- 2.arrow_forwardWhat is the order of magnitude difference between something that works in nanoseconds and something that works in milliseconds?arrow_forwardA "bullet" train set a new world record for train speed at 552 kilometers per hour during a manned test run on the Test Line in April 1999. The Test Line is 42.8 kilometers long. How many minutes would a test run on the Test Line last at this record-setting speed?arrow_forward
- A common unit for speed used in sailing is the knot (nautical miles per hour). A nautical mile is about 1.15 regular miles. Calculate how much further (in feet) a boat moving at 22 knots will travel in 5 minutes compared to a car moving at 22 mph during the same time.arrow_forwardI am unsure if I should determine how many miles equal a kilometer or how many miles per hour equal kilometers per hour. A car travels with an average speed of 35 MPH. What is this speed in km/h?arrow_forwardThe population of India can be modeled by the function P(t) = 1462(1 +0.0177) where P(t) measures the population in millions andt represents the number of years since 2000. 1. Using this model, what was the population of India in 2009? 2. Predict the population of India in 2019. 3. If this growth rate continues, in what year will the population of India reach 2 billion people? Hint:arrow_forward
- Run up a flight of stairs as fast as you can, measure the time it takes and the height of one stair, and count the number of stairs. If you don't know your weight, measure that too. These measurements need not have three significant digits, but the calculated values do. Recall that 1 inch is about 2.54 centimeters, and 2.2 pounds is the weight of about 1 kg of mass.weight = 148.5 poundstime = 1.66 sheight of one stair = 18.5 cm, number of stairs = 12a. What is your power while running up stairs? Include units in your answer. b. The human body has an efficiency of about 28 percent. If you could maintain this stair-climbing pace around the clock, you could consume how many calories of food energy each day and not gain weight? (1 food calorie = 4186 joules)arrow_forwardA person's height is approximately 5 feet 2 inches. Express this height in the following terms. (a) meters m (b) centimeters cmarrow_forwardWe have a very large sheet of extremely thin paper. Assume that the paper is in fact only 0.1mm(0.0039inches)thick.Imagine that thispaper will be foldedin half repeatedly, 50 times.Guess how thick the paper will be at the end!Quick metric system converter: 10mm=1cm (about 0.39 inches)100cm=1meter ( about 3.3 feet)1000m=1kilometer (about 0.62miles)arrow_forward
- You are driving 52 mi/h and take your eyes off the road for "just a second" (exactly one second). What distance (in feet) do you travel in this time?arrow_forwardA car is traveling at a constant speed of 32.7km/h. It begins to accelerate at a rate of 6.2m/s2 for 9.2 seconds. How far (in meters) does it travel during this time? Do NOT include units in your answer. Round your answer to 2 decimal places. Do NOT change to scientific notation. Ignore significant figures.arrow_forwardA car travels with an average speed of 8.00 meter/second, What is the speed in km/s? What is this speed in mile/hour? Hint: 1km = 1000.0 meters, or 1 m = 0.00100 km; 1 mile = 1.60 km, or 1 km = 0.625 mile; 1hour = 3600.0 secondsarrow_forward
