Apoint charge of -6 mu or micro cc is located at x = 1 m, y = -2 m. a second point charge of 12 mu or micro cc is located at x = 1 m, y = 4 m.
(a) find the magnitude and direction of the electric field at x = -1 m, y = 0.
(b) calculate the magnitude and direction of the force on an electron at x = -1 m, y = 0.

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
