Answer:
Explanation:
Hello!
In this case, since the density is defined as the degree of compactness of a substance, and is defined as the mass over the volume:
Given the dimensions of the bar of lead, we can compute the volume as shown below:
Thus, the density turns out:
Best regards!
Answer:
There are four lava flows which are known as, Pahoehoe lava flow, Aa lava flow, Blocky lava flow, and also Pillow lava flow. For basaltic lava flows 10-15 minutes to be thick enough to walk on, when others can take up to 7 months.
Explanation:
Answer:
position: one compound becomes 2 separate elements
synthesis: two seperate elements combining into 1 compound
single replacement: a separate element and compound switch a component
double displacement: two compounds switch elements
this is just kinda restating what red text said but this is simpler ig
Answer:
Silver and copper
Explanation:
Siliver
Electrical conductivity=62000000(s/m)
Boiling point=2162
Melting point=961.78
Phase=solid
Copper
Electrical conductivity=59000000(s/m)
Boiling point =2927
Melting point=1084.62
Phase=soild
Metals like gold, silver and copper are drawn into thin wire and are used in an electric circuit because of their high electrical conductivity
Mostly Siliver and copper are used since using gold is much expensive.
