b) The cylinder is made of a special alloy.
c) The cylinder is under pressure.
d) The cylinder has a specific weight tolerance.

Answer 1

The '+' symbol on a cylinder indicates that it is positively charged.

Step-by-step explanation:

The '+' symbol stamped on a cylinder indicates that the cylinder is positively charged. In physics, when two concentric conducting cylinders form a cylindrical capacitor, the charge on the outer surface of the inner cylinder is positive, which is represented by the '+' symbol. This means that there is an excess of positive charges on the cylinder's surface.
