Astudent wants to test if a bean plant will grow taller under green light than under sunlight. select from the drop-down menu the correct step of the scientific method that each statement describes.
two identical bean plants are grown next to each other. they receive the same amount of water and sunlight. one plant is covered with a green, light-filtering plastic cover, and the other with a clear plastic cover. measurements of the bean plants’ heights are recorded every day for two weeks.

An ideal otto cycle has a compression ratio of 8. at the beginning of the compression process, air is at 95 kpa and 27°c, and 750 kj/kg of heat is transferred to air during the constant-volume heat-addition process. assuming constant specific heats at room temperature, determine (a) the pressure and temperature at the end of the heat-addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. (4390 kpa, 1730 k; 423 kj/kg; 56.4%; 534 kpa)
