1 How many sides does a bubble have?                                             
2   Give an example of an object which is stationary but accelerating 
3 Given a single length of resistance wire a fixed contact and a sliding contact how could you make a variable resistor whose resistance varies from zero to a maximum and then back to zero when the sliding contact contact is moved from one end of the wire to the other end?
4 In principle can you make two different volume plasticine cubes
whose sides you can measure exactly?Can you then,using all of the plasticine,mould them together into a single larger cube whose side you can measure exactly?
