Question

(1) Determine your own height in meters, and your mass in kg. (II) To the correct number of significant figures, use the information inside the front cover of this book to deter- mine the ratio of (a) the surface area of Earth compared to the surface area of the Moon, (b) the volume of Earth compared to the volume of the Moon. 18. (II) Would a driver traveling at 15 m/s in a 35 mi/h zone be exceeding the speed limit? Why or why not? 19. (II) The age of the universe is thought to be about 14 billion years. Assuming two significant figures, write this in powers of 10 in (a) years, (b) seconds. 20. (II) The Sun, on average, is 93 million miles from Earth. How many meters is this? Express (a) using powers of 10, and (b) using a metric prefix (km).
