Frictional force from the friction caused between the course pavement and the rubber tire. It wears down the tire.
Explanation:
A molten steel is in a liquid phase of matter. It has no defined volume of shape at this state. The particles inside this materials in this form is randomized by they are still attached to each other.
- On cooling, when the molten steel solidifies and sets into a solid steel beam, the particles take up a fixed position and forms a definite shape and this confers a definite volume on them.
- The randomized particles stops and forms fixed crystals about their lattice.
- This way, the beam can carry and support a fixed amount of load.
Answer:
Density is the mass of a substance per unit volume. Volume is the amount of space an object occupies.
