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 = 8.1 meters, Δx = 0.9 meters and t = 1.7 seconds and Δt = 1.7 seconds. What is the uncertainty in the average speed, Δv ?

Step-by-step explanation:

you have that the average sped is given by the following formula:

The uncertainty formula for a division is given by:

       (1)

Δv: uncertainty in speed

Δx: uncertainty in the distance = 0.9m

Δt: uncertainty in time = 0.7s

x: distance = 8.1m

t: time = 1.7s

You replace the values of all parameters in the equation (1):

Hence, the relation between the uncertainty in the average velocity is 0.426

0/5 is 0, 2/0 is undefined, and 0/0 is indeterminate.

step-by-step explanation:

hope my answer has you!

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
