Calculate the maximum absolute uncertainty for R if: R = 9A / B
A = 32 +/- 2 seconds
B = 11 +/- 3 seconds

1 second

0.33 seconds

9 seconds

2 seconds

6 seconds

ΔR = 9 s

Explanation:

To calculate the propagation of the uncertainty or absolute error, the variation with each parameter must be calculated and the but of the cases must be found, which is done by taking the absolute value

The given expression is      R = 2A / B

the uncertainty is                 ΔR = | | ΔA + | | ΔB

we look for the derivatives

      = 9 / B

      = 9A ( )

we substitute

     ΔR =  ΔA +  ΔB

the values ​​are

     ΔA = 2 s

     ΔB = 3 s

     ΔR =   2 +  3

     ΔR = 1.636 + 7.14

     ΔR = 8,776 s

the absolute error must be given with a significant figure

     ΔR = 9 s

answer: i think he can see forward ten seconds and move forward ten seconds but giorno can undo his actions with ger.

explanation:

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
