The graph shows the results of an experiment in which the distance travelled by an object was measured against the time travelled for.

using the information above, answer these 3 questions.

a) comment on the shape of the graph drawn for the plotted results.

b) is it possible to decide whether the plotted results are valid? provide a reason for your answer.

c) describe the motion of the object used to do this experiment based on the plotted points. justify your answer.

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume

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
