Besides air pollution, the student was concerns about water/ocean pollution. They heard many recent issues of too much plastic in the ocean and other pollutants in the water. The pie chart below provides data on the sources and amounts of different pollutants entering the oceans. first picture

The student read a news article that discussed the increase in amount of pollutants entering oceans and washing up on shores. The article included this image.

pick the answer

The greatest reduction in pollutants entering the ocean could be achieved if it were possible to reduce farm runoff/transportation/air pollutants/sewage/litter/ orindustry waste.

An charge with mass m and charge q is emitted from the origin, (x,y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
