What type of bonding exists between the carbon atoms to create diamond ?

Covalent bonds.

Explanation:

Diamond is organized in a giant lattice structure with strong covalent bonds between carbon atoms. Each carbon atom forms 4 bonds. Explanation: Each carbon atom has four electrons in its outer shell, all of which form covalent bonds that are strong and hard to break.

d.) circle motion requires a force to give it a centripetal acceleration.
