1. (TCO A) The relationship between speed of innovation and product obsolescence is (Points : 5) direct (as innovation speed increases, products become obsolete more quickly). inverse (as innovation speed increases, products become obsolete more slowly). indirect (there is an effect, but it cannot be directly determined). nonexistent (there is no relationship at all).

Question 2.2. (TCO A) Which of the following products would be considered novel? (Points : 5) A detergent advertises that it can remove spots. A company announces it has produced a recreational hovercraft for sale in toy stores. A cell phone company announces that it now offers text messaging. A college

There are a variety of HEV types, and the degree to which they function as EVs varies as well. A hydrogen powered vehicle is also a kind of electric car. It runs on a motor powered by electricity. What makes it different from a battery-electric vehicle (or BEV) is where the electricity comes from. Instead of a battery, a hydrogen fuel cell car has, well, a hydrogen fuel cell. This is a device that takes hydrogen, the most abundant element in the universe, and generates electricity from it while the car is running. In effect, a hydrogen fuel cell is a kind of battery that makes electricity on the fly.
The great thing – and the green thing – about both electric cars and hydrogen fuel cell cars is that they don't produce any pollution at the tailpipe. Electric cars are easier to diffuse through the market as they are more advanced and are already in practical production. These are widely accepted across the globe. On the other hand, a hydrogen powered fuel cell will attract the following hardships:
1) Onboard Hydrogen Storage: FCVs are more efficient than conventional cars, and hydrogen contains three times more energy per weight than gasoline does. However, hydrogen gas contains only a third of the energy per volume gasoline does, making it difficult to store enough hydrogen to go as far as a gasoline vehicle on a full tank—at least within size, weight, and cost constraints.
2) Vehicle Cost: Fuel cell system costs have decreased significantly
