4 A student is vacationing at the beach and notices only a small difference between the high and low
tides. Based on the student's observations, which
Moon phase is most likely occurring?

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3

the objects have the same charge.
