The volume of the earth is approximately 260,000,000,000 mi3. Write this number in scientific notation. 21. If light travels 10,000 km in 3.3 x 102 sec, how long will it take light to travel one meter? 22. The diameter of a human hair can measure from 1.7 x 105 meter to 1.8 x 10-4 meter. Which is the greater diameter? 23. In June 2001, the Intel Corporation announced that they could produce a silicon transistor that could switch on and off 1.5 trillion times a second. Express the speed of the transistor in scientific notation. 24. The elements in this fast transistor are 20 nanometers long. A nanometer is one-billionth of a meter. Express the length of an element in the transistor in meters using scientific notation. 25. With this transistor, computers will be able to do 1 x 102 calculations in the time it takes to blink your eye. Express the number of calculations using standard notation. 26. The length of the elements in the transistor can also be compared to the width of a human hair. The length of an element is 2 x 103 times smaller than the width of a human hair. Express 2 x 103 in standard notation.
