meter stick is pivoted at the 50 cm mark but does not balance because of nonuniformities
terial that cause it center of gravity to not be at the geometrical center. when weights of
nug and 200 g are placed at the 10 cm and 75 cm mark, respectively, balance is obtained. if the
weights are interchanged balance may again be obtained by shifting the pivot point to the 43 cm
mark. find the mass of the stick and the location of its center of gravity.

Ohm's law tells you that i = v/r where v is equivalent voltage and r is equivalent resistance of the circuit
since all circuits have the same voltage, your question is really asking which circuit has the lowest total resistance, since the lower the resistance, the higher the current
circuit a has a resistance of 5 ohms; circuit c is in series so has a resistance of 10 ohms; circuit b is in parallel and therefore has a resistance of 2.5 ohms (review your notes on adding resistances in parallel and series); therefore b has the highest current

I’m not sure about this question

Gotta have a picture ^^
