Answer:
a) 8%
b) 0,8%
c) 0,1333%
Step-by-step explanation:
To calculate percentage uncertainty, you need to take the lowest possible value you can get (4,8s using a) as an example) and calculate the percentage of that.
(4,8/5)*100= 4%
This however is not the end, because there is the possibility of getting 5,2s as an answer. Hence the answer of 4% needs to be doubled.
Therefore, the answer for a) is (4%*2)= 8%
The same principle can be applied to figure out the answers for b) and c). In c), remember to convert 5 minutes to 300 seconds to avoid confusion between units of time.
