- Why was m converted to cm?One of the main speed tests in athletics is the 400 meters dash. At the 1999 Seville World Championship, athlete Michael Johnson won that event, with 43.18 seconds. This time, second, written in scientific notation is: a. 0.4318 x 102 b. 4.318 x 101 c. 431.8 x 10-1 d. 43.18 x 100 e. 4,318 x 10-2I know the answer is 0.22 m/s. I just don't understand how to get it.
- How far has a car traveled in 4 hours if it is constantly moving at 60 miles / hour? a.60 miles. b.4 miles. c. 64 miles. d. 240 miles.There are two parts to this question. I need to know the km/s and the hr. Thank you!Assume your hair grows at a rate of 1/44th of an inch per day. How fast is that in nm/s (nanometers per second)? Given that a typical atom is on the order of 1 x 10^(-10) m in diameter (see Table 1.3 on page 18 of the textbook), at approximately what rate does the protein synthesis that assembles your hair strands deposit atoms in units of atoms per second? I need the second question to be rounded to 1 significant digit.
- I need help but I can’t put in scientific notation. Like 10^. ThanksA light-year (ly) is the distance light travels in one year (at speed of 2.998 ×× 108 m/sm/s ). An astronomical unit (AU) is the average distance from the Sun to Earth, 1.50 ×× 108 km. 1 year = 3.156 ×× 107 s. How many meters are there in 1.70 ly? Express your answer using three significant figures. Express in scientific notation! 1.70 ly = _________________m How many AU are there in 1.70 ly light-year? Express your answer using three significant figures. Express in scientific notation! 1.70 ly = _________________AUThere is one part to this question. I need to know the m/s. Thank you!
- Science fiction often uses nautical analogies to describe space travel. If the starship U.S.S. Enterprise is traveling at warp factor 1.71, what is its speed in knots and in miles per hour'? (Warp 1.71 = 5.00 times the speed of light; speed of light = 3.00 x 108 m/s; 1 knot = 2030 yd/h.)Usain Bolt from Jamaica holds the world record for the 100 meter race running it in 9.58 seconds. How fast is this in miles per hour? Assume that 100 is an exact number. 1 mile = 1.609 km.The answer is 30 but I don't know how it arrived at that answer! Please explain
