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.

Answer:
89 milliliters liquid was in the container before George added more .
Step-by-step explanation:
Let us assume that the liquid was in the container before George added more be x .
As given
George's container was partially full.
Then he added 177 milliliters more liquid to the container.
Now the container has a total of 266 milliliters of liquid.
Than the equation becomes
liquid was in the container before George added more + liquid added = Total liquid in the container
Putting all the values in the above
x + 177 = 266
x = 266 - 177
x = 89 milliliters
Therefore 89 milliliters liquid was in the container before George added more .
