A teacher is introducing a lesson on force and motion and wants to encourage students to use process skills while discovering this information. What approach will ensure students are using process skills while working through the force and motion lesson?

Because the sun is the biggest and if the sun orbits the earth we will be dead probably

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

//(b) both involve the use of levers;

The answer is a your welcome
