In Geometry
intersection of the lines drawn perpendicular to each side of the triangle through its midpoint
Perpendicular lines passing through a point are at right angles to each other.
Yes, but only in principle. In practice, you won't live long enough. Putting it in more positive terms: No matter how many lines have already been drawn perpendicular to a given line [segment], there's always enough room for a lot more of them.
Any line that is not parallel to the given lines. The transversal that contains the shortest distance between the two parallel lines, is perpendicular to them.
In Geometry
Infinity
Lines are parallel if they are perpendicular to the same line. Since the lines m and l are parallel (given), and the line l is perpendicular to the line p (given), then the lines m and p are perpendicular (the conclusion).
They are perpendicular lines
One.
Infinite lines because a circle has infinite lines of symmetry.

Yes a virus can be attached through an email. The reason being by convention, electric field lines are drawn so that the elctric field vector E, is tangent to the lines at each point. Further, the numbe of lines per unit area through a surface perpendicular to the lines is proportional to the strength of the electic field in a given region.
