Answer:
(3) 4 cm' and 2.0 g/cm3
Explanation:
Given:
volume= V= 8 cm³
mass= m= 16 g
The density is the mass per volume of a substance, so the density of the rock is:
density= d= 16 g/8 cm³= 2 g/cm³
When we cut the rock in half, we have a half volume and a half mass:
V= 8 cm³/2= 4 cm³
m= 16 g/2= 8 g
But the density is not altered because it is an intrisic property - it does not change with the amount of subtance. Thus, the density of a half rock is:
d = m/V= 8 g/4 cm³= 2 g/cm³
D) oxygen, carbon dioxide when you breathe in, you take in oxygen and when you breath out, you release carbon dioxide.
Answer:
Forensic anthropologists.
Explanation:
Only one sickle attracted blowflies to the trace amount of blood hidden to the naked eye which resulted in the confession by the murderer.” Several decades later, forensic entomology made its way into the courthouse; today, police detectives, coroners, federal agencies, and medical examiners work closely with forensic
