ALWAYS use significant figure rules. Remember that these rules apply to all numbers that are measurements. In working on this problem, assume the value of "g" to be 9.8 m/s2 with two (2) significant digits unless otherwise stated.
Calculate the kinetic energy in joules of a 10 g bullet moving at 300 m/s.

J

A) 900
B) 450
C) 15
D) 45

Letter a, because when there are unlike charges they will always attract to each other.

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.
