171) A man of mass 60 kg, runs up the stairs of total height 5 meters in 4 seconds. How much power does the man exert? a. 750 W b. 250 W c. 1000 W d. 800 W weight = mass * gravity -> w=60*10 ... = 600N power = work/time -> p= (600*5)/4 = 750N 172) Which of these represents the correct order of some of the main energy changes that take place in a coal-fired power station? a. Kinetic, heat, electrical, chemical b. Chemical, heat, kinetic, electrical c. Chemical, electrical, heat, kinetic d. Heat, chemical, kinetic, electrical the chemical energy stored in coal is converted to the heat energy of water, which then converts to the kinetic energy of steam, which goes on to convert to electrical energy 173) A large amount of energy is produced in the center of the sun by which phenomenon? a.
