Best ResponseYou've already chosen the best response.01) when the number is (5.3322∗ 10^5) would the uncertainty be (1*10^9) or (0.0001)?

Best ResponseYou've already chosen the best response.02) how to calculate the absolute uncertainty when there is an exponent? For example \[(7.5899*10^{6}) *(22.62 \pm 0.01) \].

Best ResponseYou've already chosen the best response.0for example lets say u are given 10.1 you dont know if it was 10.05 to 10.15 so your uncertainty is 10.1 +/ 0.05

Best ResponseYou've already chosen the best response.0We were told in class that when the uncertainty is implicit we will assume its the last digit and it will always be 1. For example: 0.0967 the uncertainty will be 0.0001.

Best ResponseYou've already chosen the best response.0(5.3322∗ 10^5) same thing this part 5.3322 you dont know if it was 5.33215 to 5.33225 so 5.3322 +/ 0.00005

Best ResponseYou've already chosen the best response.0ok i guess that maybe fine too its like roudning up the uncertainty itself

Best ResponseYou've already chosen the best response.0+/ 0.00005 = +/ 0.0001

Best ResponseYou've already chosen the best response.0ooohhhh ok. so the uncertainty will be determined regardless of the exponent.

Best ResponseYou've already chosen the best response.0(5.33220∗ 10^5) if they want to go upto exponent

Best ResponseYou've already chosen the best response.0you have to add that 0

Best ResponseYou've already chosen the best response.0for your question 2, absolute uncertainty is that the uncertainty that is based on proportion

Best ResponseYou've already chosen the best response.0iwhen y=x^n, is the formula n* (relative uncertainty), relative uncertainty= (uncertainty/value)

Best ResponseYou've already chosen the best response.0here is a more logical approach to calculating your absolute uncertainty

Best ResponseYou've already chosen the best response.0suppose you have 10.0+/ 0.1 and 2.0+/ 0.2 you see 10.0*2.0 = 20.0 then you see the max and mix that happens with the uncertainty 10.1*2.2 = 20.2 + 2.02 = 22.22 and the min 9.9*1.8 = 180.18=17.82

Best ResponseYou've already chosen the best response.0(22.2217.82)/2 would be the uncertainty?

Best ResponseYou've already chosen the best response.0let me check how u actually find absolute uncertainties hmm
