QUESTION 1 (The Engineer, User information and Communication Systems) Engineers, scientists and technologists use information and communication technology in management decisions and when carrying out other activities such as research, design, development, production, maintenance and quality control. Choose any five engineering disciplines and indicate differences or similarities on how computers, networks and various types of software are applied by engineers in such disciplines. [10] QUESTION 2 (TVM and Project Selection) More and more people are experiencing the effects of global warming and climate change and fewer have doubts about it. A number of persons are expecting a transition to a low- carbon economy in the next number of years and decades where solar and wind farms and battery electric vehicles (BEVs) and fuel cell electric vehicles (FCEVs) are regarded as alternatives to fossil fuel based energy and transportation. Such infrastructure is, however, mineral and metal intensive and a number of minerals may be used to a larger extend than before. Lithium, cobalt, nickel and manganese are important for the manufacturing of batteries used in EVs. According to Seddon (2019) Argus expects the demand for lithium to increase 5,4-fold from 50000 tonnes in 2018 to 270000 tonnes by 2030 . This and predictions for nickel and cobalt are summarised in table 1 below. Table 1. Three important battery metals. Calculate the average annual compounded rate at which demand is expected to grow for each one of the three metals listed in table 1. In their Oil 2019 report the International Energy Agency forecasts that demand for oil will increase from 99,2 million barrels per day in 2018 to 106,4 million barrels per day by 2024 (Creamer, 2019). Calculate the average annual growth rate from this prediction and compare it with that of Li,Co and Ni
