Dos cargas q1 = -6,00 μC y q2 = +3,00 μC se encuentra localizadas en el vacío a una distancia de 4,00 m. Determine el trabajo realizado por el campo eléctrico para acercarlas hasta una distancia de 2,00 m. Exprese su resultado en J.

We found the centripetal acceleration of the earth as it revolves around the sun. compute the centripetal acceleration of a point on the surface of the earth at the equator caused by the rotation of the earth about its axis. (enter the magnitude. the radius of the earth is 6,371 km.)

Crowbar of 5 metre is used to lift an object of 800 metre if the effort arm is 200cm calculate the force applied

Wavelength,frequency,and energy are related.what happens to a wave as it’s wavelength gets shorter?
