A real hard science quiz

mikeyparry, totally agree. Buoyancy happens BECAUSE of the diaplacement of water (in the case of boats).

Thank you for including the answers!

8 / 10. Really 9/10 because displacement is the correct answer to question 3!

displacement is the correct answer because buoyancy of a boat is caused be the amount of water it displaces.

I want to know what 9 or 10 out of 10 means. I know that I got them all right. It didn't give me a percentage.

I am just a person interested in science. It's fascinating I think, but my degree is in English. These questions were quite straightforward and should provide little challenge to anyone with even high school science. Of course I got 10/10.

One more time I wonder about the quiz results. I got 9 out of 10 correct for score of 80%. Must be 'newer math'. When I studied 'old math' and 'new math' they both worked out to 90%.

8 / 10. Slipped up on a few!

10/10 - I remembered more than I thought I did

10/10, Not difficult, a student of science should know all these.

9 out of 10 =80 % ?
