Which option identifies why Ethan's skills are valuable to his team in the following scenario? Ethan is a skilled engineer whose greatest strength is being able to take his team members' orthographic projections
and create isometric drawings from them.
There is no room for detail in an isometric drawing, so the detail is shown in the orthographic projection.
In an isometric drawing, multiple angles and axes can be shown in one sketch.
Only one sketch will be needed since all other previous designs will no longer be necessary.
Computer programs will not be necessary to create the exact dimensions of the design.

To save energy, the air supply to a 2000 ft office has been shut off overnight and the room temperature has dropped to 40°f. in the morning, the thermostat is reset to 70°f and warm air at 120 f begins to flov in at 200ft'/min. the air is well mixed within the room, and an equal mass flow of air at room temperature (changing with time) is withdrawn through a return duct. the air pressure is nearly 1 atm everywhere. ignoring heat transfer with the surroundings and kinetic and potential energy effects, estimate how long it takes for the room temperature to reach 70°f. plot the room temperature as a function of time.
