2. Suppose a car travels 108 km at a speed of 20.0 m/s, and uses
2.20 gallons of gasoline. Only 30% of the gasoline goes into useful
work by the force that keeps the car moving at constant speed
despite friction. (The energy content of gasoline is 1.3 ✕
108 J per gallon.)
(a) What is the force exerted to keep the car moving at constant
speed?
N
(b) If the required force is directly proportional to speed, how

1. Suppose that Adam's willingness To Pay (WTP) for a shirt of a particular brand is equal to 525. The market price of the brand is initially = $35 (thus, Adam's "consumer's surplus" SO, since he won't buy the shirt at that price). But then the brand becomes less popular (although Adam's WTP still equals 5 25; note that the Demand Curve will shift to the left when the brand becomes less popular). a.) Use a relevant graph to show...

In C++ Programming: Using a single for loop, output the even numbers between 2 and 1004 (inclusive) that iterates (loops) exactly 502 times. The outputted numbers be aligned in a table with 10 numbers per row. Each column in the table should be 5 characters wide. Do not nest a loop inside of another loop. Hint: First create and test the code that output the numbers all on one line (the command line will automatically wrap the output to new...
