A good quiz :) However, there are a couple of mistakes:

Question 3: An object with a low centre of mass and a wide base is the most stable, not just 'a low object', as this refers more to its position.

Question 17: Generators do not 'need' AC.  Motors do, but generators don't.  Generators do make an alternating current, but they don't depend on one.

Question 18: The correct term is 'Step-up Transformer', not generator.

Other than that, just a couple of grammatical mistakes.  Overall a good quiz :)

 brilliant quiz, tests your knowledge to see how well you've studied the topic :)

does not need any correcting as josh had already pointed out what was wrong with it - which has now been corrected

Good quiz, 4 stars though the above corrections needed and it should be fewer, not 'less' waves. Well done though :)
