Explain how the microstructure of 40% Sn - 60% Pb alloy forms as it is cooled from liquid state. Be sure to explain: different phases present, where the eutectic forms and when it forms.

grav forces affect all objects magnetic forces affect magnetic objects and electric currents

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
