Why do graphite and diamond look different even though they are from the same element?

Although graphite and diamond are both composed of carbon atoms, their physical properties are very different. The differences are the result of the atomic structures of the minerals. In graphite the carbon atoms are arranged in layers. As a result, graphite is soft. The great hardness of diamond is the result of the bonds that hold carbon atoms in a network structure.

Explanation:

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
