<span>F= ma force is directed on the working surface so 40 = m x 2 hence
m must be 20 units needed are probably kg</span>
Okay. I'm willing to do that. But first you'll have to tell me something about the sample in question 3.
When two plates collide, it is the density that determines which plate comes out on top. <span>The more denser </span>plate<span> subducts (goes under) the less denser </span>plate<span>. Hope this answers the question. Have a nice day. Feel free to ask more questions.</span>
Answer:
Silicon (2.33 g/cm3) < Titanium (4.51 g/cm3) < Nickel (8.9 g/cm³) < Copper (8.96 g/cm³)
Explanation:
Density of copper = 8.96 g/cm³
Density of Nickel = 8.9 g/cm³
Density of Titanium = 4.51 g/cm3
density of silicon = 2.33 g/cm3
The correct order of above metals based on the increasing density is as follow
Silicon (2.33 g/cm3) < Titanium (4.51 g/cm3) < Nickel (8.9 g/cm³) < Copper (8.96 g/cm³)
Thus, copper has the highest density among all.
