19. Roller coaster engineer Ahmed's specialty is old-style wooden roller coaster, which have a considerable amount of friction. Because friction is an important factor in the roller coasters he designs and maintains, that friction must be taken into account. Which of the roller coaster designs shown would generate the largest amount of thermal energy as a roller coaster cart goes from the top of the hill to the bottom? a. Design X, which has the shortest track length. b. Design Y, which has a medium track length. c. Design Z, which has the longest track length. d. All three designs would result in the same amount of thermal energy by the time the cart reaches the bottom of the hill.

Power Transmission Elements

It is defined as the energy transfer from one location to another location. The energy will start moving from the energy generation source to the energy applied position to obtain the work output. From this method, a large amount of electric energy moves from the power station to various electrical substations.
