Find the uncertainty in a calculated average speed from the measurements of distance and time. Average speed depends on distance and time according to this function v(t,x) = x/t. Your measured distance and time have the following values and uncertainties x 3 meters, x =0,1 meters and t 1.8 seconds and 5t = 1.5 seconds. What is the uncertainty in the average speed, bV ? Units are not needed in your answer.

0²T მე2 ƏT B- Ət You know that T is temperature (K) and x is the x-coordinate, which is measured in meters. You also know that t is time (s) and the book uses à as the symbol for thermal conductivity, whose unit is W/m.K. What must be the units of Q and ß?
