Acharged particle is launched with a velocity of 5.2 × 10^4 m/s at an angle of 35° with respect to a 0.0045-t magnetic field. if the magnetic field exerts a force of 0.0026 n on the particle, determine the magnitude of the charge on the particle.

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.

Dshould be the right answer i think
