Physics Stage 6 – Yr 12 Notes 9.2 Space: Context 1 – The Earth has a gravitational field that exerts a force on objects both on it and around it. Define weight as the force on an object due to a gravitational field Mass (m): • The amount of matter in a body • Constant anywhere in the universe • Scalar quantity • Measured in Kilograms (Kg) Weight (W): • The force acting on an object due to a gravitational field • Attractive force • Vector quantity

Based on quantum mechanics‚ the wave function of an atomic orbital has four quantum numbers. (a) What is the name and symbol of each of these quantum numbers? (b) Briefly explain which property of the atom each quantum number governs. (c) What are the permitted values for each quantum number? 14. Give the allowable

Objective 1. Use the analytical balance to weigh a given hydrated salt as accurate as possible in order to determine the weight of water in the salt Introduction Balances are important laboratory equipment as they are used to determine the mass of materials. Today‚ most balances used in the laboratory are analytical balances which can give readings up to four decimal places or higher. High accuracy is needed in certain experimental work such as material analysis or those involving small change

computer ------------------------------------------------- Computational chemistry From Wikipedia‚ the free encyclopedia Computational chemistry is a branch of chemistry that uses principles of computer science to assist in solving chemical problems. It uses the results of theoretical chemistry‚ incorporated into efficient computer programs‚ to calculate the structures and properties of molecules and solids. Its necessity arises from the well-known fact that apart from relatively recent results

the nucleus of the atom has a positive charge‚ and most of the mass of the atom is located in the nucleus due to the insignificance of the weight of electrons. Surrounding the nucleus is a cloud of electrons‚ which move randomly around orbitals and sub orbitals at nearly the speed of light. Other than this‚ most of the atom is empty space. The overall atom is electrically neutral‚ as the number of protons is equal to the number of electrons‚ while the nucleus carries no charge. (b) Sub atomic
