S282: TMA-1

Time for the first TMA. As I flip through the pages, metaphorically as its actually delivered in PDF,my first though is it looks pretty long. Its got 5 questions, which doesn't sound that much, but it is. For instance the first question, has sub parts a), b) and c). Then part a) has sub-sub parts i) and ii), b) has i), ii) and iii) as does c). So that is 8 questions to be answered for 18 marks, in the first question alone, and a number of them are in the "explain why" category requiring more than just a number.

Question 1 (18 marks) is about black body and other radiation features such as peak wavelengths. Some calculation required, with a dose of explanation. .

Question 2 (25 marks) requires you to look at a photograph of the sun taken through a number of different filters and interpret the data. 4 sub questions, and 10 sub sub questions. Its about temperatures and emissions.

Question 3 (35 marks) you need to look at a sequence of photographs and do some work based on the images of what I think is a coronal mass ejection. This one requires calculation and a drawing to illustrate some features on the sun.

Question 4 (4 marks) is an exercise in using the planisphere to predict various starts rising and setting. You have to explain how you worked it out too.

Question 5 (18 marks) is about forward planning. TMA-2 requires one of two possible experiments to be done and this question leads you through explaining how you are going to run these experiments and when you are going to do it etc. Hopefully it is easy marks but is clearly designed to get you in the groove to run the experiment so there are no surprises.

Anyway - that's the first one down, and posted. Hope for the best!
