Gordon the night custodian dusts off a classroom globe with a feather duster, causing the globe to acquire a charge of -8.0 x 10°C. What is the magnitude and direction of the electric field at a
point 0.40 m from the center of the charged globe?

No because scientist are still changing there mines today so they are not correct to this day

An atom's smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to move. 

One answer could be erosion

How is it possible that phylogenies based on sequences from nuclear genomes and organellar genomes (i.e., chloroplasts and mitochondria) from the same group of species yield phylogenetic trees with different branching orders?   answer :   the genome of the endosymbiont is more closely related to members of the group in which it originally evolved, while the nuclear genome of the engulfing organism has its own evolutionary trajectory.
