Two spherical shells have a common center. A -1.7 10-6 C charge is spread uniformly over the inner shell, which has a radius of 0.050 m. A +5.2 10-6 C charge is spread uniformly over the outer shell, which has a radius of 0.15 m. Find the magnitude and direction of the electric field at the following distances (measured from the common center).(a) 0.20 m magnitudedirection(b) 0.10 m magnitudedirection(c) 0.025 m magnitudedirection

11. you want to calculate the displacement of an object thrown over a bridge. using -10 m/s2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?

Why do electron microscopes have higher resolving power than light microscopes?

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
