(Give your answer to 4 significant figures.) 999.0  %1000.0  % (c) Which is a more meaningful way to express the accuracy of these two numbers, significant figures or percent uncertainties?

To calculate the average velocity, a distance is measured that is 19.5 meters with an uncertainty of 0.2 meters.  Additionally, the time to travel this distance is 4.96 seconds with an uncertainty of 0.2 seconds.  What is the uncertainty of the average velocity measured, in m/s?

Determine the absolute uncertainty for the calculated value in the following scenarios. Express as (computed result) ± (absolute uncertainty) (units).   You measure the volume of a stainless steel sphere by placing it into a100 mL graduated cylinder with an uncertainty of 1 mL, with 20 mL ofwater initially. After the sphere settles, the graduated cylinder now reads22 mL. What is the volume with uncertainty?   Please use the formula I posted ! Thank you!

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 = 9.8 meters, Sx = 1.1 meters and t = 9.4 seconds and St = 1.4 seconds. What is the uncertainty in the average speed, Sv
