(a)
To Calculate: The percentage error of the given temperature.
(a)
Answer to Problem 7P
The percentage error for the distance is
Explanation of Solution
Given:
Temperature,
Formula used:
The speed is calculated as,
Where, T is the temperature in degree Celsius.
The % error formula is,
Calculation:
According to 5-second rule, for each 5-second between seeing a lightning strike and associated Sound. The lightning is one mile distant.
Now, consider a fact that there are 5 seconds between seeing the lighting and the associated sound. So, the
The distance to the lightning is,
One mile is equal to the
Now, the percentage error of the given temperature is,
Conclusion:
The percentage error is
