Answer 1

submersion/ water displacement test.

Answer 2

accurate measurement of a volume of water before and after submersion of beam. the volume difference vs it's mass will give average density.

Answer 3

Not exactly, it involves integration. Section B problem 2 of the attached file

Answer 4

lol may not be your answer, but it is an extremely accurate method

Answer 5

Okay, fair enough. Can you help with the question? What is the formula required for finding the centre of mass?

Answer 6

I'm not that far in yet. physics start fall of next year.

Answer 7

okay no worries, thanks for your help
