A 32kg box is pulled at a constant speed along a horizontal surface by a rope with tension FT. The rope is inclined at an angle from the horizontal as shown. The block moves a distance 11m along the horizontal surface. What is the net work done by all the forces acting on the block? The acceleration of gravity is 9.8 m/s^2

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.
