Question

Choose the best mathmatical model to describe the relationship of the teperature of a steel beam and its length. Assume T is for temperature, L is length and all other variables are constant.

a. L= alpha/T

b. L= alpha(T) + beta

c. L= alpha(T)^2

d. l= alpha(T)

Consider a group of students who conducted the same projectile lab you completed this week.   However, after their initial launch, they recorded a number of additional launches to check their estimate of the uncertainty in the trajectory. What is the best interpretation if after 40 launches the group

Consider a group of students who conducted the same projectile lab you completed this week.

What is the best interpretation if after 40 launches the group's carbon paper looked like the following? (The middle blue line is the prediction, the outer lines indicate the uncertainty.) There is a systematic uncertainty The uncertainty in the range was overestimated The uncertainty in the range was underestimated The uncertainty in the range was estimated accurately As in the previous question: what is the best interpretation if your carbon paper had looked like the following? The uncertainty in the range was overestimated There is a systematic error The uncertainty in the range was underestimated The uncertainty in the range was estimated exactly

Consider a group of students who conducted the same projectile lab you completed this week. However, after their initial launch, they recorded a number of additional launches to check their estimate of the uncertainty in the trajectory. What is the best interpretation if after 40 launches the groups carbon paper looked like the following? (The middle blue line is the prediction, the outer lines indicate the uncertainty.)


c. The uncertainty in the range was underestimated
