Uncertainties

Question 1

Prefixes

Answer 1

Giga = x10^9
Mega = x10^6
Kilo = x10^3
Micro = x10^-6
Nano = x10^-9

Question 2

How to determine Significant figures

Answer 2

Any digit that isnt zero is significant, except for the Zeroes after the first digit.
Answer should be as many s,f as the values in the question

Question 3

Systematic uncertainty

Answer 3

Faults in apparatus or set up
Wrong experimental technique

Scales to be zeroed or else all measurements will be off by the same amount

Question 4

Random uncertainty

Answer 4

Causes one measurement to differ, comes from unpredictable changes during experiment

Question 5

Random uncertainty formula

Answer 5

(Max value - Min value)/no.of Values

Question 6

Absolute uncertainties

Answer 6

Are the exact value of tolerance of the result

Question 7

Reading uncertainties

Answer 7

Analogue : +/- half smallest division
Digital : +/- 1 in the least significant digit
