Consider a thin spherical shell of radius 15.0 cm with a total charge of +32.0 µC distributed uniformly on its surface.(Take radially outward as the positive direction.)(a) Find the electric field 10.0 cm from thecenter of the charge distribution. N/C(b) Find the electric field 25.0 cm fromthe center of the charge distribution. MN/C

For this car, predict the shape of a graph that shows distance (x) versus time (t). note that time is the independent variable and will be on the bottom axis. need asap

Light from two different sources are incident upon the same side of a polarizing filter. light from one source is polarized with total intensity ip, while light from the other source is unpolarized with total intensity iu. as you rotate the polarizing filter through 360 degrees, the intensity of the transmitted light on the other side varies by a factor of 9. what is the relative intensity of the initial polarized source to the unpolarized source, or ip/iu?
