The NS5 variety of these carry a magnetic charge, while the F-string variety carry an electric charge.
The pointlike type, in the presence of an external four-form field, puffs up into a fuzzy two-sphere, in an instance of the Myers effect exhibiting their dielectric properties with respect to Ramond-Ramond forms. The BFSS matrix theory is based on quantum mechanics of the type with zero spatial dimensions. The NS5 variety of these carry a magnetic charge, while the F-string variety carry an electric charge. The D(-1) variety are instantonic. In heterotic M-theory, one dimension is an interval with "end-of-the-world" ones at the boundaries. As one moves through spacetime, it sweeps out a worldvolume. The "0" type is pointlike while the "1" type is a string. For 10 points, identify these entities from string theory that occupy a certain number of dimensions, and whose "2" variety are usually just called membranes.

branes [Accept membranes before the final word. P-branes is acceptable at any time. D-branes or Dp-branes are acceptable answers until "NS5" is read.]
