2.- La masa de una esfera es de 4031.7 ± 0.2 g y su radio es de 5.00 ± 0.03 cm. Cual es el error relativo porcentual cometido en la medicion de su densidad ?

answer: good job it's all correct !

explanation:

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the components of a vector are the parts of the vectors that are to each other.
