Determine el valor del desplazamiento para una persona que avanza hacia el norte 7 metros y después recorre 4 metros hacia el sur-este, formando un ángulo de 60° con la horizontal.

Two identical small charged spheres are a certain distance apart, and each one initially experiences an electrostatic force of magnitude f due to the other. with time, charge gradually leaks off of both spheres. when each of the spheres has lost half its initial charge, the magnitude of the electrostatic force will be

If the ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =

This is the substance(s) formed in a chemical reaction.
