The charge of the first particle is -1.5 nC and the charge of the second particle is 2.5 nC. The particles are released are initially separated by 2.5 cm, having first particle released from rest position. The second particle is fixed at its location. What is the change in electrical potential energy when the first particle moved 1.0 cm?

My answer is opptionc, just check with anyone else

The answer is periosteum

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.

The answer is  the potential energy of the bob at position b is 1.47 joules.if the maximum height of the bob is 0.45 meters when it swings back,1.323   joules of energy was transformed to thermal energy.hope this
