A shop owner wanted to sell a gold-coloured cube to Mr Lee for $2000. The shop
owner claimed that it was made of pure gold. Mr Lee wanted to investigate whether
the shop owner's claim was true. He measured the length and mass of the cube,
and found that it was 2 cm and 100 g respectively. He also found out that the density
of pure gold is 19.3 g/cm?State whether the shop owner's claim is true. Explain your answer. Is density a useful physical property for identifying an unknown substance? Explain why.

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.
