Measurement made in science lab must be as accurate as possible. Ravi measured the length of iron rod and said it was 19.34 cm long Kamal said it was 19.25cm and Tabish said it is 19.27cm . How much errors was made by each of the boys?
Answers
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
Answer:
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.Read more on Sarthaks.com - https://www.sarthaks.com/787649/measurement-made-in-science-lab-must-be-as-accurate-as-possible
