I WILL REPORT YOU IF YOU DON'T ANSWER QUESTION OR IF YOU PUT A LINK You are asked to design an experiment that would wold allow you to measure the inertial mass of an unknown object. You decide to set up a modified Atwood experiment with a cart on a nearly frictionless track that is pulled by a mass hanging on a string that is draped across a pulley.
Which of the following includes the correct steps for a valid experiment needed to calculate the best value of the inertial mass for an unknown object?

Rain is pulled by gravity which is a non contact force

Good moring let me you on this question the answer the electric force  have a good day ; )

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
