Re: Circuit Lab B/C

Next question: What is a relay and how does it work? A relay is an electrically controlled switch, kind of like a transistor. It can work in multiple ways, but one way (the most common way?) is for it to use an electromagnet. The electromagnet controls the switch by moving a conductor into position...

Re: 3.a.ii Device Walls

In rule 3.a.ii it says the "top and at least two vertical walls must be open or transparent for viewing all actions". I don't exactly understand what this means. Does this mean that any/all vertical walls have to be made out of a material like Plexiglas? What exactly does it mean by "...

Re: Botany B/C [TRIAL]

1) What 2 types of cells make up the xylem of a vascular plant? Are they dead or alive at maturity? 2) What are companion cells? 3) What is the Casparian strip and what is its purpose? If you don't realize from my questions, I really like plant anatomy. 1. Tracheids and Vessel Elements. Tracheids, ...

Re: Botany B/C [TRIAL]

Say we discover a planet that is completely covered with plant life (like, completely covered) that happens to exactly resemble plant life on Earth. Additionally, said planet also has life forms that can turn CO 2 into oxygen to keep the planet habitable for these plants. By taking measurements of ...

Does anyone know what +, !, and * mean in Boolean operations and logic gates?
! means not, * means and, and + means or. A+1 would mean that A is in an or gate with the other input being one, and A*0 would be A in an and gate with the other input as 0. I hope this answers your question.
