Warm air rising at the equator and cold air sinking at the poles is one reason for which type of movement of air?

Two thin 80.0- cm rods are oriented at right angles to each other. each rod has one end at the origin of the coordinates, and one of them extends along the x- axis while the other extends along the yaxis. the rod along the x- axis carries a charge of - 15.0 μ c distributed uniformly along its length, and the other rod carries 15.0 μ c uniformly over its length. find the magnitude and direction of the net electrical force that these two rods exert on an electron located at the point (40.0 cm, 40.0 cm). (e

The metric unit of electrical power is the watt volt ampere ohm

Will you chech and finish these for me, because i am stumped with them.
