
