Answer: Pressure from when the mountain formed creates the sedimentary rock.
Explanation: it’s prob wrong but i’m taking the test rn and this is my best guess
MASS= Density times Volume
2.70*405
M= 1093.5
Answer:
Box is made up of <em>copper</em>, because density is <em>8.96 g/cm³.</em>
Explanation:
Given data:
Volume of box = 17.63 cm³
Mass of box = 158 g
Which metal box is this = ?
Solution:
First we will calculate the density of box then we will compare it with the density value of given metals.
d = m/v
d = 158 g/ 17.63 cm³
d = 8.96 g/cm³
The calculated density is similar to the given density value of copper thus box is made up of copper.
