PLEASE HEL Here is the question

5. How does the electric force (conceptually) change? (don't use K value)
5A. If one charge is doubled and the distance is tripled?
5B. If both charges are quadrupled and the distance is doubled?

5a?
5b?

Protons have a positive charge and, collectively, give an element its atomic number.

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.
