An infinite line of charge with linear density λ1 = 7.4 μC/m is positioned along the axis of a thick insulating shell of inner radius a = 2.3 cm and outer radius b = 4.2 cm. The insulating shell is uniformly charged with a volume density of rho = -789 μC/m3.1) What is λ2, the linear charge density of the insulating shell?μC/m2) What is Ex(P), the value of the x-component of the electric field at point P, located a distance 8.7 cm along the y-axis from the line of charge?N/C3) What is Ey(P), the value of the y-component of the electric field at point P, located a distance 8.7 cm along the y-axis from the line of charge?N/C4) What is Ex(R), the value of the x-component of the electric field at point R, located a distance 1.15 cm along a line that makes an angle of 30o with the x-axis?N/C5) What is Ey(R), the value of the y-component of the electric field at point R, located a distance 1.15 cm along a line that makes an angle of 30o with the x-axis?N/C

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?
