Hydrogen bonds or h bonds are between water molecules
A water molecule contains an oxygen atom and two hydrogen atoms which are covalently bonded to the oxygen atom.Atoms in a covalently bonded molecule are always fighting for the shared electrons, the atoms attraction to the shared electrons is called the electronegativity. Therefore, the more electronegative an atom is the more it attracts the shared electrons.The force of attraction between a partially electronegative atom and another partially positive atom is the hydrogen bond. It is the hydrogen bond that pulls water molecules together which results into a cohesive force between the water molecules.

An inorganic mineral is not composed of anything that was once alive
Explanation:
Organic minerals made from life. They mainly make up the biosphere and examples are minerals in plants and animals. Even after the death and decomposition of the living organisms, the minerals from the decomposition are considered organic. Organism matter is mainly made up of carbon and hydrogen.
Inorganic material, on the hand, are not derived from life and include substances like metal elements and inorganic salts.

Sam and Jenny ride their bikes at a constant velocity of 3 miles per hour.
Explanation:
Here we see that both of them are moving at a constant velocity which means their speed is constant and they are moving in a straight line.
Zero acceleration is implied on the bikes and the net force is BALANCED.
When forces are in balance, acceleration is zero. Velocity is constant and there is no net or unbalanced force.
Given what we know, we can confirm that the person credited with the development of interchangeable parts is Eli Whitney.
<h3>Why was this development so important?</h3>
This development greatly improved production efficiency, as know almost anyone could produce complex goods by just building specific parts.
This also greatly reduced the cost of goods and their maintenance.
Now, instead of having to replace a product when something broke, it was possible to just purchase a replacement part to fix the problem.
Therefore, given the importance of the development of interchangeable parts in terms of production and costs, it has been very well documented in history and its invention is credited to Eli Whitney.
