This is a good question in that it introduces an important concept in science in that any measurement is subject to errors and it is important to understand these errors before forming hypotheses or drawing ...

Solution Summary

The inherent measurement uncertainity are examined.

QUESTION 16a:
Consider a 2470-lb automobile clocked by law-enforcement radar at a speed of 85.5 pmh (miles/hour). If the position of the car is known to be within 5.0 feet at the time of the measurement, what is the uncertainty in the velocity of the car?
QUESTION 16b:
If the speed limit is 75 mph, could the driver of th

Measurement Error And Data Representation
1. State whether or not this statement is true or false, and explain: " An experienced scientist who is using the best equipment available only needs to measure things once—provided he doesn't make a mistake. After all, if he measures the same thing twice, he will get the same resul

I have a set of calipers that can measure thickness of a few inches with an uncertainty of +/- 0.005 inches. I measure the thickness of a deck of 52 cards and get 0.590 in.
a) If I now calculate the thickness of 1 card, what is my answer (including its uncertainty)?
b) I can improve this result by measuring several decks to
