Asmall sphere with mass 5*10^-7 kg and charge is released from rest a distance of 0.500 m above a large horizontal insulating sheet of charge that has uniform surface charge density = 8*10^-12 c/m^2 .

using energy methods, calculate the speed of the sphere when it is 0.150 m above the sheet of charge?

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y < 4x − 8 y is greater than or equal to negative 5 over 2 times x plus 5 part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points) part b: is the point (5, −8) included in the solution area for the system? justify your answer mathematically. (4 points)
