| 1. | It has a hardness of 2.5-3 and a relative density of 4.3.
|
| 2. | Its wood is extremely heavy ( relative density = 1.2 ).
|
| 3. | Their mechanical properties scale with relative density according to the geometry.
|
| 4. | According to the sun article, the average relative density is 1.4.
|
| 5. | :2 is easy : just check the relative densities of helium and air.
|
| 6. | A substance with a relative density greater than 1 will sink.
|
| 7. | :I'd like an explanation of the Planck density and relative density.
|
| 8. | In modern laboratories precise measurements of relative density are made using oscillating U-tube meters.
|
| 9. | For example, an ice cube, with a relative density of about 0.91, will float.
|
| 10. | Warmer climates produce higher relative densities among populations, and habitat desirability also influences density.
