The answer is C. Due to conservation of momentum.
Answer:solid
Explanation:
as there is less molecular spacing, solids have more density when compared to that of liquid and gas
Answer:
4847.94844926 kg/m³
Explanation:
= Actual density of cube = 1900 kg/m³
= Density change due to motion
v = Velocity of cube = 0.92c
c = Speed of light = 
Relativistic density is given by
The cube's density as measured by an experimenter in the laboratory is 4847.94844926 kg/m³
I think the correct answer from the choices listed above is the third option . Measuring the density of a substance <span>is most likely to produce the most precise results when trying to identify a substance since it can be compared to water and there are many data on it on books.</span>
