¿Con que fuerza se atraen dos masas de 50kg y 700 kg que están separadas por una distancia de 5 cm?

 F = 9.338 10⁻⁴ N

Explanation:

For this exercise let's use the law of universal gravitation

          F =

let's reduce the magnitudes to the SI system

          r = 5 cm (1 m / 100cm) = 0.05 m

let's calculate

            F = 6.67 10⁻¹¹ 50 700 / 0.05²

            F = 9.338 10⁻⁴ N

the direction of the force is in the direction between the particles

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true
