Answer:
![\frac{\Delta v}{v}=0.426](https://tex.z-dn.net/?f=%5Cfrac%7B%5CDelta%20v%7D%7Bv%7D%3D0.426)
Step-by-step explanation:
you have that the average sped is given by the following formula:
![v(x,t)=\frac{x}{t}](https://tex.z-dn.net/?f=v%28x%2Ct%29%3D%5Cfrac%7Bx%7D%7Bt%7D)
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):
![\frac{\Delta v}{v}=\sqrt{(\frac{0.9}{8.1})^2+(\frac{0.7}{1.7})^2}\\\\\frac{\Delta v}{v}=0.426](https://tex.z-dn.net/?f=%5Cfrac%7B%5CDelta%20v%7D%7Bv%7D%3D%5Csqrt%7B%28%5Cfrac%7B0.9%7D%7B8.1%7D%29%5E2%2B%28%5Cfrac%7B0.7%7D%7B1.7%7D%29%5E2%7D%5C%5C%5C%5C%5Cfrac%7B%5CDelta%20v%7D%7Bv%7D%3D0.426)
Hence, the relation between the uncertainty in the average velocity is 0.426

Answer:
X+-4
Step-by-step explanation:
Answer: 2/3 < (less than) 3/4
To find this answer, you could 1 use of 2 ways. You could...
- Use a calculator and divide the numerators by the denominators, to find the decimal value of the numbers. 2/3 = 0.6666... and 3/4 = 0.75. 0.666...(2/3) < 0.75 (3/4).
OR...
- Make the denominators the same and comparing the numerators to see which is greater. 2/3 * 4/4 = 8/12 and 3/4 * 3/3 = 9/12. 8 is less than 9, thus meaning 2/3 < 3/4.
I hope this helps!
