Willa, the cartoon witch, dusts her crystal ball with her silk scarf, causing it to become charged with 5.0 x 10^ -9 C. Willa then stares into the crystal ball and the wart on the end of her nose experiences an electric field strengths of 2200 N/C. How far is the trip of her nose from the center of the crystal ball?

Which of the following correctly describes what happens when an atomic bomb explodes? small pieces of fissionable material are joined and form a body with a mass greater than the critical mass, the relative number of neutrons escaping decreases, and a chain reaction and explosion result. large pieces of fissionable matter are brought together quickly and form a body with a mass smaller than the critical mass, the relative number of escaping neutrons increases, and a chain reaction and explosion result.
