Yes, but you will also need a pen or pencil. Also, if the line segment is very long (eg 5 metres) you may have difficulty in finding a compass that will do the trick!
No, it is not possible to construct a cube of twice teh volume of a given cube using only a straightedge and a compass.

Yes, it is possible to construct a perpendicular line that bisects a given line segment. To do this, you can use a compass and straightedge: first, draw arcs of equal radius from each endpoint of the segment to create two intersection points above and below the segment. Then, draw a line through these intersection points, which will be perpendicular to the original segment and will bisect it at its midpoint.
