Determine the potential energy and kinetic energy of a ball that has a potential energy of 10 Joules before it is dropped. The ball isn’t moving at the top position, is halfway down at the middle position, and is almost hitting the ground at the bottom position

Are there options for this?

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.
