Typically most fire marshal laws would require plenum cable.
Cat6 is the current standard for new installations of ethernet cable. Depending on the space and certain building codes you need to decide between Plenum (CMP) or Riser (CMR). The difference being Riser cable is more durable, but puts out toxic fumes when caught on fire, so it is not suitable for spaces with open air flow. Dropped ceilings are generally considered Plenum spaces so therefore require plenum cable.
You put time on the horizontal axis and distance on the vertical axis.
diaginald
yes because horizontal lines are across and vertical lines is up n down
Yes.
We start on the horizontal axis because of tradition. You would get the same results if you started on the vertical axis, as long as you continue to label the horizontal axis as the x-axis and the vertical axis as the y-axis.
Horizontal does not mean up or down. That would be vertical. Horizontal is left and right. Think of it like looking at the horizon.
On the horizontal axis you would probably plot the time. On the vertical axis you could plot displacement, velocity or acceleration.
A vertical line has an undefined slope. If a line is vertical, the horizontal coordinate, commonly known as the x coordinates, must all be the same. If not, the line would not be vertical.
(x, y)Open parenthesis, x coordinate [horizontal/latitude], comma, y coordinate [vertical/longitude], close parenthesis.For example, (2, 3) would be two spaces right and three spaces up from the origin. If you change the direction (again, from the origin), use negatives. (-2, -3) is two spaces left and three spaces down.
I assume you mean vertical, not verdical.The rectangle has 2 vertical lines, and 2 horizontal lines.
