The strength of the gravitational force between two objects depends on two factors: mass and distance. Suppose that two objects attract each other with a gravitational force of 16 units. If the distance between the two objects is doubled, then what is the new force of attraction between the two objects? A) 4 units
B) 8 units
C)16 units
D)64 units

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

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
