Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Currency Conversion
Currency conversion is the process of exchanging one currency for another, based on the current exchange rate. In this case, to find the price of gasoline in U.S. dollars, we need to convert euros to dollars using the given exchange rate of $1.15 per euro.

Conversion Factors
Volume Conversion
Volume conversion involves changing measurements from one unit to another, such as liters to gallons. Since the price of gasoline is given in euros per liter, we must convert liters to gallons to find the equivalent price in U.S. dollars, knowing that 1 gallon is approximately 3.785 liters.

Unit Price Calculation
Unit price calculation determines the cost per unit of a product, which in this case is gasoline. After converting the price from euros to dollars and the volume from liters to gallons, we can calculate the price per gallon in U.S. dollars, providing a clear understanding of the cost of gasoline in France.

Textbook Question
Force is defined as mass times acceleration. Starting with SI base units, derive a unit for force. Using SI prefixes, suggest a convenient unit for the force resulting from a collision with a 10-ton trailer truck moving at 55 mi per hour and for the force resulting from the collision of a molecule of mass around 10 - 20 kg moving almost at the speed of light (3×108 m/s) with the wall of its container. (Assume a 1-second deceleration time for both collisions.)

Textbook Question
A thief uses a can of sand to replace a solid gold cylinder that sits on a weight-sensitive, alarmed pedestal. The can of sand and the gold cylinder have exactly the same dimensions (length = 22 and radius = 3.8 cm). a. Calculate the mass of each cylinder (ignore the mass of the can itself). (density of gold = 19.3 g/cm3, density of sand = 3.00 g/cm3) b. Does the thief set off the alarm? Explain.
