1.0 ASSIGNMENT 1 1.1 Automobile Industry History The birth of the car as we know it today took several years and the works and developments of many people. It was not until 1885 that the first car rolled down the streets‚ however‚ earlier attempts at steam powered road vehicles were successful‚ giving people the idea that cars as we know them today have existed for a lot longer than they have. In the year 1769‚ a French engineer by namely Nicolas J. Cugnot invented the first automobile to

Hydrophobic substances –. III. Acids and Bases A. An acid is any substance that increases the H+ concentration of a solution. B. Acids are proton donors 1. An acid is a substance that dissociates in solution to yield hydrogen ions (H+) 2. H+ = one proton C. A base is any substance that reduces the H+ concentration of a solution D. Bases are proton acceptors E.

The evolution of the early universe was the aftermath of the big bang. The early stages of the universe evolved which lead to the creation of matter and the separation of what is now known as the four fundamental particles of the universe. The creation of matter in the early universe was aided by the four fundamental forces‚ the strong force‚ the weak force‚ the electromagnetic force and the force of gravity. The standard model includes the three of the four fundamental forces excluding gravity

The scientific definition of an atom has changed a lot throughout history. Currently‚ the atom is known as the basic unit of a chemical‚ but there was a time when that was not known among scientists. There were multiple scientists that contributed to the creation of the first Atomic Theory: Democritus‚ Antoine Lavoisier‚ Joseph Proust‚ and John Dalton. Dalton took the information that he had taken from the three scientists prior to him and put everything into one theory. The Atomic Theory is the

The basic particles of negative charge are called electrons. Each type of atom has a certain number of electrons and protons that distinguishes it from the atoms of all other elements. For example‚ the simplest atom is that of hydrogen‚ which has one proton and one electron‚ as shown in Figure 1–2(a). As another example‚ the helium atom‚ shown in Figure 1–2(b)‚ has two protons and two neutrons in the nucleus and two electrons orbiting the nucleus. Atomic Number All elements are arranged in
