Find the absolute error, the upper limit and lower limit for 8 h, Least unit of measurement= 1h Absolute error =1/2 of 1 h = 0.5 h Upper limit = 8+0.5 = 8.5 h Lower limit = 8 - 0.5 = 7.5 h
To find the absolute error, upper limit, and lower limit for measuring 8 hours with a least unit of measurement of 1 hour, follow these steps:
Step 1: Determine the absolute error.
The absolute error is calculated as half of the least unit of measurement. In this case, the least unit of measurement is 1 hour. Therefore, the absolute error is 1/2 of 1 hour, which is 0.5 hours.
Step 2: Calculate the upper limit.
To find the upper limit, add the absolute error to the original measurement. The original measurement is 8 hours, and the absolute error is 0.5 hours. Thus, the upper limit is 8 + 0.5 = 8.5 hours.
Step 3: Calculate the lower limit.
To find the lower limit, subtract the absolute error from the original measurement. Using the same values, the original measurement is 8 hours, and the absolute error is 0.5 hours. Therefore, the lower limit is 8 - 0.5 = 7.5 hours.
To summarize:
- The absolute error is 0.5 hours.
- The upper limit is 8.5 hours.
- The lower limit is 7.5 hours.
To find the absolute error, upper limit, and lower limit for a measurement of 8 hours with a least unit of measurement of 1 hour, follow these steps:
1. Determine the absolute error: The absolute error is half of the least unit of measurement. In this case, the least unit is 1 hour, so the absolute error is calculated as 1/2 of 1 hour, which equals 0.5 hours.
2. Calculate the upper limit: To find the upper limit, add the absolute error to the measurement. In this case, the measurement is 8 hours, so the upper limit is calculated as 8 hours + 0.5 hours, which equals 8.5 hours.
3. Calculate the lower limit: To find the lower limit, subtract the absolute error from the measurement. Using the same example, the lower limit is calculated as 8 hours - 0.5 hours, which equals 7.5 hours.
Therefore, for a measurement of 8 hours and a least unit of measurement of 1 hour, the absolute error is 0.5 hours, the upper limit is 8.5 hours, and the lower limit is 7.5 hours.
