Two points A and B are shown in the x-y plane with coordinates given in meters (m). A uniform electric field of magnitude V/m points in the +x direction. Given that the electric potential at point A is 100 V, determine the electric potential at point B (in volts). Note: The result may be positive or negative.

A small charged particle with mass × 10-6 kg is held at rest in a uniform electric field that points vertically upward and has magnitude 2 × 105 N/C. After being released, the particle accelerates with acceleration a = 2000 m/s2, as shown in the figure. Determine the charge on the particle (in nC).

For Dirofilaria immitis, the worm larva needs to develop and molt twice within the mosquito before it can be transmitted to a new dog host. In this new dog host, the adult worms mate and the females produce microfilariae that circulate in the blood. Also, please note that the mosquito is required for D. immitis to complete its life cycle.  What type of host and vector is the mosquito?
