Please don't post homework questions in a public forum and expect people to answer them for you.

At a minimum show what you have tried to come up with for an answer and people can guide you to figuring out how to solve anything that is incorrect. We'll help you understand the work, we won't do the work for you.

the best chance of getting assistance form here is to do the work, answer the questions as best you can, then post here to see if people think you are on the right track.

if you don't know how to answer those questions then you are stuffed with a capital 'F'

@ Healdam
That is NOT homework, this is Past exam question 2009, As I said I'm studying past exam paper questions. I did answer the questions but I'm not sure If I got the right answer for this questions. so That is why I asked for public help. so I can compare it with my answers.
