Which method will correctly determine whether the forces on an object are balanced or unbalanced? add the forces in the horizontal direction to the forces in the vertical direction. add the forces in the horizontal and vertical directions separately. subtract the forces in the horizontal direction from the forces in the vertical direction. subtract the forces in the vertical direction from the forces in the horizontal direction.

Why do metals "give up" their valence electrons?

Robin is swinging back and forth from a trapeze. in which of the following situations is his kinetic energy being transformed into potential energy

One kind of e-book display consists of millions of very small spheres that float in a thin fluid layer between two conducting transparent plates. each sphere is black on one side and white on the other, and possesses an electric dipole moment directed from the white side to the black. when an electric field is applied between the plates, the spheres rotate so that their dipole moment lines up with the field. depending on the fields direction, either the black or the white sides of th espheres can be made visible.the dipole moment of the spheres can be modeled as two opposite charges of magnitude 3.5 x 10^-15 c, separated by a distancce of 100 micrometers (um). what is the maximum possible torque on a sphere if the electric field between the transparent plates is 4.0 x 10^5 n/c
