Una carga de 0.80 nC se coloca en el centro de un cubo que mide 4.0 m a lo largo de cada borde. ¿Cuál es el flujo eléctrico a través de una cara del cubo?

Assume this car is driven off a cliff . how many arrows of force need to be drawn in the free body diagram? assume no air resistance -five -one -three -four

Aspring is used to stop a 50-kg package which is moving down a 20º incline. the spring has a constant k = 30 kn/m and is held by cables so that it is initially compressed 50 mm. knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest.

What quantity do units represent in value
