Answer:
Mass and speed.
Explanation:
From the formula k.e= ½mv². We can conclude that K.E depends on mass and speed of a body.
B false i think, i may be wrong
gold density = 19.3 g/cm³
mass = 16.5 kg = 16.5 x 10³ g
volume = 954 ml
gold density based on the experiments:
ρ = 16.5 x 10³ g / 954 ml(cm³) = 17.296 g/cm³ ( not of pure gold)
