Hullo! Physics student here! I'm struggling to figure out how to go about answering this question ): In one study of an adult bat, with a mass of 3.3 g and a wingspan of 111 mm, scientists found that this bat emitted a high-pitched sound that travelled 25.5 m in 78.7 ms.

- You place your ear onto a steel railroad track and hear the sound of a distant train through the rails Δt = 3.3 seconds faster than you do through the air. The speed of sound in steel is vs = 6100 m/s while in air the speed of sound is va = 343 m/s. Write an equation for the time it takes the sound to reach you through the air if the distance to the train is represented by D. Write an equation for the time it takes the sound to reach you through the steel if the distance to the train is represented by D. Use the difference in these two times to write an equation for the distance to the train. For the given information find the distance to the train in metersOn December 26, 2004, a great earthquake occurred off the coast of Sumatra and trig- gered immense waves (tsunami) that killed some 200, 000 people. Satellites observing these waves from space measured 800 km from one wave crest to the next and a period between waves of 1.0 hour. What was the speed of these waves in m/s and km/h? Does your answer help you understand why the waves caused such devastation?According to Timothy Treadwell in 2001 "Now, the bears I live with average, the males are on average twelve hundred pounds. They're the largest bears in the world and they've been clocked at 41 [mph] and they've run a hundred meter dash in 5.85 seconds which human on stimulants doesn't even approach. a. Compute the speed of a grizzly bear using Mr. Treadwell's hundred-meter statement. b. Compute the momentum of a grizzly bear using the speed you calculated in part a. and the average mass stated by Mr. Treadwell. c. How fast would a 250 lb man have to run to have the same momentum you calculated in part b? d. How fast would a 4000 lb car have to drive to have the same momentum you calculated in part b?

Here is a widely publicized, true story about how failing to convert units resulted in a huge loss. In 1998, the Mars Climate Orbiter probe crashed into the surface of Mars, instead of entering orbit. The resulting inquiry revealed that NASA navigators had been making minor course corrections in Sl units, whereas the software written by the probe's makers implicitly used British units. In the United States, most scientists use Sl units, whereas most engineers use the British, or Imperial, system of units. (Interestingly, British units are not used in Britain.) For these two groups to be able to communicate to one another, unit conversions are necessary. The unit of force in the SI system is the newton (N), which is defined in terms of basic Sl units as 1N=1 kg -m/s?. The unit of force in the British system is the pound (lb), which is defined in terms of the slug (British unit of mass), foot (ft), and second (s) as 1 lb = 1 slug · ft/s?.…During a thunder storm over the summer, you want to estimate the distance in kilometers (not miles!) of a flash of lightning: you count the number of seconds between seeing the flash and hearing thunder, and then you divide by 2. 3. 4. 5. none of the above
