A tourist purchases a car in England and ships it home to the United States. The car sticker advertised that the car's fuel consumption was at the rate of 40 miles per gallon on the open road. The tourist does not realize that the U.K. gallon differs from the U.S. gallon: 1 U.K. gallon = 4.545 963 1 liters1 U.S. gallon = 3.785 306 0 liters For a trip of 731 miles (in the United States), how many gallons of fuel does (a) the mistaken tourist believe she needs and (b) the car actually require?

Question list ✔ Question 6 ✔Question 7 Question 8 Question 9 Density of water = 1 lb₂ = 1 g/cm³ = 1000 kg/m³ = 62.4 lb/ft³ = 1.94 slug/ft³ Print Done K During processing, a polymer is pumped through the plant. The pump must produce enough power to move the material a height of 10 meters [m] at a volumetric flowrate of 0.2 cubic meters per second [m³/s]. Assume the specific gravity of the polymer is 0.6262. If the pump is 75% efficient, what is the power rating on the pump (input power) to supply the necessary potential energy in units of horsepower [hp]?

E1. Suppose that a pancake recipe designed to feed five people calls for 310 grams of flour. How many grams of flour would you use if you wanted to reduce the recipe to only feed two people? {A: E2. Suppose that a cupcake recipe designed to produce 16 cupcakes calls for 240 grams of flour. How many grams of flour would you use if you wanted to make 20 cupcakes? E3. It is estimated that eight medium pizzas are about right to serve a physics club meeting of 32 students. How many pizzas would be required if the group, due to a conflicting math club meeting, was only going to have 20 students in attendance? A: E4. A child uses her hand to measure the width of a tabletop. If her hand has a width of 8 cm at its widest point, and she finds the tabletop to be 16.5 hands wide, what is the width of the tabletop in cm? In meters? Ε11. Area is found by multiplying the length of a surface times the width. If a floor measures 5.28 m², how many square centimeters does this represent? How many square…

An object weighing 8 lbs hangs on the end of a spring, stretching the spring 3 inches. The object is in a medium that exerts a viscous resistance of 27 lbs when the object has a velocity of 6 ft/sec. Suppose the object is lifted an additional 8 inches and released. Find an equation for the object's displacement, u(t), in feet after t seconds. u(t) = Remember that, in imperial units, acceleration due to gravity is 32 ft/s? and that lbs are a measurement of force. Be sure to convert any measurements necessary so that the units match. Question Help: D Video D Post to forum - Submit Question
