The volume of 5 grams of a substance is 2cm^2. Calculate the density. What might this substance be?

ρ=2.5⋅g⋅cm3

Explanation:

ρ=Mass/Volume=5⋅g2⋅cm3,

and thus typically it has the units g⋅mL−1 or g⋅cm−3.

Here, mass=5⋅g, and volume=2⋅m3.

Their quotient is the density as shown. And this could be any solid material (generally solids are denser than liquids). You will have to look up tables of densities for common materials.

c.is a substance that requires a small amount of energy per gram to raise its temperature; has strong cohesive forces between molecules.

explanation:

a colorless, transparent, odorless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms.

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
