Acube of plastic 1.2x10^-5 km on a side has a mass of 1.1 g. what is its density in g/cm^3

is the density of the cubic plastic.

Explanation:

Mass of the cubic block= m = 1.1 g

Volume of the cubic block = V

Volume of the cube =

a = side length =

1 km = 100,000 cm

Volume of cubic block =

Density of the solid block,d = ?

is the density of the cubic plastic.

i look it up online and i'll tell you

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
