systems. Actuaries analyze the financial costs or risks and uncertainty of the project.
Contractors oversee the project.
exhaust stroke correct answers In the exhaust stroke the piston comes up, pushing the burned
gases out of the cylinder. Together all four strokes (intake, compression, power and exhaust)
make two revolutions. While the engine is operating, the cycles repeat over and over again.
why involve students in their own evaluation correct answers Students can have an important

from a tungsten filament through a specimen and onto a screen; resolution is high enough to
view individual viral particles
Vidicons correct answers a small television camera tube in which the image is formed on a
transparent electrode coated with photoconductive material, the current from which varies as
