Two resistors of 5.0 and 9.0 ohms are connected inparallel. a
4.0 ohm resistor is then connected in series withthe parallel
combination. a 6.0v battery is then connected tothe series-parallel
combination. what is the current throughthe 9.0 ohm resistor?

Aforce of 240.0 n causes an object to accelerate at 3.2 m/s2. what is the mass of the object?

Along the line connecting the two charges, at what distance from the charge q1 is the total electric field from the two charges zero? express your answer in terms of some or all of the variables s, q1, q2 and k =14ï€ïµ0. if your answer is difficult to enter, consider simplifying it, as it can be made relatively simple with some work.
