The hubble space telescope in orbit above the earth has a 2.4 m circular aperture. the telescope has equipment for detecting ultraviolet light. what is the minimum angular separation between two objects that the hubble space telescope can resolve in ultraviolet light of wavelength 95 nm?

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?
