Aplane mirror and a concave mirror (f = 8.40cm) are facing each other and are separated by a distance of 22.0 cm. an object is placed between the mirrors and is 11.0 cm from each mirror. consider the light from the object that reflects first from the plane mirror and then from the concave mirror. what is the distance of the image (di) produced by the concave mirror?

If the force on an object is in the negative direction, the work it does on the object must be [2 points a) negative. b) positive c) the work could be either positive or negative, depending on the direction the object moves

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
