Technological progress can lead to larger quantities of output for given quantities of capital and labor. For example, Proton is a homegrown brand in result it needs to improve the machinery to run at a high speed level and increase the production. Thus, it improves the capital per effective worker. Technological progress can lead to better products. For example, Proton should enhance the improvement in automobile safety and comfort over time so that it able to compete and positioning

demand for the new Myvi increase due to buyer holding back as they wait for the new model. On the other hand, the sales of old model decrease. Myvi was still Malaysia’s best selling passenger car. From the OKS research, Malaysia Automotive Association, Proton shows the higher sales and the percentage change in revision is 14%. Analysis and the use of graph 1. According to the news report, OSK Research state that Perodua’s revised sales forecast of 195000 units was easy to hit the target due the

Beta radiation is a stream of electrons, when a beta particle is sprayed, a neutron is converted to a proton, so the mass number remains the same while the atomic number increases by one unit. And gamma rays consist high-energy photons with a relatively short wavelength (0.0005 ~ 0.1 nm). The particles emitted in radioactive decay processes have high kinetic

a +1 and oxygen is -2. In order for this to form a stable molecule the charges have to balance out each other. Atoms will react with other atoms based on their electronic structure, when mixing the two together. Atoms have both protons and electrons, protons have a +1 charge and

The mass number is the total of protons and neutrons in the atom’s nucleus. We can use this to find the number of neutrons by subtracting the number of protons, also the atomic number, from the mass. Atomic weight, also known as atomic mass, is the total mass of an atom or “the average of the mass numbers of a representative sample of atoms of an

Atom Atom – tiny but heavy, positively charged nucleus surrounded by one or more negatively charged electrons. Nucleus – contains protons, neutrons. Protons – positive Electrons – negative Neutrons – no net electric charge. All protons and all electrons have exactly the same magnitude of electric charge; but are opposite. Neutral atoms contain equal numbers of protons and electrons. Atom may lose one or more of its electrons or may gain extra electrons, in which case it will have a net positive

Chapter 5: Properties of Matter Matter is anything that has a mass and takes up space. The particle theory of matter is a theory that describes the composition and behavior. Matter can be many up of many different particles or only one. A pure substance is a type of matter that consists of only one type of particle. Then there are mixtures that are made up of at least two different types of particles. There are two different types of mixtures; mechanical mixtures and solutions. A mechanical mixture

Role of Enzymes in Processes Enzymes are proteins that carry out chemical reactions. They bind to substrates, which are basically substances that need to be broken down and changed into something else. When the enzyme and substrate bind, they form the enzyme-substrate complex. An enzyme will act

what the universe is mostly composed by what substance. By utilizing the Wilkinson Microwave Anisotropy Probe (WMAP), scientists discovered that the universe (for the first a few hundred thousand years) was an expanding gas composed primarily of protons, electrons, photons, neutrinos, and the mysterious dark matter. In the present, scientists are still bombard about dark matter and what it really is. Although, scientists do not know what dark matter is, they are certain of what it is not. Dark matter
