. Una esfera de aluminio se sumerge en agua. Si la densidad del aluminio es de 2.7 Kg/m³ y la del agua de 1000 kg/m³, ¿Qué porcentaje de la esfera se encuentra sumergida?

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.
