Express the given information in Scientific notation and then arrange them in descending order of their size. Sl.No. Name of the Planet Mass (in kg) 1. Mercury 330000000000000000000000 2. Venus 4870000000000000000000000 3. Earth 5980000000000000000000000 4. Mars 642000000000000000000000 5. Jupiter 1900000000000000000000000000 6. Saturn 569000000000000000000000000 7. Uranus 86900000000000000000000000 8. Neptune 102000000000000000000000000 9. Pluto 13100000000000000000000 1. Explain the difference between (–5)2 and – 52. 2. Compare 3 × 2, 32 and 23. 3. Show that (4 – 11)2 is not equal to 42 – 112. The 1/4th of a cube unit contains about 97,700,000,000,000,000,000,000 atoms. The average size of an atom is about 0.00000003 centimetre across. Scientific notation is a shorthand way of writing such numbers. To express any number in scientific notation, write it as the product of a power of ten and a number greater than or equal to 1 but less than 10. In scientific notation, the number of atoms in a quarter is 9.77 × 1022, and the size of each atom is 3.0 × 10–8 centimetres across. 15-04-2018 1. Explain the benefit of writing numbers in scientific notation. 2. Describe how to write 2.977 × 106 in normal form. 3. Determine which measurement would be least likely to be written in scientific notation: size of bacteria, speed of a car, or number of stars in a galaxy.
