If the mass of a material is 40 grams and the volume of the material is 9 cm^3, what would the density of the material be?
solniwko [45]
Mass = m = 40 grams
Volume = V = 9 cm³
Density = d = ?

Density is defined as the ratio of mass and volume.

So,

d = m/V

Using the values, we get

d = 40/9 = 4.44 g/cm³

This means the density of material would be 4.44 g/cm³

Describe how a cold front affects weather.
gayaneshka [121]
When a cold front occurs from a cold air mass moving into a warm air mass, the warm air is forced upward. When warm air rises, it cools, and since cool air can't hold as much moisture as warm air, the water in the air gets forced out, which is what creates clouds.
