- Suppose velocity of an object is 5.7 miles per hour. When asking this as a question, say, what is velocity in m/s -- meaning meters/sec then we think dimensional analysis: 1 mile = 5280 ft, 1 ft = 12 in., 1 m = 39.37 in., 1 hour = 60 min, 1 min = 60 s In short ft to in to meters; also hours to min to seconds. -- dimensional analysis. However, in all this, do we think that avg velocity = change in distance/change in time. Please explain.arrow_forwardBe sure to answer all parts. Carry out the following conversions: (a) 1.25 light-years to miles (a light-year is an astronomical measure of the distance traveled by light in a year, or 365 days; the speed of light is 3.00 × 10° m/s) x 10 mi Enter your answer in scientific notation.

- Several hundred years in the future, humans discover an alien world named Noveria. On Noveria, time is measured in pjokas, which is equivalent to 5.93 seconds, There are 7 pjok in every pjokas (much like there are 60 seconds in a minute). If a Noverian alien watches 40 mok of cat videos, how many minutes is this?arrow_forwardA unit called the beard-second is the length the average beard grows in 1 second. A beard-second is defined as 10 nanometers (10 nm). The volume of the earth is approximately 259,875,159,532 cubic miles. What is this volume expressed in cubic beard-seconds? Some possibly useful conversions: 5280 feet = 1 mile, 1 quart = 0.946 liter, 2.54 cm = 1 inch, 1 week = 7 days, 12 inches = 1 foot. %3D The prefix nano means 10-9.arrow_forwardThere are 2600 miles between Boston and Los Angeles (in a straight line).
