What is the acceleration of a 1107 kg car as it comes to rest with a force of 2242 n in 6.9 seconds?

The answer is b.the gaseous state is electrically positive, while the plasma state is electrically negative. 

The objects are acted upon by only one force. gravity. mass times the acceleration of gravity (-9.81meters/second squared).

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.
