A point charge of +10 °C is at (+3 m, O m) on the x-axis and a point charge of +10 C is at (-3 m, O m).

1) Determine the work required to assemble this charge
distribution

2) Find the magnitude of the electric field at a point (0,+3
m) on the y-axis.

3) A charge q - +1°C is placed at a point (0, +3 m) on the y-axis.
Find the magnitude of the force on the 1C charge.

d. air pressure decreases as altitude increases.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods

conservation of mass

mass before something happens = mass afterwards

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
