Find the uncertainty in a calculated average speed from the measurements of distance and time. Average speed depends on distance
zzz [600]

Answer:

\frac{\Delta v}{v}=0.426

Step-by-step explanation:

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

v(x,t)=\frac{x}{t}

The uncertainty formula for a division is given by:

\frac{\Delta v}{v}=\sqrt{(\frac{\Delta x}{x})^2+(\frac{\Delta t}{t})^2}        (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):

\frac{\Delta v}{v}=\sqrt{(\frac{0.9}{8.1})^2+(\frac{0.7}{1.7})^2}\\\\\frac{\Delta v}{v}=0.426

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

Use the Distributive Property to simplify (–5 – c)( –1)
bija089 [108]
With this question, the distributive property means to distribute each term in the left parentheses to each term in the right parentheses.

= (-5 - c)( -1)
multiply each term in left parentheses by each term in right parentheses

= (-5 * -1) + (-c * -1)
multiply in parentheses; negative times negative equals positive

= 5 + c


ANSWER: 5 + c

Hope this helps! :)
