Homework for 11 21

As homework, I’m giving you one of the exam papers, the third one, that is named “Alternative to
practical”. This means that you are given the description and the date of an experiment and you have to do
some calculations and answer some questions. As you will see, there is a question missing (n°4) because it
is on a topic that you haven’t learnt jet.
During the exam, the time to complete this task (5 exercises) is 1 hour.
Therefore, try to answer all the questions and look at the time. How much time do you need to complete
the task?
At the end of our next lesson, you will be given the mark scheme for this paper to check your results.
