1 WEST SPRING SECONDARY SCHOOL "THIRST FOR KNOWLEDGE" Name: WORKSHEET 6 ( ) Class: Date: Chapter 1: Indices and Standard Form Standard Form Very (arge and very small numbers are tedious to write. A system was developed to overcome this problem. It is called the Standard Form or Scientific Notation. A number in Standard Form is in the form of: A x 10 n, where 1 ^ A < 10 and n is an integer. ] -HM-. WMMMMMM IMMMMH Some examples are: 7.24x10" 1.258x x10- Converting Ordinary Form to Standard Form We live in a universe of different shapes and sizes.

4 1 The speed of light is given as 3.00 * 10 8 m/s. (a) The distance from Sun to Venus is 1.08 x 10" m. How long does light take to travel from the Sun to Venus? Express your answer in seconds. (b) If light takes 760 secondsto travel from the Sun to Mars, what is the distance from the Sun to Mars? Express your answer in standard form. 2. The base area of a rectangle tank is 3 x 10 5 cm 2 where its width and height are 4 x 10 2 cm and 5 x 10 3 cm respectively. Showing your working clearly and leaving your answers in standard form, calculate (a) its volume, (b) its length. 3. The population of China in 2007 is approximately 1.30 x The population of Thailand in 2007 is approximately 6.50x10'. (a) Express the population of Thailand as a percentage of the population of China. (b) How many more people live in China than in Thailand in 2007? Leave your answer in standard form. 4. One astronomical unit (AU) is equivalent to 150 gigametres. (a) Express 150 gigametres in metres, giving your answer in standard form. (b) Given that the speed of light to be 3 x 10 8 mis, how many seconds does light take to travel 1 AU? 5. The mass of a certain atom is 43 nanograms. (a) Write 43 nanograms in grams using standard form. (b) A container contains 4 billion atoms. Find the total mass in grams, of the atoms in the container. 6.
