$$ In this lab we learned about measuring things directly with uncertainty and measuring things indirectly and using error propagation to determine its error. Give

an example of a direct measurement and how you would measure it$.$ Give an

example of something that may be hard to measure directly but that could be

measured indirectly and how you would do it$.$ Note the examples we did in this

lab $($measuring circumference$/$ diameter to get radius or using a ruler to measure

the length of an object$)$ are not acceptable for the answer to this question, be

creative think.
