90%. If you click the round symbol with 2 rectangles in it (bottom left) it shows the right/wrong answers and then you can review the questions.

BTW They did not get Q48 wrong. It is indeed the atmospheric pressure which forces the gase in. Suction doesn't pull gas in, it's the external atmosphere that pushes it in.

This question is just for jazzie:

90% - worst on the pulley systems I reckon - I've not done that stuff for over 20 years Could not even remember first principles.

Engine, yep it is atmospheric pressure pushing air in to a lower pressure system.

86% here...
thought some of the wording was a bit sloppy, like forces in kg instead of newtons and pressure/force used interchangably (the piston one).

I think a 'centrigugal' was in there too, my old physics teacher would be livid
