If the lens diameter is doubled, what happens to the resolvable angle of images produced at fixed wavelength? a. the angle decreases by a factor of two. b. the angle increases by a factor of four. c. the angle stays the same. d. the angle decreases by a factor of four. e. the angle increases by a factor of two.

Velocity is a description of both speed and direction, therefore it - a vector - a force arrow - the same as acceleration - a magnitude

What is the scientific definition of energy that relates to work

Calculate the ratio of h+ ions to oh– ions at a ph = 6. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1
