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

Given a circle with an area of 25 pi in^2 <br> What is the exact circumference?

Taya2010 [7]

Answer:

31.4

Step-by-step explanation:

C = 2πr OR C = πd

But, we need to find r first.

$A = \pi r^2\\25\pi = \pi r^2\\\sqrt{25} = \sqrt{r^2} \\r=5\\\\C=2\pi r\\C=2\pi (5)\\C= 10\pi \\C= 31.4$

3x+4y=8 what equation can compare

velikii [3]

Okay First,
Start with the given equation <span>Subtract  from both sides
Rearrange the equation
Divide both sides by
Break up the fraction
Reduce
Looking at  we can see that the equation is in slope-intercept form  where the slope is  and the y-intercept is  Since  this tells us that the y-intercept is .Remember the y-intercept is the point where the graph intersects with the y-axis

What's the answer to the picture attached?

lukranit [14]

The answer is choice C. The reason why is because f(2010) = t(2010). The outputs of the f(x) and t(x) functions are the same when the input is x = 2010. In this case, the output is 740.

For each 11 mm of coloured fabric June uses to make her curtains, she also uses 1 cm of white fabric. Express the amount of whit

avanturin [10]

Answer: The amount of white fabric to coloured fabric as a ratio in its simplest form is $\frac{10}{11}$

Step-by-step explanation:

Given :

Amount of coloured fabric used by June = 11 mm = 1.1 cm (1 mm=0.1 cm)

Amount of white fabric used by June = 1 cm

To find : amount of white fabric to coloured fabric as a ratio in its simplest form

To find the ratio in simplest form , the units of both measurements should be same

Thus $\frac{\text {amount of white fabric}}{\text {amount of coloured fabric}}=\frac{1cm}{1.1cm}=\frac{10}{11}$

The amount of white fabric to coloured fabric as a ratio in its simplest form is $\frac{10}{11}$
