- Already posted this question... still confused. The person who answered it before doesnt explain how or where they got the some figures from.Jake’s height is measured to be 67 ???ℎ??; Enrique’s height is measured as 67.2 ???ℎ??. Can we use these two measurements to determine who is taller? Use your understanding of approximate numbers to explain why or why not.Could you explain why 2.5 is the correct answer ?
- I have an homework where I was asked to get a generic 12 in/30 cm ruler and then answer the question in bold: Look at the smallest division and record what the uncertainty ▲x is of your tool. I am not sure how to ansswer this. Note: the previous question asked me to choose a unit of measurement on our tool which is the ruler and I choose inches (I hope that is a unit of measurement).Suppose your speedometer has an uncertainty of 4.5 km/h at a speed of 92 km/h. If the speedometer has the same percent uncertainty when it reads 55 km/h, what is the highest speed, in kilometers per hour, that you might be going? If the speedometer has the same percent uncertainty when it reads 55 km/h, what is the lowest speed, in kilometers per hour, that you might be going?This solution does not make sense as it does not look lik you used the correct formula for range.
- Note:- Do not provide handwritten solution. Maintain accuracy and quality in your answer. Take care of plagiarism. Answer completely. You will get up vote for sure.An ostrich runs with velocity 20 km/h for 2 hours (hrs), 12 km/h for 3 hours, and 40 km/h for another hour.Compute the total distance traveled and indicate with a graph how this quantity can be interpreted as an area.How do you estimate the error of a measurement performed with a meterstick? Why?
