La carga puntual q1 = -5.00 nC se encuentra en el origen y la carga puntual q2 = +3.00 nC está sobre el eje x en x = 3.00 cm. El punto P está sobre el eje y en y = 4.00 cm. A) Calcule los campos eléctricos E S 1 y E S 2 en el punto P debidos a las cargas q1 y q2. Exprese los resultados en términos de vectores unitarios (vea el ejemplo 21.6). B) Utilice los resultados del inciso a) para obtener el campo resultante en P, expresado con notación de vectores unitarios.

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!

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

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
