A student designed an experiment to test how changing the amount of voltage affects the current in a circuit. The student tested three series circuits. Each circuit contained three 5.0 Q resistors. The first circuit had a 1.5 V battery, the second circuit had a 3 V battery, and the third circuit had a 9 V battery. 5. What is the responding variable in this experiment? A. The amount of voltage B. The amount of resistance C. The type of circuit D. The amount of current

Much of the information taught in earth-space science would not be available if it weren’t for our remote sensing abilities. explain two ways our remote sensing strategies contribute to our knowledge of these topics.

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
