The position of a particle as a function of time is given by x=(−5m/s)t+(3m/s2)t2. Find the average speed from t=0 to t=1s.
Express your answer using two significant figures.

Depending on how the continental plates move it can cause a continental scale shift.

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
