D. all of the above, although I do find it hard to believe something like flour would have a melting point, I looked up my answer to double check.
Compound consisting of a sodium ion (Na+) with a plus one charge and a fluoride ion (F-) with a minus one charge. Hope I helped!! :)
Answer:
The density in g/cm3 is 1.9333(put a line above the 3's to show it's repeating).
And no it is not gold because the density of gold in g/cm3 is 19.3.
Explanation:
Divide the mass by the volume in order to get an object's Density.
so, 23.2 divided by 1.20 mm3
=1.93333333 g/cm3
That is the density then you find out the density of gold in grams per cubic centimeter, that is 19.3 g/cm3
For example, gold will always have a density of 19.3 g/cm3; if a mineral has a density other than that, it isn't gold.
Answer:
25002m
Explanation:
V = 100 km/h
Converting to m/s, we have
V = (100 x 1000)/3600 = 27.78m/s
t = 15mins = 15 x 60 = 900secs
Displacement =?
Velocity = Displacement /Time
Displacement = Velocity x time
Displacement = 27.78 x 900
Displacement = 25002m
Since displacement and distance are measured in same unit, the distance between A and B is 25002m
